Augmented trabeculectomy with mitomycin C in primary congenital glaucoma

This study aimed to determine success of trabeculectomy augmented with mitomycin C (MMC) in children with primary congenital glaucoma (PCG) and document complications of this intervention. Over a two-year period, the authors treated 74 eyes of 42 children with PCG,...

Lacquer cracks

The purpose of this Japanese study was to analyse the morphologic features and natural progression patterns of lacquer cracks (LC). The presence of linear hyperfluorescence on the fundus fluorescein angiography (FFA) was used as the standard for diagnosing the presence...

Reduction of severe visual loss and complications following IAC for RB

This was a retrospective cohort study of patients with retinoblastoma (RB) who required intra-arterial chemotherapy (IAC) between 2013 and 2015, who had relapsed following systemic chemotherapy. A total of nine patients were included in the study and their ocular complications...

ABCA1 mediates lipid efflux in the retina

Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly population. There are two forms of AMD, dry and wet, the latter so named because of the presence of choroidal neovascularisation. Both forms lead to retinal pigment...

Nicotine accelerates diabetes induced retinal changes

This study investigated the influence of nicotine in an experimentally induced diabetic rat model. They used non-invasive high-resolution spectral domain optical coherence tomography (SD-OCT) imaging to provide quantitative information on the temporal alterations of retinal structures at the micrometer resolution...

Macular pigment in relatives of AMD patients

Blue light causes photo-oxidative retinal injury and macular pigment (MP), with lutein, zeaxanthin and mesozeaxanthin as the main components, as a filter that protects the macula from this damage. Previous studies indicated that low levels of macular pigment optical density...

A mouse model for uveal melanoma

Uveal melanoma (UM) is the most common malignant tumour arising within the eye and is a severe threat for both sight and life, due to a high risk of metastasis. There are no animal models of UM, but the Tg(Grm1)...

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)...

Risk factors and untreated POAG

The authors examined 50 untreated open angle glaucoma patients to determine if there was an association between the level of glaucomatous damage and documented risk factors. In this study the authors measured the extent of morphologic and functional glaucomatous damage...

Climatic droplet keratopathy

Climatic droplet keratopathy (CDK) is an acquired and potentially handicapping corneal degenerative disease that is highly prevalent in certain rural communities around the world. It predominantly affects males in their 40’s and is known by many other names such as...

Ranibizumab safety in pregnancy

Vascular endothelial growth factor (VEGF) plays a pivotal role during pregnancy, and systemic anti-VEGF administration during this period should thus be avoided. VEGF is expressed in multiple embryonic and foetal tissues during development, with the highest levels found in the...

Hot debates in medical retina and imaging: Perspectives from the Controversies in Ophthalmology 2020 virtual conference

Controversies in medical retina and imaging were debated during the Controversies in Ophthalmology 2020 virtual conference held during two mid-day scientific sessions on 27 and 28 March 2020. The author recounts key perspectives and presents viewpoint recommendations from the Vision...
