Sustained elevation of extracellular ATP in chronic glaucoma

Although adenosine 5′-triphosphate (ATP) release from retinal neurons and astrocytes has been demonstrated in short-term increases in intraocular pressure (IOP); such as in aqueous humor of humans with primary acute angle closure glaucoma, the response in chronic IOP elevation was...

A case series of acute visual loss following excessive alcohol and / or drug use

This study presents three cases of so called Saturday night retinopathy, an acute visual loss following intravenous drug abuse and stupor, leading to continuous pressure on the orbit while asleep. All three cases presented with acute vision loss and had...

Intraocular surgical training – is there any inter-procedural transfer of skills?

Cataract surgery is the most commonly performed surgery during ophthalmology training. This study aims to investigate how experience in simulated cataract surgery impacts and transfers to the learning curves for novices in vitreoretinal surgery. Twelve ophthalmology residents without previous experience...

Safety and outcome of microincision vitreous surgery in uveitis

This paper reports the outcomes of microincision vitreous surgery (MIVS) 23G/25G in uveitis of 103 patients (106 eyes) who underwent diagnostic MIVS over a period of four years at the Advanced Eye centre in Chandigarth India. The postoperative evaluation included...

Ranibizumab for the treatment of age-related macular degeneration

This multicentre randomised prospective open label study compared 0.5 versus 2mg of ranibizumab in patients with submacular retinal pigment epithelial (RPE) detachment due to age-related macular degeneration. Four treatment regimens were used for the two strengths either monthly for 12...

Ocular blood flow changes in Behcet disease

This study evaluates ocular blood flow changes in both ocular Behcets disease (BD) and non-ocular BD (with or without thrombotic disease) and compares these findings with a healthy control group. A total of 90 eyes with BD were evaluated with...

Early intraocular complications of aneurysmal subarachnoid haemorrhage

The aim of this study was to estimate the incidence of a whole spectrum of early intraocular complications in patients suffering from aneurysmal subarachnoid haemorrhage (SAH) and to identify factors that are potentially associated with these fundus findings. In total...

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...

Congenital aniridia clinical features

In this study the authors investigated the various ocular and systemic features associated with congenital aniridia in Indian eyes (262 eyes of 131 patients). The median age at time of first hospital visit was eight years (one day to 73...

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...

Effect of laser wavelength on delivering effective burns through opaque lens using pattern scan laser

Panretinal photocoagulation (PRP) has been used in the treatment of various retinal disorders for many decades. Conventional single-spot lasers take quite some time to do with significantly higher pain, anxiety and photophobia when compared to the pattern scan laser (PSL)....

An atypical presentation of Vogt-Koyanagi-Harada Disease

The authors present a single case of atypical presentation of Vogt-Koyanagi-Harada disease. A 42-year-old female presented with unilateral visual loss associated with systemic symptoms of fever and headache. Initial ophthalmic examination revealed a unilateral neuroretinitis, however, investigations for infectious and...
