Internal limiting membrane (ILM) peeling on blood flow in diabetic macula

This is a retrospective review of notes for diabetic patients with epiretinal membrane (ERM) who underwent surgery by the same surgeon. Nineteen had ERM peeling only, while the remaining 18 had both ERM and internal limiting membrane (ILM) peeling. The...

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...

Evaluation of keratometry with a novel colour LED corneal topographer

The Cassini topographer (i-Optics), which analyses corneal shape based on the reconstruction of specular reflections on 679 coloured LEDs, generates keratometry and is the new machine being compared in this study with other keratometry devices. The prospective comparative study included...

Relationship between nocturnal intraocular pressure elevation and diurnal intraocular pressure level in NTG patients

This group studies Korean normo-tension glaucoma (NTG) patients over a 24-hour period to assess if there was a relationship between nocturnal intraocular pressure (IOP) and diurnal IOP. They have previously suggested differences in diurnal IOP may have varying mechanisms of...

Glaucoma UK and The Royal College of Ophthalmologists announce research award 2024

Glaucoma UK and The Royal College of Ophthalmologists are collaborating to run this prestigious award which has previously funded a range of research topics from prospective stem cell treatments to the use of big data in patient risk stratification.

PRPF31-related retinitis pigmentosa and asymptomatic carriers

The authors present a study of 21 patients with variants in the PRPF31 gene classified as pathogenic or likely pathogenic. These variants are caused by autosomal dominant retinitis pigmentosa (RP-11). Between January 2020 and November 2021 patients underwent tests of...

Tear film thickness after treatment with artificial tears in patients with moderate dry eye disease

In recent years artificial tear drops addressing tear film osmolarity have come onto the market. Increased tear evaporation and reduced tear volume results in tear hyperosmolarity. This triggers an inflammatory process leading to apoptosis of goblet and epithelial cells. Trehalose,...

Effect of topical diclofenac on postoperative PRK pain: RCT

A major disadvantage of excimer laser photorefractive keratectomy (PRK) is pain and discomfort after the surgery, which is thought to be due to damage to corneal sensory nerve fibres or local release of inflammatory substances. Pain only resolves once corneal...

Visual recovery following Ex-Press vs. trab

The authors describe a prospective randomised study of 64 POAG subjects with controlled IOPs comparing visual acuity data in patients randomised to either Ex-Press model P50 or trabeculectomy. Visual acuities were recorded at baseline, day one, weeks one and two...

A case series of electroretinography findings in visual snow syndrome

The authors present a case series of individuals referred to an electroretinography (ERG) lab for assessment due to abnormal vision symptoms, over a two year period. Cases with visual snow syndrome (VSS) or isolated visual snow (VS) were included. All...

Intravitreal injection related endophthalmitis

This article reviews the incidence, clinical findings, risk factors, management and visual outcomes in intravitreal injection related endophthalmitis. Incidence of this complication is reported to be in the range of 0.038% to 0.065% (1 in 2000-3000 injections). Patients present typically...

Inhibiting high-risk corneal allografts

The cornea is an immune privileged site and as such corneal transplants are very successful. However, in situations where this privilege is lost the failure rises substantially. To combat rejection inhibition of the immune responses depends on steroids and other...
