Risk factors for consecutive XT

The authors report a retrospective study to investigate possible risk factors leading to consecutive exotropia development in patients who underwent two muscle strabismus surgery to achieve an initial alignment within 10PD. The exotropia group included 25 female and 22 males....

Strabismus and ocular motility, demystified

I am a former orthoptist, now trained in medicine and working as a foundation doctor. In my previous work, I was frequently approached by ophthalmology trainees eager for guidance with strabismus and ocular motility. Drawing on my clinical experience, I...

Supranuclear ocular motility disorders

Figure 1: Bilateral INO Introduction Complex ocular motility disorders are a diagnostic challenge. These patients come with very complex ocular motility presentations and require a careful and detailed assessment in order to find the correct diagnosis and arrange appropriate investigations....

Protecting retinal ganglion cells

Glaucoma is considered to be a heterogeneous group of conditions giving retinal ganglion cells (RGC) damage. Lowering intraocular pressure (IOP) reduces the risk of progressive RGC loss in glaucoma. Regeneration of the optic nerve has been shown to restore some...

Conservative management of concomitant strabismus

The aim of management for all patients with strabismus should centre around four goals: to prevent amblyopia, to alleviate symptoms, to restore binocular single vision (BSV) and to improve ocular alignment. The conservative management options available for strabismus include observation,...

Binocular single vision (BSV)

Introduction In this article I will try to summarise some of the definitions, tests and assessments performed in the strabismus clinic to assess patient binocular potential. This is a key feature of strabismus assessment, especially in adults, and it will...

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...

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...

Corneal neurotisation with an allograft

This is the first reported use of an acellular nerve allograft for corneal neurotisation. Seven patients received a 7cm long commercially prepared acellular nerve allograft. This was coapted to a functioning supratrochlear, supraorbital or infraorbital nerve and then tunnelled to...
