Ocular ischaemic syndrome in a rat model

Ocular Ischaemic syndrome is a devastating eye disease caused by severe carotid stenosis. This study’s purpose was to develop a reliable rat model for this syndrome by subjecting rats to common carotid artery occlusion and sham surgery. Rats were assigned...

Fluorescein angiography and OCT in myopic CNV

Fluorescein angiography (FA) and spectral-domain optical coherence tomography (OCT) are the most common examinations used in the management of anti-VEGF therapy in choroidal neovascularisation (CNV). In comparison to FA, OCT provides a noninvasive evaluation of the macula. Myopic CNV are...

Assessing the quality of scars from incisions made by a Colorado needle or a scalpel

Traditional teaching has held the best scars are achieved with cold steel although no previous study has formally investigated this hypothesis in oculoplastic surgery. This paper describes a non-randomised cross-sectional study comparing the scar quality achieved from cold steel with...

MicroRNA mediate retinoblastoma signal transduction

MicroRNAs (miR) are small non-coding single-stranded RNA molecules, normally 22 nucleotides long. There is a large family of miR that control protein expression by binding to mRNAs, leading to their degradation. One important role of miR is in tumours where...

MicroRNA inhibits corneal neovascularisation

MicroRNAs (miR) are small non-coding RNA that target mRNA for destruction. MiR target about 30% of the protein coding genes and fine tune their expression. MiR have been shown to be involved in several cellular processes including cell cycle, tissue...

PD-1 and PD-L1 in exenteration specimens

This is an immunohistochemical study looking at variation in the expression of the programmed death-1 receptor (PD-1) and the programmed cell death ligand-1 (PD-L1), comparing cutaneous malignancies which invaded the orbit with uncomplicated nodular basal cell carcinomas. The authors retrospectively...

Pterygium ocular surface temperature

This prospective study investigated the ocular surface temperature in patients with pterygia compared to those with dry and healthy eyes respectively. Previous studies have shown that patients with dry eyes show a significant decrease in ocular surface temperature on sustained...

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...

Complement factor B polymorphism and the phenotype of early age-related macular degeneration

The relationship between complement factor H (CFH) and age-related macular degeneration (AMD) is very well known, but other genetic polymorphisms relating to AMD are more poorly understood. This study was designed to investigate the relationship between complement factor B (CFB)...

Topical doxycycline for corneal neovascularisation

Six eyes with corneal vascularisation were treated with 1% topical doxycycline, four times a day for three weeks. The patients were reviewed at various intervals over a period of one year. The eyes selected had neovascularisation secondary to a variety...

Canaloplasty after failed trabeculectomy

The authors describe the technique of canaloplasty performed in five patients who had undergone previous trabeculectomy and under maximum tolerated medical therapy or insufficient intraocular pressure (IOP) control. Canaloplasty is described by the authors as “a nonperforating blebless technique derived...

A relationship between central serous retinopathy and obstructive sleep apnoea

This prospective study aimed to evaluate a relationship between central serous retinopathy (CSR) and obstructive sleep apnoea (OSA). Twenty-three subjects (six female and 17 male) were diagnosed with CSR and overnight polysonography was performed to record desaturation and apnoeic episodes....
