Reduction of mean acuity in INS with associated visual sensory defect is attributed to the underlying visual sensory defect and exceeds the acuity reduction of isolated INS.18 The rate of acuity development in children with albinism, aniridia, and mild to moderate bilateral optic nerve hypoplasia (BONH) parallels that of normal children. Zellweger is the most severe phenotype with severe hypotonia, neonatal seizures, neuronal migration defects, and hepatomegaly. Dacey DM, Liao HW, Peterson BB, et al. Gelbart SS, Hoyt CS. A complete blood cell count and femur radiography to evaluate bone density are recommended for infants with optic atrophy and congenital nystagmus for whom there is no obvious basis. Options include magnified visualization of the optic nerves with the direct ophthalmoscope or OCT, direct measurement of the optic nerve from fundus photographs obtained with the RETCAM or other instrument, or from magnetic resonance imaging (MRI) of the visual pathways. Atkinson and colleagues reported that only 5% of infants 6 to 9 months of age have more than 3 diopters of hyperopia and 0.5% more than 3 diopters of myopia.6 High hyperopia is most consistent with some forms of Leber congenital amaurosis (LCA) or early onset conerod dystrophy. Social and visual function in nystagmus. Nystagmus (ni-stag-muhs) is a condition in which your eyes make rapid, repetitive, uncontrolled movements such as up and down (vertical nystagmus), side to side (horizontal nystagmus) or in a circle (rotary nystagmus). Peroxisomal proteins are encoded by the nuclear genome, synthesized by free polyribosomes in the cytosol, and then bound to receptor molecules of peroxisomes, which internalize them. Involvement of PLEKHM1 in osteoclastic vesicular transport and osteopetrosis in incisors absent rats and humans. Annular deficiency of the central iris, along with corneal pannus, abnormalities of the iridocorneal angle, and propensity to develop glaucoma distinguish aniridia from other forms of macular hypoplasia. Their eyes move rapidly and uncontrollably in an up and down, side to side or circular motion. Of particular note, the presence of vertical or torsional nystagmus, strabismus, and abnormalities of eye movements may be the more sensitive indicator of increased intracranial pressure (ICP) than CT or MRI (personal observation). [38][39] Benefits of acupuncture for treatment of nystagmus include a reduction in frequency and decreased slow phase velocities, which led to an increase in foveation duration periods both during and after treatment. Nystagmus causes and risk factors include: Generally, nystagmus is diagnosed by an ophthalmologist. Infants with chiasmal gliomas come to medical attention with clinical features consistent with a diencephalic syndrome and nystagmus.49-52 The nystagmus is frequently monocular, small amplitude (<2deg), high frequency ( >5Hz), and either horizontally or vertically directed. Bilateral optic nerve hypoplasia (ONH) is the second most common cause of severe visual impairment with INS in children less than one year of age (retinopathy of prematurity is the first). There are a number of causes for 1967;2(1):4-10. Chair rotation testing involves sinusoidal rotation of the body with the head fixed around an earth-vertical axis at a peak velocity of 60 deg/s at frequencies ranging from .01 to 0.60 Hz. Congenital stationary night blindness (CSNB) includes a heterogeneous group of genetic disorders of the retina associated with reduced visual acuity ranging from 20/40 to 20/200, diminished vision in the dark, high incidence of nystagmus (50%) and normal fundi. WebPendular nystagmus can result from brain diseases such as multiple sclerosis, but can be a congenital problem as well. Clinical assessment begins with a careful review of the birth and developmental history. The primary physician to whom the family first presents is therefore faced with the daunting task of weeding through a broad spectrum of ophthalmological and systemic disorders. Pathological nystagmus is the result of damage to one or more components of the vestibular system, including the semicircular canals, otolith organs, and the vestibulocerebellum. Caloric testing entails irrigation of the external auditory canal with warm/cold air or water to elicit a conjugate eye movement. When acquired, it most often is caused by abnormalities of vestibular input. Cruz-Martin A, El-Danaf RN, Osakada F, et al. For example, CEP290 mutations have been documented in patients with LCA, Meckel Gruber, Senior Loken and Bardet Biedl syndromes. If you notice any changes in your vision or other related symptoms, call your healthcare provider right away. Colobomatous malformations of the optic nerve and/or macula are frequently associated with INS (see http://www.omim.org/or https://www.genetests.org). Brain tumor (rare cause of acquired nystagmus) All children and adults with new nystagmus should be WebThe cause of multidirectional and vertical nystagmus can be metabolic, toxic or structural so they can be seen with conditions as disparate as phenytoin intoxication, Wernicke's Table 1. Blindness from bad bones. Joubert syndrome (JS) is a genetic disorder in which INS (horizontal, pendular nystagmus) is frequently present. Head trauma. Pasadhika S, Fishman GA, Stone EM, et al. In medicine, the presence of nystagmus can be benign, or it can indicate an underlying visual or neurological problem. Nystagmus can be jerk (named for fast phase) or pendular, variable Electroretinograms (ERGs) are performed to quantify retinal function and to follow the progression of the disease and response to treatment. Nystagmus and related fixation instabilities following extraction of unilateral infantile cataract in the Infant Aphakia Treatment Study (IATS). Prevalence of vestibular and balance disorders in children. Causes of vestibular-related nystagmus. We do not endorse non-Cleveland Clinic products or services. Yamagata M, Sanes JR. Disorders of the vestibular end organ and the central vestibular pathways are underappreciated causes of nystagmus in childhood. Ophthalmoscopic examination may reveal an atrophic maculopathy, pigmentary abnormalities, or a normal-appearing fundus. The preponderance of crossed to uncrossed axons can also be demonstrated by showing asymmetric lateralization of pattern-onset visual evoked potentials (VEPs) under monocular viewing. Nystagmus is a condition of involuntary (or voluntary, in some cases)[1] eye movement, sometimes informally called "dancing eyes". WebThe most common central causes of dizziness and vertigo are cerebrovascular disorders related to the vertebrobasilar circulation, migraine, multiple sclerosis, tumors of the Retinal ganglion cell maps in the brain: implications for visual processing. Underdeveloped control over eye movements. These locations include the foramina of Monroe, the posterior 3rd ventricle, the aqueduct of Sylvius, the 4th ventricle, and the 4th ventricle foramina. The second one is nystagmus without another eye problem. Systemic symptoms and signs include progressive macrocephaly with bulging fontanelles, emesis, lethargy, seizures, focal neurological deficits, and failure to thrive. WebNystagmus, Multidirectional-Involuntary movements of the eye that are divided into two types, jerk and pendular. The test involves observation of the suspect's pupil as it follows a moving object, noting, The horizontal gaze nystagmus test has been highly criticized and major errors in the testing methodology and analysis found. Table 3 provides a list of the systemic diseases that are associated with conerod dystrophy. Although the detection of bilateral fundus colobomas can account for the nystagmus, absence of the semicircular canals and dysplasia of the vestibule may underlie a vestibular nystagmus. Infants with INS, reduced visual acuity, and normal fundi are likely to have LCA, cone dysfunction syndrome, or cone-rod dystrophy. In some cases, it may even limit the types of jobs and hobbies you can have. Of 1,196 patients whose abnormal electronystagmographic (ENG) traces were reviewed, 46 (3.8 per cent) showed DCPN. Gamlin PD, Zhang H, Clarke RJ. But it may be associated with serious health conditions, especially those affecting the brain, such as stroke, brain tumor, toxicity, head trauma and inflammatory diseases. Acquired nystagmus causes Acquired nystagmus describes symptoms that appear as early as six months of age, or any time after that. [3], In normal eyesight, while the head rotates about an axis, distant visual images are sustained by rotating eyes in the opposite direction of the respective axis. Additional considerations are Behr optic atrophy and OPA3.30Behr (1989) described a syndrome of heredo-familial optic atrophy beginning in early childhood that is associated with extrapyramidal tract signs, cerebellar ataxia, mental retardation, urinary incontinence, and pes cavus. Table 4. Many drugs/toxins cause nystagmus, particularly in overdose. A dedicated circuit links direction-selective retinal ganglion cells to the primary visual cortex. A survey conducted in Oxfordshire, United Kingdom found that by the age of two, one in every 670 children had manifested nystagmus. Aring E, Andersson S, Hrd AL, et al. Infants with obstructive hydrocephalus at the level of 3rd ventricle and aqueduct of Sylvius have highly characteristic oculomotor findings that reflect the response properties of the closely apposed oculomotor structures of the dorsal midbrain: paralysis of upgaze, light-near dissociation of the pupils, convergence-retraction nystagmus, eyelid retraction (Colliers sign), and conjugate downgaze (setting sun sign). Visual sensory disorders in congenital nystagmus. Physical or occupational therapy is also used to treat nystagmus. Srpskohrvatski / , Toxicity or intoxication, metabolic disorders and combination, Central nervous system (CNS) diseases and disorders, Note however that "dancing eyes" is also a common term for, Selective serotonin reuptake inhibitors (SSRIs), Infantile cerebellar retinal degeneration, Field sobriety testing Horizontal Gaze Nystagmus Test (HGN), "Incidence and characteristics of voluntary nystagmus", "Five novel mutations of the FRMD7 gene in Chinese families with X-linked infantile nystagmus", "A common NYX mutation in Flemish patients with X linked CSNB", "The number of procedures required to eliminate positioning nystagmus in benign paroxysmal positional vertigo", "Nutrition and Growth Guidelines | Domestic Guidelines - Immigrant and Refugee Health", "MRI magnetic field stimulates rotational sensors of the brain", "Diagnostic value of nystagmus: spontaneous and induced ocular oscillations", "Differences Between Physiologic and Pathologic Nystagmus", "Gaze-evoked and rebound nystagmus in a cerebellar syndrome", "Positional nystagmus and vertigo due to a solitary brachium conjunctivum plaque", "Vertical nystagmus: clinical facts and hypotheses", Muscular Dystrophy Association Press Release, "Many options to treat nystagmus, more in development", "The use of contact lenses to treat visually symptomatic congenital nystagmus", "Mini-telescopic eyeglasses suppress nystagmus", "Effects of acupuncture on foveation characteristics in congenital nystagmus", "Interventions for eye movement disorders due to acquired brain injury", "The prevalence of nystagmus: the Leicestershire nystagmus survey", Thygeson's superficial punctate keratopathy, Chronic progressive external ophthalmoplegia, Lesional demyelinations of the central nervous system, Experimental autoimmune encephalomyelitis, Leukoencephalopathy with vanishing white matter, Megalencephalic leukoencephalopathy with subcortical cysts, https://en.wikipedia.org/w/index.php?title=Nystagmus&oldid=1140339488, Wikipedia articles needing page number citations from August 2011, Short description is different from Wikidata, Self-contradictory articles from April 2014, Articles lacking reliable references from February 2021, Articles with unsourced statements from November 2015, Articles with unsourced statements from February 2018, Wikipedia articles needing clarification from January 2022, Creative Commons Attribution-ShareAlike License 3.0, Visual-motor syndrome of functional monophthalmus, Exposure to strong magnetic fields (as in MRI machines), Long-term exposure to low light conditions or darkness, called. Barricks ME, Flynn JT, Kushner BJ. Our providers specialize in head and neck surgery and oncology; facial plastic and reconstructive surgery; comprehensive otolaryngology; laryngology; otology, neurotology and lateral skull base disorders; pediatric otolaryngology; rhinology, sinus and skull base surgery; surgical sleep; dentistry and oral and maxillofacial surgery; and allied hearing, speech and balance services. Patients with gaze position differences often adopt a compensatory head turn to align the target at this eccentric gaze position where retinal slip is minimized and visual acuity is optimized. Acuity development in infantile nystagmus. Nystagmus is not to be confused with other superficially similar-appearing disorders of eye movements (saccadic oscillations) such as opsoclonus or ocular flutter that are composed purely of fast-phase (saccadic) eye movements, while nystagmus is characterized by the combination of a smooth pursuit, which usually acts to take the eye off the point of focus, interspersed with the saccadic movement that serves to bring the eye back on target. The cause is often unknown, or idiopathic, and thus referred to as idiopathic nystagmus. Many forms of acquired nystagmus may also be caused by disruptions of visual If you have nystagmus and are nearsighted, laser vision correction surgery such as LASIK may be beneficial. WebDirection-changing positional nystagmus (DCPN) is a nystagmus that changes its direction with different body and head positions. The pretectal syndrome in monkeys. Previously considered untreatable, in recent years several drugs have been identified for treatment of nystagmus. Farmer J, Hoyt CS. Infants with achiasma also come to medical attention because of seesaw nystagmus and reduced visual acuity. The main job for the clinician is to determine if the nystagmus is caused by peripheral vestibular disease or by involvement of the brainstem and cerebellar connections, said Steven L. Galetta, also at NYU Langone Medical Center. Your healthcare provider can help you find a treatment that works for you. The ipRGCs project to the pretectum (the midbrain region responsible for the PLR), the suprachiasmatic nucleus (SCN) (the area of the brain responsible for circadian rhythms), and the inter-geniculate leaflet. [36] Clinical trials of a surgery to treat nystagmus (known as tenotomy) concluded in 2001. Furthermore, the OCT may provide information about the underlying genotype and progression of disease. Types of early-onset nystagmus include the following, along with some of their causes: X-linked infantile nystagmus is associated with mutations of the gene FRMD7, which is located on the X chromosome. Affected males have decreased acuity, nystagmus, and myopia. WebDizziness is a general term for a sense of disequilibrium. Retina and Vitreous. Metabolic disorders are a rare but important cause of INS because of the presence of significant co-morbidities and treatment options. This is the American ICD-10-CM version of H55.0 - other international versions of ICD-10 H55.0 may differ. [35], Surgical treatment of congenital nystagmus is aimed at improving head posture, simulating artificial divergence, or weakening the horizontal recti muscles. Brain magnetic resonance imaging (MRI) reveals the characteristic molar tooth sign, which refers to the cerebral spinal fluid (CSF)-filled interpeduncular fossa, hypoplasia of the cerebellar vermis, and horizontally oriented and thickened superior cerebellar peduncles. Paradoxical pupillary responses in congenital stationary night blindness. Symptoms of nystagmus include: Uncontrolled eye movement. Of note, the oculomotor abnormalities often improve with increasing age. This improves focus and helps things look clearer when you cant hold a steady gaze. Visualization of the boundary between the hypoplastic optic nerve and the surrounding retina in the background of an eye in continuous motion is problematic. The predominant clinical findings are infantile nystagmus and cerebellar dysfunction (hypotonia and motor delays). Your brain controls your eye movement. If youve already been diagnosed with nystagmus, let your provider know if your symptoms worsen. High hyperopia is more prevalent in LCA. One is Oguchis disease, in which the fundus has a metallic sheen which diminishes after prolonged dark adaptation. Therefore, it is important to keep in mind that the nystagmus may be a manifestation of the underlying CNS or vestibular abnormality. The visual impairment is worse in the dark, but a subset can be light sensitive. The surgery aims to reduce the eye oscillations, which in turn tends to improve visual acuity.[37]. The skin pigmentation may be within the normal range but subnormal relative to that of other family members. For example, CRB1, important for establishment of epithelial polarity, co-localizes with the zonula adherens of the RPE, rod and cone photoreceptors, and Mller glial cells. The condition can be managed with glasses or contact lenses or rarely, surgery. Infants with suspected retinal disease need electroretinogram (ERG) testing but, owing to developmental immaturities of the ERG, testing is usually delayed until 6 months to one year of age. Table 3. [13][14] Rarely it may be due to a genetic condition that results in difficulties absorbing thiamine found in food. In albinism, the ratio of crossed to uncrossed axons is much higher, resulting in the loss of spatial overlap of corresponding nasal and temporal locations in the 2 eyes and the loss of binocular correspondence. Degeneration of the inner nuclear layer of the retina following lesions of the optic nerve. Normally, the ratio of crossed to uncrossed, retinofugal axons is 53:47 in the optic chiasm. Assessment of pupillary responses is a critical part of the clinical evaluation of the infant with INS. Behr C. Die komplizierte, hereditr-familire Optikusatrophie des Kindesalters: ein bisher nicht beschriebener Symptomkompleks. Children with congenital nystagmus usually have it in both eyes. Strabismus, binocular functions and ocular motility in children with hydrocephalus. In individuals with nystagmus, the areas of the brain that control eye movements dont work properly. Hydrocephalus is a common CNS abnormality with frequent onset prenatally or in infancy. Optic atrophy with paradoxical pupillary responses has been reported.59 Longitudinal evaluations disclose psychomotor regression, and brain MRI demonstrates absence or attenuation and progressive loss of CNS myelin. Brain MRI scans feature profound hypo-myelination, small and abnormal gyri, and neuronal heterotopia. Based on the pattern of isoelectric focusing of transferrin, patients are diagnosed with CDG-1 or CDG-2. Pupillary constriction to darkness. The direction of nystagmus is defined by the direction of its quick phase (e.g. Hypoxic ischemic injury can include damage of the brainstem, including selective damage of the vestibular nuclei.57Primary hydrocephalus or hydrocephalus secondary to intraventricular hemorrhage is frequently associated with vestibular nystagmus, owing to direct or remote pressure effects on vestibular pathways in the brainstem. Macular hypoplasia and INS are not unique to albinism but can appear in the context of aniridia and in bilateral congenital cataracts. Also, many blind people have nystagmus, which is one reason that some wear dark glasses. Tenotomy is now being performed regularly at numerous centres around the world. Policy. Localization of vestibular deficits is aided by the assessment of conjugate eye movements because they share neural structures that generate or calibrate slow and fast eye movements. It also may be induced temporarily by disorientation (such as on roller coaster rides or when a person has been spinning in circles) or by some drugs (alcohol, lidocaine, and other central nervous system depressants, inhalant drugs, stimulants, psychedelics, and dissociative drugs). Diseases of the central nervous system. distinct and sustained nystagmus at maximum deviation, and. The most common type is autosomal dominant optic atrophy, type 1 (OPA1). Half of the subjects failed to generate saccades or generated saccades that showed no consistent relationship with the direction, amplitude or timing of the stimulus. This constellation of oculomotor deficits is referred to as the dorsal midbrain or Parinaud syndrome. Nystagmus may be passed down from your parents, or it may be caused by another health issue. Type III 3-methylglutaconic aciduria (optic atrophy plus syndrome, or Costeff optic atrophy syndrome): identification of the OPA3 gene and its founder mutation in Iraqi Jews. Some patients can see clearly, while others may experience Nystagmus associated with some Congenital nystagmus. Good WV, Koch TS, Jan JE. Schulman JA, Shults WT, Jones JM Jr. Monocular vertical nystagmus as an initial sign of chiasmal glioma. [33] Several therapeutic approaches, such as contact lenses,[34] drugs, surgery, and low vision rehabilitation have also been proposed. Basic and Clinical Science Course, Section 12. Conerod dystrophy with onset in infancy is especially problematic because of the regional distribution of cone photoreceptors, phenotypical diversity, and association with a wide range of systemic diseases. CSNB with abnormal fundi include 2 distinctive entities. Bilateral cataracts are frequently associated with INS in developing countries, owing to late detection and delayed removal. Organizations: Patient organizations are available to help find a specialist, or advocacy and support for These disorders are characterized by early onset, mental retardation, minor facial dysmorphism, retinitis pigmentosa, sensorineural hearing deficit, hepatomegaly, osteoporosis, failure to thrive, and hypocholesterolemia with potential life expectancy to second or third decade. The cause of pathological nystagmus may be congenital, idiopathic, or secondary to a pre-existing neurological disorder. Weiss AH, Kelly JP. Congenital infections due to cytomegalovirus (CMV) are associated with hearing loss and vestibular nystagmus owing to viral-mediated damage of the hair cells within the cochlea and vestibular apparatus. Koeppen AH, Ronda NA, Greenfield EA, Hans MB. Acquired nystagmus can sometimes be corrected once the underlying condition is addressed. Therefore, the skin pigmentation of other family members should be assessed directly or from photographs. As the card is presented to the infant at a standardized distance, the examiner watches for a flick in fixation to the side of the grating through a small hole in the center of the card. A 29-year-old pregnant woman was admitted for hyperemesis gravidarum. Acquired nystagmus Gamlin PD, McDougal DH, Pokorny J, Smith VC, Yau KW, Dacey DM. This finding, referred to as saccadic initiation failure, reflects the underlying inability to either generate saccades or to generate accurate saccades in a timely manner. This finding should prompt neuroimaging to exclude JS and other forms of oculomotor apraxia. Nystagmus can be clinically investigated by using a number of non-invasive standard tests. Molecular testing reveals duplication or missense, insertional or deletional mutations of the PLP gene. Last reviewed by a Cleveland Clinic medical professional on 11/16/2021. Characteristics of the pupillary light reflex in the macaque monkey: metrics. A growing number of malformations of the brainstem and cerebellum associated with abnormalities in axonal routing and inter-neuronal connectivity can be associated with vestibular nystagmus as well as other gaze-holding instabilities (GHI).58. Midbrain eye signs in hydrocephalus. Owing to the wide variation in skin and hair pigmentation across racial and ethnic groups, the clinical diagnosis is most consistently confirmed on the basis of the ocular findings. Nystagmus can affect both children and adults. All conditions constituted by acute dizziness (with or without audiological symptoms), associated with nausea and/or vomiting, enduring a day or more, are included in the term acute vestibular syndrome [5,6].Potential causes range from benign to deadly, This type of surgery doesnt cure nystagmus, but it allows you to keep your head in a more comfortable position, thereby limiting eye movement. Relevant clinical features include history of similarly affected family members, meningitis, intracranial hemorrhage, trauma, or spina bifida. PMD gene encodes two proteins: proteolipid protein (PLP) and DM 20. The ocular fundi may be normal in appearance or there may be a bulls-eye or atrophic maculopathy, pigmented retinal stippling or optic nerve pallor. Functional abnormalities of this shared output likely account for the high prevalence of INS in patients with bilateral congenital corneal opacities, cataracts, macular hypoplasia (albinism and aniridia) and hypoplasia or malformations of the optic nerves. The observation of a PLR in the absence of rod and cone function,12 or following extinction of the illuminant, suggested there is an additional pupillary pathway. Birch EE, Stager DR. Pasik T, Pasik P, Bender MB. Two main types of nystagmus: pendular nystagmus (eyes move repetitively in a sinusoidal pattern) and jerk nystagmus (eyes move slowly in one direction and rapidly correct in the opposite direction). downbeat nystagmus, upbeat nystagmus, seesaw nystagmus, periodic alternating nystagmus. Reduced activity of the chloride channel is also critical to the transmembrane potential of the retinal pigment epithelium, leading to progressive chorioretinal degeneration. Acquired nystagmus in babies occurs at least several months after birth, with some cases occurring as early as 6 months old. A history of bacterial meningitis and/or exposure to systemic antibiotics, particularly aminoglycosides, in the perinatal period is potentially another risk factor for vestibular nystagmus. Disorders of cobalamins are rare, but mandatory newborn screening has led to increased and earlier detection. Anikster Y, Kleta R, Shaag A, Gahl WA, Elpeleg O. The direction of the slow phase component can be horizontal, torsional, or a combination of both directions when each of three canals is affected. The complete form of CSNB is associated with mutations of the genes GRM6 (metabotropic glutamate receptor 6), NYX (Nyctalopin) and TRPM1 (transient receptor potential cation channel). The infantile malignant form is due to a mutation in the human GL (grey-lethal) gene and failure to form osteoclasts resulting in early demise within 3-4 weeks of birth.33 Viable forms of osteopetrosis are characterized by increased bone density with narrowing of the internal lumen, resulting in compression of the optic and auditory nerves and pancytopenia. Likewise, inquiries concerning family members with neurologic, metabolic, or genetic disorders can suggest an underlying systemic disorder. Borderline ONH is associated with mild macular hypoplasia confirmed by OCT. Russell-Eggitt I, Harris CM, Kriss A. Huizing M, Dorward H, Ly L, et al. Pupillary area decreases with increasing irradiance over a 9 log unit range.9 The initial constriction of the pupil peaks at 200msec in response to the illuminant; however, the pupillary light response (PLR) persists for 30sec.10-11 The prolonged pupillary light response (PLR) is related to a unique sensitivity to short-wavelength blue light. A Behr-like syndrome designated OPA3 or Costeff syndrome was subsequently reported predominantly in females. The cause of multidirectional and vertical nystagmus can be metabolic, toxic or structural so they can be seen with conditions as disparate as phenytoin The remaining half generated targeted saccades that were either hypometric or hypermetric. Pong M, Fuchs AF. multiple sclerosis. Jerk nystagmus, the more common type, is characterized by eyes that drift slowly in one direction and then jerk back the other way. Treatment consists of learning strategies to compensate for the impaired system. Pelizaeus Merzbacher disease (PMD) is the most common form of hypomyelinating leukodystrophy (OMIM 312080) with X-linked inheritance. There are two types: congenital and acquired. Central nervous system disorders such as with a cerebellar problem, the nystagmus can be in any direction including horizontal. Some medications can reduce nystagmus symptoms in adults, such as gabapentin (antiseizure), baclofen (muscle relaxant) and onabotulinumtoxina (Botox).
