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...

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...

Surgical outcomes for constant and intermittent exotropia

This study evaluated the surgical results for constant and intermittent exotropia to investigate the factors that might influence the surgical results in a Scandinavian population. This was a retrospective study from 2011-2015 during which time 633 patients had strabismus surgery...

Early structural and functional retinal changes in intermittent exotropia

This study aimed to evaluate and compare spectral domain optical coherence tomography (SD OCT) and electrophysiological measures in patients with intermittent exotropia and healthy controls, to outline changes in retinal and optic nerve structure and function. This was a cross-sectional...

Correlations of fusional convergence with suppression depth in control of exotropia

This study was undertaken to investigate the differences in fusional convergence during refusion in patients with intermittent exotropia based on suppression depth and exotropia control. This was a cross-sectional study of 25 patients; 15 female and 10 male aged mean...

Autistic responses to plusoptix photoscreening

The authors sought to determine if the plusoptix would provide an accurate estimation of whether an autistic child had amblyopic risk factors. This retrospective study identified 48 children with autism. Undilated plusoptix was undertaken in 25 children aged less than...

BT for convergence spasm

The aim of this study was to analyse the response of a cohort of patients with convergence spasm to the injection of botulinum toxin (BT) in the medial rectus muscle. This was a retrospective study of six patients with a...

Residual esotropia surgery comparisons

The aim was to compare lateral rectus resection and plication methods in patients with residual esotropia for postoperative success rate, dose response, ipsilateral medial rectus limitations and reoperation. The study included 57 patients (31 female, 26 male) with 27 plication...

No risk of dry eye disease in concomitant strabismus cases

This preliminary assessment of the ocular surface of patients with concomitant strabismus before surgery was undertaken to determine if the presence of strabismus increases the risk of dry eye disease. This was a cross-sectional study of 204 patients with concomitant...

Functional outcomes after exotropia surgery

The authors used the Chinese version of the AS20 and A&SQ questionnaires to explore if successful postoperative alignment could significantly improve health related quality of life (HRQOL) in adults with childhood large angle exotropia. They further evaluated the relationship between...
