OBJECTIVE We wished to determine the effectiveness of horizontal rectus tenotomy in changing the nystagmus of patients with congenital nystagmus and, secondarily, how their visual function changed. DESIGN This was a prospective, noncomparative, interventional case series. PARTICIPANTS Ten adult patients with varied associated sensory defects and oculographic subtypes of congenital nystagmus...

Enlarged vestibular aqueduct (EVA) is one of the commonly identified congenital temporal bone abnormalities associated with sensorineural hearing loss. Hearing loss may be unilateral or bilateral, and typically presents at birth or in early childhood. Vestibular symptoms have been reported in up to 50% of affected individuals, and may be delayed in onset until adulthood. The details of nystagmu...

UNLABELLED Nystagmus tests to diagnose BPPV are still relevant in the clinical evaluation of BPPV. However, in everyday practice, there are cases of vertigo caused by head movements, which do not follow this sign in the Dix-Hallpike maneuver and the turn test. AIM To characterize BPPV without nystagmus and treatment for it. MATERIALS AND METHODS A non-systematic review of diagnosis and trea...

The authors assessed relationships between visual acuity and the amplitude, frequency, intensity, and duration of foveation periods in a retrospective study of 32 patients. Twenty-four patients had congenital idiopathic nystagmus, and eight patients had nystagmus and albinism. Visual acuity was determined for Landolt ring optotypes and, as the extrapolated high-frequency cutoff of the contrast ...

PURPOSE We wished to determine the effectiveness of horizontal rectus tenotomy in changing the nystagmus of children with infantile nystagmus syndrome. DESIGN This was a prospective, noncomparative, interventional case series in five children with varied sensory and oculographic subtypes of congenital nystagmus (including asymmetric (a)periodic alternating nystagmus) and no nystagmus treatmen...

background: it is mostly organic diseases that are considered when a neurological sign or symptom is present in the history of a patient; however, there may be psychiatric problems also present which could be missed. we report a case to discuss the possibility of the presence of an organic or psychiatric underlying disorder when facing neurological problems. case presentation: we report a case ...

OBJECTIVES To identify a congenital nystagmus locus on the X chromosome and to characterize the phenotype of a 4-generation family affected with congenital nystagmus and color deficiency. METHODS Sixty-five patients underwent an eye examination, including evaluation for the presence of nystagmus and color vision abnormalities. Affected patients and obligate carriers of the congenital nystagmu...

ALTHOUGH it has been recognized for a considerable time that operation on a strabismus co-existing with nystagmus may have a beneficial effect on the nystagmus, it does not appear to have been until 1953 that work was published relating to operation on cases of nystagmus with the direct intention of improving this condition. Then, from three different continents within a short time, separate re...

Electrophysiological measurement of the eye rotation axis using stimulation a single semicircular canal nerve showed that rotated around perpendicular to plane stimulated canal. Therefore, affected can be identified by analyzing in cases abnormal nystagmus. When main component nystagmus is horizontal, origin lateral torsional, anterior and/or posterior The excitatory quite same as inhibitory ny...
