Microtropia as an amblyopia indicator

This study was undertaken to determine if microtropia with identity (straight eye anisometropia) is a reliable indicator of amblyopia following optical correction. This was a retrospective review of 532 children aged four to five years. After two months of glasses...

VA and stereo changes with increasing Bangerter filters

This study investigated the effect of monocular blur induced by Bangerter filters (BF) on both monocular and binocular visual acuity (VA) and stereoacuity in normal visual systems. Subjects included 24 healthy student volunteers aged 20.33 ±1.79 years; 22 female. One...

Ophthalmic learning through the lens of cognitivism and constructivism

Learning in ophthalmology is multi-faceted, from understanding the fundamentals of eye anatomy and physiology to higher order skills such as performing cataract and vitreoretinal surgery. Having a strong foundation in the basics is a necessity for higher order knowledge synthesis,...

Sub-clinical detection methods in multiple sclerosis

Visually symptomatic multiple sclerosis (MS) provides only part of the required information to assist in understanding the disease. Recently, researchers have concentrated their efforts on diagnosing MS cases in the subclinical period. The aim of this paper was to assess...

Childhood glaucoma outcomes and prognosis

This study aimed to evaluate the relationship between clinical characteristics and visual acuity in childhood glaucoma. The study included 45 eyes of 31 patients; 33.3% with primary childhood glaucoma and 66.7% with secondary glaucoma; 53.4% of secondary cases had glaucoma...

End stage glaucoma management

A 48-year-old female has had multiple drug treatment for glaucoma and is still losing field of vision. How do you manage this over time? This patient is at high-risk for going blind and should be managed aggressively to protect remaining...

Translucent vs. lightproof occluders

This study investigates the change in visual acuity following occlusion in amblyopes and non-amblyopes using translucent versus lightproof occlusion of the dominant eye. Group 1 non-amblyopes consisted of 26 subjects: 16 visually normal and 10 strabismic or anisometropic subjects without...

GP contact lenses in nystagmus

The purpose of this study was to quantify and evaluate the effect of rigid gas permeable contact lenses (CLs) on visual acuity, contrast sensitivity and motor parameters of involuntary eye movements in hyperopic patients with infantile nystagmus syndrome (INS). This...

The clinical spectrum of albinism

The authors sought to examine clinical correlates that may be related to foveal development in albinism with an aim to qualitatively describe the phenotype spectrum of albinism. Binocular best corrected visual acuity ranged from 20/20 to 20/80. Best corrected visual...

Using bupivacaine to the medical rectus in addition to lateral rectus recession for convergence insufficiency type intermittent exotropia

This is a retrospective study of 60 paediatric optic pathway glioma (OPG) patients (NF1 or sporadic) presenting to Great Ormond Street between 2003-2017. Median follow-up was 82 months. Analysis was divided into best and worst eye vision representing level quality...

Comparison of vision screening programmes

The purpose was to examine the treatment that children underwent as a result of being identified with reduced vision at school screening. The level of improvement in vision was identified and the time taken to achieve maximum visual acuity. There...

Predicting ischemic lesion location using perimetry

The authors present a retrospective records review, using the search terms homonymous hemianopia, visual field loss and MRI. Only posterior circulation artery territory ischemic strokes were included. Demographics, stroke details and initial and follow-up with 24-2 SITA Standard perimetry results...
