Contrast sensitivity in myopic eyes
A classification system has been proposed for myopic maculopathy: grade 0 (no myopic retinal lesions), grade 1 (tessellated fundus), grade 2 (diffuse chorioretinal atrophy (CRA)), grade 3 (patchy CRA), and grade 4 (macular atrophy). Tessellated fundus is defined as the...
Age and prevalence of amblyopia in Ghana
The overall aim of this study was to determine the pattern and prevalence of amblyopia and assess the treatment options used in a rural hospital in Ghana.

Patients attending first referral hospitals in low- and middle-income countries (LMICs) receive surgical care that is just as safe and effective as that provided by higher level referral centres, a new study reveals. Researchers found no significant difference in 30-day...Ground-breaking achievements in blindness prevention
One small UK based charity is enabling pioneering research to prevent blindness in low and lower middle income countries. The British Council for Prevention of Blindness (BCPB), established in 1976, funds innovative research and training which seeds the development of...Myasthenia Gravis Masquerading as a Third Cranial Nerve Palsy

OCTA in geographic atrophy
In this article the authors aim to give an overview of the current literature concerning the application of OCT-A in geographic atrophy (GA). GA is a disease characterised by loss of outer retinal layers including photoreceptors, degeneration of the retinal...Acute retinal necrosis presumably caused by Epstein-Barr virus infection
Acute retinal necrosis (ARN) is an uncommon, but serious and potentially blinding condition. ARN is characterised by panuveitis, occlusive vasculopathy and progressive peripheral necrotising retinitis. The diagnosis is clinical but confirmation is sought via aqueous and vitreous sampling. Varicella zoster...Cortical blindness
Cortical blindness is a rare but recognised entity. Cerebrovascular accident is a well-known risk factor. We report a case of an 84-year-old lady with bilateral cortical blindness with multiple cardiovascular risk factors. Case report An 84-year-old lady was admitted under...On the wrong track
