In this paper, the authors present a case study of a patient whose nystagmus has a strong and exclusive male hereditary component. Genetic argumentation is presented in support of this conclusion. [ncbi.nlm.nih.gov]

It is present physiologically in everyone to a minor degree under certain conditions but it is often pathologic when exaggerated movements are present during normal visual activities. [disorders.eyes.arizona.edu]

The signs and symptoms of neurological disease are elusive by their very nature, presenting a confounding diagnostic challenge. [books.google.com]

Inheritance - congenital achromatopsia is transmitted in an autosomal-recessive trait Presentation - patients present in early childhood with nystagmus, abnormal visual behaviour or photophobia. Acuity is less than 20/200. [patient.info]

• Movement Disorder

  We work with people of all ages who have eye movement disorders. Our goal is to identify the cause of your eye movement disorder and help you receive the most effective treatment. [dukehealth.org]

  It is a type of bilateral involuntary eye movement disorder usually manifest as a slow movement in one direction and a rapid motion in the other direction. [disorders.eyes.arizona.edu]

  Each had variable clinical features, including segmental loss of pain and temperature sensation, muscle weakness and atrophy of the upper limbs and hands, nystagmus, urinary incontinence, and lower limb hyperreflexia and spasticity. [genome.jp]

  Progressive external ophthalmoplegia (PEO) is characterized by weakness of the eye muscles. [blueprintgenetics.com]

  You might have dizziness (vertigo), fatigue and muscle weakness during your episodes. In some cases, symptoms resolve in later life. Episodic ataxia doesn't shorten life span, and symptoms might respond to medication. [mayoclinic.org]

  An adduction weakness on conjugate movements and a jerk nystagmus of the abducting eye are the classic ocular motor signs (‘dissociated nystagmus’). [ncbi.nlm.nih.gov]

• Macula

  The macula has a high density of cones, ganglion cells, and pigment within bipolar and ganglion cells. The central 1.5 mm area of the macula is the fovea. [patient.info]

  Affected males have evidence of abnormal development of the central retina (macula) and the pigment of the retina appears irregular or 'mottled'. Females do not have this condition. General health is normal. [disorders.eyes.arizona.edu]

  Macular holes are thought to be caused by tractional forces associated with the vitreous gel separating from the retina in the macula and around the central macula called the fovea. [afb.org]

  Age-Related Macular Degeneration is the breaking down, or degeneration, of the macula area of the retina of the eye. Albinism the word “albinism” refers to a group of inherited conditions. [wnycvi.org]

  Fundus examination showed a radial pattern of hypopigmentation that spared the macula. There was foveal hypoplasia with some retinal vessels that crossed the macular area, confirmed by the absence of the normal afluorescence of the macula. [bmcgenet.biomedcentral.com]

• Torticollis

  Conversely, early developmental disturbances of vision often disrupt ocular motor control systems, giving rise to complex disorders such as nystagmus, strabismus, and torticollis. [books.google.com]

  Treatment: Treatment of amblyopia (visual impairment, which cannot be corrected with a correction lenses), balancing of the binocular vision and correction of torticollis (involuntary compensatory head position). [optometry-today.com]

  Onset prior to age 2 months, particularly in the setting of gaze-associated variable intensity and torticollis, strongly suggests idiopathic infantile nystagmus. [emedicine.medscape.com]

  If vertical torticollis is present, the vertical rectus muscles can also be recessed. Asymptomatic eye movements do not require treatment. [aao.org]

• Esotropia

  Esotropia The most common type of strabismus is esotropia, which occurs when either one or both eyes turn in toward the nose. Some children are born with this condition. More frequently, it starts at about age 2 1/2. [shileyeye.ucsd.edu]

  It is often seen in patients with congenital esotropia and following surgery for infantile esotropia, probably resulting from subnormal binocular interaction. [emedicine.medscape.com]

  An infant with a constant large-angle esotropia can be referred even earlier. [aafp.org]

  Epicanthus can obscure the inner canthus giving rise to the appearance of esotropia when none is present. [slideshare.net]

• Visual Acuity Decreased

  Effects on vision include decreased visual acuity, decreased central vision, decreased sensitivity in all visual fields, and nystagmus. OPTIC NERVE HYPOPLASIA (ONH) ONH is generally of unknown cause. [nfb.org]

  If the nystagmus is horizontal, the eye movement is usually "to-and-fro". [disorders.eyes.arizona.edu]

  Our present understanding of the genetics of hereditary nystagmus is somewhat limited. Few published medical sources have documented the existence of true cases of sex-linked hereditary nystagmus. [ncbi.nlm.nih.gov]

  Although the nystagmus frequency was also gaze-angle dependent, it was equal in both eyes. In the null region both nystagmus amplitude and frequency were minimal and equal for the two eyes. [journals.lww.com]

• Involuntary Movements

  It is a type of bilateral involuntary eye movement disorder usually manifest as a slow movement in one direction and a rapid motion in the other direction. [disorders.eyes.arizona.edu]

  Typical head tilt in a DSH female with Vestibular syndrome and secondary nystagmus Nystagmus is a neurological disease where there is an involuntary movement of one of both eyes. [vetbook.org]

  Nystagmus, a condition in which the eye has rhythmic and involuntary movement or oscillation, is often caused by an underlying neurological or ocular disorder. [livestrong.com]

  Nystagmus is a classified eye disease where the patient experiences an involuntary movement of the eyes in which they oscillate from side to side, up and down or even in a circular motion. [simmonsoptometrists.co.uk]

  Nystagmus acquired later in life may cause vertigo or dizziness like effects from the sensation of motion in the vision. Nystagmus may decrease when the eyes converge to read. [lowvision.org]

  You might have dizziness (vertigo), fatigue and muscle weakness during your episodes. In some cases, symptoms resolve in later life. Episodic ataxia doesn't shorten life span, and symptoms might respond to medication. [mayoclinic.org]

• Paresis

  Less common pontine lesions may have INO (1242,1361), and midbrain lesions may have vertical gaze paresis (1359). [neuroophthalmology.ca]

  In about 85% of the cases, the nystagmus is horizontal with the fast component directed towards the healthy hearing ear, suggesting a vestibular paresis on the side to which the slow phases are directed. [tchain.com]

  Other complaints such as convulsions, growth retardation, paralysis or paresis of the extremities, presence of convulsions, use of medication, history of surgery and other complaints are needed to be asked in detail. [omicsonline.org]

Treatment Treatment Options: Congenital nystagmus cannot be cured. However, several treatments may be beneficial. Glasses and contact lenses, and, occasionally, extraocular muscle surgery may be helpful. [disorders.eyes.arizona.edu]

What treatments are available for Nystagmus? Unfortunately, there are not many good treatments for nystagmus. For some specific types, medicines can help and surgery can be used to improve certain features, but for most, little treatment exists. [rnib.org.uk]

Current treatments, such as prism glasses, acupuncture, electronic nerve stimulation, contact lenses, various drug treatments, and others have had limited success. [clinicaltrials.gov]

At present, there is no treatment for this condition. [afb.org]

Prognosis - there is no progression. [patient.info]
