OCT in proliferative diabetic retinopathy

This report set out to describe the anatomical relationships between retinal neovascular complexes (NVC), the posterior vitreous, and the vitreoretinal interface in patients with proliferative diabetic retinopathy using spectral domain OCT. The following was recorded for each NVC 1) posterior...

Preoperative RPE alterations in macular holes

This retrospective interventional case series from Japan assessed whether preoperative alterations of the retinal pigment epithelial (RPE) in idiopathic macular holes correlated with postoperative functional and morphological changes in the macula. Fifty-nine eyes had preoperative Spectralis OCT using the ‘detailed’...

Retinoblastoma chemotherapeutic drugs and their toxic effects on RPE cells

There is reported clinical evidence of retinal pigment epithelium (RPE) alterations after intra-arterial (IAC) and intravitreal chemotherapy (IViC) of retinoblastoma. The purpose of this study was to investigate the cellular toxic effects of melphalan, topotecan and carboplatin on the RPE...

Long-term effect of gene therapy on Leber’s congenital amaurosis

After reporting the first successful gene therapy results for RPE65 deficiency in three patients in a brief report in 2008, the same team from London now report the results of 12 patients followed up for three years after transfection. As...

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...

Transfected RPE cells inhibit AMD in rats

Age-related macular degeneration (AMD) is a leading cause of blindness in the elderly. Wet AMD is characterised by choroidal neovascularisation, new vessels into the retina, leading to leakage and tissue damage. Many proangiogenic factors particularly vascular endothelial growth factor (VEGF)...

Are retinal vein occlusions seasonal? And if so why might that be?

Some studies have reported a strong seasonal pattern to central retinal vein occlusion (CRVO) occurrence with a peak in January, but other studies have failed to replicate this finding. The authors sought to determine data for Stockholm’s seasonal variation in...

Prognostic information for PRP-naive patients

The Diabetic Retinopathy Study group demonstrated that pan retinal laser photocoagulation (PRP) reduces severe vision loss by up to 50% in cases of proliferative diabetic retinopathy (PDR). The authors of this current study aimed to provide information for laser naive...

Ranibizumab versus laser in diabetic macular oedema (LUCIDATE study)

The aim of this study was to compare the functional and structural effects of Ranibizumab versus macular laser treatment in patients with diabetic macular oedema. It was a single centre, prospective, randomised, single masked clinical trial spanning a 48 week...

Macular thickness and visual fields

The authors describe a comparison of spectral domain OCT with Humphrey visual fields (HVF) mean deviation (MD) and pattern standard deviation (PSD), examining the retinal thickness of the macula and circumpapillary retinal nerve fibre layer (RNFL) defects. Seventy-three subjects who...

Association between serum triglycerides and pan retinal photocoagulation in type 1 diabetes

This retrospective cohort study aimed to examine whether dyslipidaemia is a risk factor for progressing to proliferative diabetic retinopathy (PDR) and consequently requiring pan retinal photocoagulation (PRP) treatment in type 1 diabetics. In previous studies including the ETDRS study an...

Case reports of ‘ictal lid saccades’ and ‘ictal blinks’

The authors present two cases of lid movements with discrete physiology and propose the terms ‘ictal lid saccades’ and ‘ictal blink’ to describe the movements seen. These two types of lid movement, blinks and saccades, have discrete kinematic properties and...
