Cancer associated retinopathy

Abdul Muhyemin Tarin reviews the presentation, pathophysiology and management of this paraneoplastic syndrome. Case presentation A 60-year-old hypermetropic female patient presented with several months’ history of painless blurred vision. Visual acuity (VA) was 6/24 and 6/9-1 in right and left...

IOP reduction and progression of high myopic glaucoma

This retrospective study of 131 eyes with high myopia (refraction >-6.0 dioptres or axial length >26mm), best corrected vision 20/40 or better, open angle and follow-up period of more than five years, were included from Korea. Based on the intraocular...

Oxymetazoline hydrochloride for improved symmetry in Graves’ disease

Oxymetazoline hydrochloride 0.1% ophthalmic solution has Food & Drug Administration (FDA) approval for use in involution ptosis. It is an alpha 1 agonist and partial alpha 2 agonist that stimulates Muller’s muscle to lift the lid. The authors of this...

Prediction errors of formulas in optical biometers

This study was conducted retrospectively in a private practice setting. Nine formulas were compared for prediction error (postoperative spherical equivalent (SE) minus, predicted SE calculated by each formula), using two optical biometers (Lenstar – optical low coherence reflectometry (OLCR) and...

Vitreous loss fire drills – ophthalmic simulation improves trainee surgical competence and confidence with posterior capsule rupture scenarios

Ophthalmic trainees have reported limited exposure and low confidence regarding the management of cataract complications such as posterior capsule rupture (PCR) / vitreous loss (VL). This report evaluates the impact of a simulation-based educational training event on these concerns. Introduction...

Bioengineered human tissue

This is a literature review of the current status of tissue engineering related to ocular and oculoplastic reconstructive surgery. The authors describe the process of bioengineering for tissue reconstruction. The aim is to reproduce functional tissue by the use of...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...

Myopia in Han Chinese

The authors present a case-control study of 361 patients with high myopia (mean spherical equivalent of -6.0DS or lower, and axial length greater than or equal to 26mm) and 749 healthy controls (mean spherical equivalent -1.0 to +1.0DS). They tested...

Predictors of IOP reduction after SLT

The aim of this study was to identify predictors of intraocular pressure reduction following selective laser trabeculoplasty (SLT) in patients with primary open-angle glaucoma, who are already taking maximally tolerated IOP-lowering medication and need further IOP reduction. In this prospective...

EDTA chelation for band keratopathy

The authors describe a retrospective analysis of 89 eyes from 72 patients who underwent ethlenediamine tetra-acetic acid (EDTA) chelation for band keratopathy. The ratio of R:L eye was 41:48. The mean age was 71 years (range 18-93 years). Thirty-two out...

Sex differences in the relationship between obesity and choroidal nevus in US adults

The National Health and Nutrition Examination Survey (NHANES); a population-based survey conducted annually in the US by the Centers for Disease Control and Prevention, was used to identify populations at higher risk for choroidal naevus. Over a period of four...

Proning and the pandemic - ocular complications seen in critical care

Priyanka Sanghi and her co-authors explore the ocular complications seen in critical care units throughout the country as we treat patients through this challenging time. The SARS-Cov-2 (COVID-19) pandemic has placed the NHS and critical care services under immense strain,...
