Incidence and risk factors of ocular hypertension following PPV and SOI

In this prospective, interventional study the authors evaluated the risk factors for elevated intraocular pressure (IOP) after pars plana vitrectomy (PPV) with silicone oil injection (SOI). This study included 254 eyes of 254 patients, with a mean age of 55.33...

Displacement of submacular haemorrhage – comparative study pneumatic displacement versus subretinal cocktail injection

The authors report a multicentre retrospective interventional case series study comparing the outcome of submacular haemorrhage (SMH) using pneumatic displacement with intravitreal expansile gas versus treatment with pars plana vitrectomy (PPV) versus subretinal injection of tissue plasminogen activator (tPA), anti-vascular...

Open globe trauma – visual outcomes after primary vitrectomy

This retrospective study aimed to evaluate the impact of early vitrectomy on visual outcomes in eyes with open globe ocular trauma. One hundred and eighty eyes from a cohort of 166 patients who underwent primary vitrectomy between 2017 and 2023...

Two cases of acute syphilitic posterior placoid chorioretinitis

Syphilis has re-emerged as a significant public health concern, with the World Health Organization (WHO) estimating that 8 million adults aged 15–49 acquired syphilis in 2022. Untreated syphilis can have severe consequences, including cardiovascular, neurological and ocular complications. Ocular manifestations...

Air tamponade in pars plana vitrectomy for primary rhegmatogenous retinal detachment repair

The authors report a study aimed to establish the use of air as a tamponade agent for primary rhegmatogenous retinal detachment (RRD) treatment, regardless of the position or the number of retinal breaks. Two hundred and thirty-six eyes of 230...

Submacular haemorrhage associated with nAMD: A meta-analysis and meta-regression on use of tPA and anti-VEGFs

The aim of this study was to evaluate the efficacy of a combination of tPA and anti-VEGF in the treatment of submacular haemorrhage (SMH) associated with neovascular age-related macular degeneration (nAMD). A systematic review meta-analysis following PRISMA guidelines, focusing on...

Update: Non-infectious retinal vasculitis

This review article summarises the update on non-infectious retinal vasculitis (RV). It is primarily classified based on the type of retinal vessels involved and further sub-classified as occlusive or nonocclusive. Clinically it can occur as an isolated ocular entity or...

VISION 2020 LINKS Programme and DR-NET World Sight Day Workshop

World Sight Day (WSD) was celebrated globally on 8 October 2020 [1]. From Australia and the Pacific to the Americas, via Asia, Africa and the Caribbean, awareness-raising and advocacy activities took place throughout the day, to focus attention on unnecessary...

Importing iron to the retina

In the retina, iron is particularly critical for the visual phototransduction cascade. In the retinal pigment epithelium (RPE), RPE65 activity leads to 11-cis-retinaldehyde, the photosensitive component of rhodopsin production and iron containing enzymes are necessary for disc replacement in photoreceptor...

Role of fundus autofluorescence patterns and baseline atrophy area on geographic atrophy progression

Central geographic atrophy (GA) is one of the morphological sub types of late-stage macular degeneration. The natural course of the disease is characterised by expanding areas of macular atrophy, which cause absolute scotoma. Fundus autofluorescence (FAF) is derived from lipofuscin...

Microperimetry of subretinal drusenoid deposits

Subretinal drusenoid deposits (SDD), originally termed ‘reticular pseudo-drusen’, have recently been identified by histology and optical coherence tomography (OCT) as aggregations located in the subretinal rather than the sub retinal pigment epithelium (RPE) space. These deposits affect the amount of...

Macular pigment and dark adaptation in older population with normal maculas

Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...
