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...

Precision and accuracy of TearLab osmometer

Measuring tear osmolarity has been identified as a potential method for objectively diagnosing dry eye. TearLab osmolarity system is an in situ osmometer which may be a promising candidate for clinical use as it is portable and only requires a...

Meibomian gland dropout in patients with dry eyes

In this prospective study 264 patients with symptoms of dry eye were examined with a non-contact meibography system to assess the morphological changes in their meibomian glands. These patients were not previously diagnosed with meibomian gland dysfunction and patients with...

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...

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)...

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...

Detection of antiranibizumab antibodies in exudative AMD

In this study the authors aimed to detect immune response to ranibizumab treatment in wet age-related macular degeneration (AMD). An ELISA was employed to quantify the anti-ranibizumab titre which was compared against the control anti-abciximab titre. Titres of anti-ranibizumab antibodies...

RPE use similar pathway to regulatory T cells to inhibit immune response

Retinal pigment epithelial (RPE) cells form an important part of the blood-retinal barrier that protects the neuronal cells responsible for sight. RPE cells are involved in innate and adaptive immune responses via expression of surface molecules and release of cytokines....

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...

Intravitreal functional plasminogen in branch retinal vein occlusion

Branch retinal vein occlusion (BRVO) is the second most common vascular disorder of the eye. Intravitreal injections of anti-VEGF agents and corticosteroids have proven efficacy. Posterior vitreous cortex (PVC) adhesion has been shown to support the development of retinal vein...

Effect of voriconazole of vision of healthy volunteers

Voriconazole is a broad spectrum, triazole antifungal agent used for systemic fungal infections. It has a favourable safety profile and is available in both intravenous and oral forms. The commonest adverse drug reactions with voriconazole are changes in visual perception,...

Visual acuity after cataract surgery in AMD patients

The data from this study are obtained from the Age-Related Eye Disease Study (AREDS) 2 and analysed to evaluate if cataract surgery benefits patients with concurrent age-related macular degeneration (AMD). The AREDS 2 was a five year, prospective, multi-centre randomised...
