Can intravitreal anti-VEGF injections affect corneal nerves?

This was a retrospective case-control study looking at the effect of anti-VEGF injections on corneal nerves (CN). Fifty-seven patients with a history of at least three anti-VEGF injections in one or both eyes and available confocal microscopic imaging were included...

Air toxicity on retinal pigment epithelium

This study investigated the potential toxic effects of air on primary human retinal pigment epithelial (RPE) cells in vitro. Clinically during pars plana vitrectomy air is used as either a temporary tamponade during air-fluid exchange or mixed with gas to...

Clinical relevance of the anatomic classification of neovascular age-related macular degeneration

The author explains why an OCT-based classification of neovascular AMD is needed and how these neovascular subtypes may help to predict patients’ long-term visual outcome. Age-related macular degeneration (AMD) is a chronic and progressive neurodegenerative process involving the macula in...

Macula re-attachment following intravitreal ranibizumab in rhegmatogenous retinal detachment

Ranibizumab (Lucentis) is a vascular endothelial growth factor inhibitor (anti-VEGF) used for treatment of choroidal neovascular membrane [1]. We report a case where macula off inferior rhegmatogenous retinal detachment was misdiagnosed as wet age-related macular degeneration (AMD) and three intravitreal...

Environmental variations in endophthalmitis

In this retrospective cohort study, the authors looked at seasonal and environmental variations in 171 endophthalmitis cases out of 423,297 intravitreal injections. The incidence of this complication was not correlated to monthly snowfall, rainfall, or average temperature. There was no...

ANGPTL-4 inhibition reduces inflammation in diabetic retinopathy

Diabetic retinopathy (DR) is the most common cause of blindness in working-age humans, and numbers are rising due to increased cases of type 2 diabetes (T2D). T2D is associated with increased obesity and dyslipidaemia, which is a major risk factor...

Somatostatin protects retinal pericytes

Diabetic retinopathy (DR) is a complication of diabetes, caused by high blood sugar levels damaging the retinal microvasculature. Mechanisms, such as oxidative stress and deposition of advanced glycation end products, leads to glial cell activation and neuronal apoptosis. Pericytes, contractile...

Impact on the corneal and anterior chamber characteristics after femtosecond laser cataract surgery

Femtosecond laser cataract surgery (FLACS) is being increasingly used in the preparation for cataract surgery. Benefits of circular capsulorrhexis and reduced phacoemulsification energy have been shown in the literature. This study was designed to assess the anterior chamber characteristics and...

Refractive surgery for anisometropic amblyopia

The authors report the outcomes of refractive surgery with phakic intraocular lens (PIOL) implant for management of anisometropic amblyopia in children intolerant to conventional therapy. This was a retrospective study of 71 eyes of 71 patients of which 58 were...

Is an increased homocysteine level associated with greater risk of AMD?

Basic research studies have implicated homocysteine in causing vascular endothelial dysfunction and inflammation, and this has been borne out in large observational studies which suggested that elevated homocysteine is associated with increased risk of cardiovascular disease. In order to determine...

Clinical predictors of proliferative sickle cell retinopathy

Sickle Cell Disease (SCD) is an inherited disorder resulting in production of Haemoglobin S (HbS), which aggregates in conditions of hypoxia, acidosis or hyperosmolarity. This leads to vascular stasis, thrombosis and ischaemia. The authors present a cross-sectional study (45 consecutive...

Short-term effects of intravitreal bevacizumab on the cornea

Bevacizumab has been extensively used to treat macula oedema and neovascularisation of the retina and it has also been useful in the management of corneal neovascular diseases. This prospective study aimed to provide more information on the effect bevacizumab may...
