Diabetic polyneuropathy and risk of developing diabetic retinopathy

Diabetic polyneuropathy (DPN), diabetic retinopathy (DR) and diabetic nephropathy are widely classified as microvascular complications of diabetes. DPN, which may cause complete sensation loss, is another common complication of DM. The DPN-related diminished sensation presents a significant risk factor for...

Computerised visual acuity measurements in AMD

The aims of this study were to investigate whether half-letter width spacing in COMPlog algorithms had an adverse effect on agreement in patients with AMD with the ETDRS chart. Fifty adult participants with AMD took part with a median age...

Meibomian gland alteration in patients with primary chronic dacryocystitis: An in vivo confocal microscopy study

Chronic dacryocystitis affects tear film functionality and can predispose to ocular surface disease, however the specific effect of chronic dacryocystitis on meibomian gland function has not been studied. This group therefore performed in vivo confocal microscopy in 28 patients’ eyes...

The rarebit vision test for macular conditions

Rarebit testing is used to measure low degrees of neuro-visual damage and is available for free on the internet. It consists of a fixed bright light dot presented on a black background. During testing it is presented briefly at different...

Computerised tomography in ocular trauma patients

Ocular trauma can be common in military settings. This retrospective study looked into the relationship between the clinical effects of acute ocular and orbital blast trauma with the findings on computerised tomography (CT). This was a consecutive case series of...

Conjunctival melanoma involving the lacrimal drainage system

A total of 52 patients were diagnosed with conjunctival melanoma over a period of 17 years, 17 of whom required orbital exenteration. Five of these were found to have melanoma involving the lacrimal drainage apparatus (LDA). One was evident clinically...

Botulinum toxin after orbicularis myectomy

This is a retrospective review of 27 patients with benign essential blepharospasm who had become resistant to treatment with botulinum toxin and had therefore undergone orbicularis myectomy of the upper lids. The study compares the dose and frequency of botulinum...

Screening for ROP using wide-angle digital retinal photography by non-ophthalmologists

This is a systematic review article to evaluate the accuracy of digital retinal photography (DRP) performed by trained personnel (non-ophthalmologists) in diagnosing clinically significant retinopathy of prematurity (ROP). The authors used search engines including Medline, EMBASE, CINAHL and Cochrane databases....

Association between smoking and uveitis

This is a retrospective, population-based, case-control study from the general Kaiser Hawaii population. Over a two year period (1 January 2006 to 31 December 2007), there were 100 confirmed incident cases of uveitis. Two control groups were created, with 522...

Optic nerve head perfusion response to reduced blood pressure and increased intraocular pressure

The purpose of this prospective study was to test the hypothesis that blood flow autoregulation in the optic nerve head has less reserve to maintain normal blood flow where there is a blood pressure induced decrease in ocular perfusion pressure...
