Despite incessant to and fro motion of their eyes, persons with congenital nystagmus rarely report illusory motion of the visual world (oscillopsia). To determine whether insensitivity to retinal image motion prevents oscillopsia, thresholds for detecting horizontal and vertical oscillatory motion of a luminous dot target were measured in subjects with congenital idiopathic nystagmus and compar...

INTRODUCTION The aim of this study was to assess the effectiveness of displacement surgery in damping of ocular oscillation and management of compensatory head posture in patients of congenital nystagmus. METHODS This study was carried out in 2014. The participants were 50 patients with congenital nystagmus that dampens in a certain direction of gaze with or without abnormal head posture and ...

purpose: to present a case of spontaneous resolution of essential esotropia case report: a 22-month-old girl presented with eye deviation since the age of 4 month. in the first examination, visual acuity of both eyes was c+s+m+. the patient had 35 prism diopters of alternative esotropia in primary position and also bilateral inferior oblique overaction (iooa). there was no significant refractiv...

AIM To analyse nystagmus characteristics in patients with congenital stationary night blindness (CSNB) for differentiation from other forms of early childhood nystagmus. METHODS Horizontal and vertical eye movements of 10 patients (6-46 years, mean 17.1 years, median 12.5 years) with CSNB (eight with CSNB1, two with CSNB2) were recorded with the scleral magnetic search coil technique or by el...

Horizontal asymmetric nystagmus usually occurs in one of three situations: secondary to an intracranial lesion, with monocular visual loss, or as part of the triad that constitutes the diagnosis of spasmus nutans (asymmetric nystagmus, abnormal head posture, head shake). Clinical records of 277 children, presenting with congenital nystagmus over an 8-year period were reviewed. Nystagmus was asy...

The purpose of the current study was to identify novel mutations in the FRMD7 (FERM domain containing 7) gene and to characterize clinical features in Chinese patients with congenital motor nystagmus. For this purpose, 18 patients with congenital motor nystagmus were selected from the ocular genetic diseases bank of the Pediatric and Genetic Clinic of Zhongshan Ophthalmic Center (Guangdong, Chi...

Background: Pharmacological treatment has been successful in some forms of acquired neurological nystagmus. However, drugs are not known to be effective in idiopathic infantile nystagmus or nystagmus associated with ocular diseases. Methods: The authors retrospectively analysed Snellen visual acuity (VA), subjective visual function, and eye movement recordings of 23 patients with nystagmus (13 ...

Congenital nystagmus is a condition where the eyes of patients oscillate, mostly horizontally, with frequency between 2 and 10 Hz. Historically, believed to be caused by maladaptation oculomotor system thus considered disease brain stem. However, we have recently shown that congenital associated stationary night blindness synchronously oscillating retinal ganglion cells. In this perspective art...
