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...

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...

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...

The past and the future for paediatric ophthalmology

The past 25 years have seen remarkable advances in clinical eye care for children in the UK. This has led to both improved outcomes and better patient and family experiences. There have been substantial changes to patient pathways, major advances...

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...

Uncertainties and opportunities in ophthalmology training after the COVID-19 pandemic

Alexander Jones asks what impact the current pandemic will have on ophthalmology trainees. In my work as a Clinical Teaching Fellow, I have to admit that chaos is uncommon. Neither the anxious excitement of rushing to help an unwell patient...

AI-Based devices in national screening programmes: barriers and challenges

Diabetic retinopathy (DR) may have long-term complications and is recorded as a leading cause of blindness. National DR screening programmes have effectively reduced severe visual loss by timely detection and subsequent treatment of sight-threatening proliferative DR and diabetic macular oedema....

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...

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...

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...

Code-Free Deep Learning: a step into the future of ophthalmology

A new focus has arisen within the research domain of artificial intelligence (AI) in healthcare called code-free deep learning (CFDL), and recent research demonstrates that ophthalmology is becoming one of the leading specialties in this field. Artificial intelligence (AI) is...

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,...
