Amblyopia OCT results

The authors compared the macular and peripapillary retinal nerve fibre layer (RNFL) thicknesses of amblyopic and fellow eyes using Stratus optical coherence tomography (OCT) to reveal any differences. They sought to determine the anatomical differences between these subtypes of strabismic...

Stereo distance in XT

The test distance effect on stereoacuity was explored in a population with intermittent exotropia along with use of two types of stereograms with crossed and uncrossed disparity. At near and distance distances, the median for both disparities was 60”; 79%...

Risk factor for surgical failure in consecutive XT

This study was designed to determine the success rate among patients with consecutive exotropia after choosing an appropriate surgical method based on medial rectus function and level of exo deviation. The authors conducted an interventional case series study of 40...

A case series of acquired esotropia in cerebellar disease

Acquired esotropia in cerebellar disease is well described but under-recognised. The pathogenesis of cerebellar esotropia is controversial. It is suggested it may be a result of disruption to central vestibular pathways. This article reports a case series of seven adults...

Surgical results in spinocerebellar ataxia (SCA)

Patients with SCA frequently develop ocular motility abnormalities including nystagmus, abnormal smooth pursuits, dysmetric saccades, divergence paresis and ophthalmoplegia. Incidence of diplopia is higher in SCA type 3. The purpose of this study was to evaluate surgical responses and outcomes...
