OCT in peripheral corneal thinning
This small retrospective study used high resolution optical coherence tomography (OCT) Heidelberg Spectralis to identify features which could determine the underlying aetiology of peripheral corneal thinning. Ten patients were included; five with diagnoses of degenerative peripheral thinning; Terrien’s marginal degeneration...In conversation with Dr Monicah Bitok, Global Inclusive Eye Health Advisor (CBM)
Eye News spoke to Dr Monicah Bitok, Global Inclusive Eye Health Advisor with the Christian Blind Mission (CBM), about the rise in diabetes-related preventable blindness, systemic ophthalmic changes in low- and middle-income countries, and the impacts of a COVID-19-induced backlog...
A comparison of colour vision tests in the presence of contrast sensitivity loss
This study analyses the effect of contrast sensitivity (CS) loss on colour vision (CV) testing, using a variety of colour vision tests. The authors used a computer model for CS loss to determine its effect on CV testing scores for...
High myopia macular thickness
The purpose of this study was to compare macular thickness and volume in 15 highly myopic (>-6D) young children with 11 age-matched controls (-2 to +4D refractive errors) using Stratus third generation OCT. Mean spherical equivalent was -9.42 ±2.81D for...The management of watery eye in an infant with facial dysmorphism
A six-month-old child with facial dysmorphism is brought to the eye clinic with history of watery right eye since birth. How will you manage this child? Causes for watery eye in an infant 1. Overproduction of tears a. Infections b....
Reduced blood flow and age-related macular degeneration
This was a prospective cross-sectional study assessing changes in blood flow velocity in patients with age-related macular degeneration (AMD) using a retinal function imager. Sixty eyes with wet AMD were compared to 53 control eyes and the average blood flow...
Delayed improvement in Muller’s muscle ptosis surgery
This is a retrospective review of patients undergoing ptosis surgery. The authors had noticed anecdotally that although a posterior approach Muller’s muscle and conjunctival resection (MMCR) appeared to achieve similar results to an anterior approach levator resection (ALR) in the...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...REPORT: American-European Congress of Ophthalmic Surgery (AECOS) European Symposium
David Shahnazaryan, Consultant Ophthalmologist, London, UK and Radhika Rampat, Consultant Ophthalmologist, London, UK, report from the AECOS Symposium in Antwerp, Belgium (June 10-12).Portable corneal topography – exploration of a prototype
Ophthalmic imaging devices, such as corneal topographers, are not widespread in the developing world. A small device that connects to a smartphone might be a solution to improve developing nation access to corneal imaging. I recently had the opportunity to...
DMEK versus DSAEK
This systematic review and meta-analysis reviewed published evidence comparing two endothelial corneal transplants techniques; Descemet membrane endothelial keratoplasty (DMEK) and Descemet stripping automated endothelial keratoplasty (DSEAK). DMEK involves transplanting Descemet membrane with endothelial cells without any overlying stroma. In DSAEK...
