Comparison of bilateral lateral and unilateral recession resection for IXT

This is a retrospective review study of patients between the ages of three and 15 years old with the basic type of intermittent exotropia (IXT) who had strabismus surgery between January 2003 to September 2009. There were 85 patients included...

Association of asthenopia and heterophoria

Heterophoria varies over time and asthenopic symptoms may be greater when the heterophoria is larger. Thus a close intra-individual correlation may exist between heterophoria and discomfort during reading. The authors investigated the variability of both parameters in 20 individuals who...

Association between colour vision impairment and amyotrophic lateral sclerosis (ALS)

The purpose of this study is to test the hypothesis that colour vision impairment is associated with amyotrophic lateral sclerosis (ALS). Abnormalities of the inner and intermediate retinal structures in patients with ALS have been described using optical coherence tomography...

AC/A correlates

Three groups of subjects were included in this study. Group 1 had typically developing children from five to nine years with heterophoria less than 6PD. Group 2 had 19 children aged five to nine years with intermittent distance exotropia. Group...

An interesting presentation of ruptured anterior communicating artery aneurysm with acute monocular vision loss

The authors report an interesting case of a 60-year-old man presenting with acute monocular vision loss accompanied by periorbital pain as an unusual presentation of subarachnoid haemorrhage (SAH) from ruptured anterior communicating artery aneurysm. The patient did not present with...

Can the angle of origin of the ophthalmic artery predict embolic trajectory?

A retrospective, comparative case-control study was used to test the hypothesis that a risk factor for retinal versus cerebral infarct is the angular origin of the ophthalmic artery from the internal carotid artery. The study compared one group (n=28) who...

Augmented surgery with BTA for large angle strabismus correction

This retrospective study reports the results of botulinum toxin A (BTA) augmented bilateral recession or monocular recession / resection (RR) for patients with large angle strabismus. Twenty-four patients were recruited: 10 female, mean age 9.2 ±13.6 years, 20 esotropia and...

What plane should be used for ultrasound measurement of the optic nerve sheath diameter?

This prospective observational study aimed to evaluate the differences between optic nerve sheath diameter (ONSD) between the patients’ two eyes and different ultrasound planes (transverse and sagittal). Participants were recruited over a two-year period from a single neurosurgical department. To...

Comparison of thrombolysis and conservative management in acute retinal ischaemia

The authors present a retrospective cohort study of individuals presenting with acute, painless, monocular vision loss and diagnosed with acute retinal ischaemia. Reasons for exclusion were iatrogenic aetiology, transient vision loss, missing initial visual acuity data, more than 16 hours...

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...

Sixth nerve palsy versus decompensating distance esophoria

Orthoptists see a wide range of conditions that can range from reduced binocular single vision (BSV) that may be solved with exercises, to more extreme neurogenic cases requiring further intervention. Because of this variety, it is important to be able...

Which factors predispose to pingecula development in a rural Chinese population?

The authors report a cross-sectional study which aimed to determine the prevalence and risk factors for developing pingecula in a rural Chinese population near Shanghai. Nine hundred and fifty-nine persons were recruited from a single village and asked to complete...
