Topical nonsteroidal ant-inflammatory drugs (NSAIDs) in patients undergoing cataract surgery

Inflammation is a major risk factor for the development of cystoid macular oedema (CMO) after cataract surgery, leading to breakdown of the blood-retina barrier. There is a correlation between severity of CMO and level of postoperative inflammation. Laser flare meter...

Brain abnormality as risk factor for consecutive exotropia

The authors evaluated and compared the cerebral MRI findings in operated infantile esotropia cases with and without consecutive exotropia. This was a retrospective study of 28 patients. Group 1 had 17 cases of consecutive exotropia with a mean follow-up of...

A robotic armrest for ophthalmic surgery

Robot-assisted ophthalmic surgery has been the focus of intense interest in recent years. In this study, the authors tested the potential utility of a robotic armrest in ophthalmic surgery. The iArmS device consists of a forearm rest attached to a...

Validity of coding in neuro-ophthalmology within large administrative datasets

A systematic review of validation studies of the International Classification of Disease (ICD) coding system, ICD-9 and ICD-10 is presented by the authors. Three searches were conducted based on three concepts, firstly health administration claims and ICD codes, secondly diagnostic...

The effect of caffeine on pupil size and accommodation

Twenty-two young and healthy participants were recruited in this study. The authors showed that pupil size increased as a result of caffeine consumption. A more stable (lower variability of accommodation) accommodative response (AR) was induced by caffeine intake, whereas the...

Characteristics of Charles Bonnet syndrome in patients with neovascular AMD

This retrospective cross-sectional study aimed to characterise various aspects of Charles Bonnet syndrome hallucinations among patients with neovascular age-related macular degeneration (AMD). Five hundred and ten consecutive patients were asked a screening question to determine if they had ever suffered...

Changes in drusen and retinal layer volumes prior to CNV development

This retrospective longitudinal study looked at patients with wet age-related macular degeneration (AMD) in one eye who subsequently developed wet AMD in the fellow eye. The aim was to discover whether drusen characteristics or volumes of retinal layers correlate with...

Restoration of colour perception in patients with retinitis pigmentosa

This is a case series testing the feasibility of using bioelectronic retinal prostheses to partially restore colour perception in seven patients with advanced retinitis pigmentosa. Bioelectronic retinal prostheses are able to bypass degenerated photoreceptors to directly stimulate the inner retinal...

Cataract extraction and microperimetry

In this study, the authors assessed retinal sensitivity before and after cataract extraction, in an effort to understand how lens opacities may affect microperimetry results in glaucoma and macular diseases. Thirty patients awaiting cataract extraction were examined and their lens...

Why is there subretinal fluid at the macula?

This is a review article looking at the differential diagnosis of subretinal fluid in the macula that could be diagnosed as central serous chorioretinopathy (CSCR). The authors have categorised them into 12 groups: neovascular diseases, vitelliform lesions, inflammatory diseases, ocular...

What is paracentral acute middle maculopathy?

This is a review article characterising a clinical entity called paracentral acute middle maculopathy (PAMM). The article highlights the fact that retinal capillary plexuses are organised predominantly into three trilaminar capillary layers occupying the area between the nerve fibre layer...

Visual retraining for homonymous hemianopia following stroke

This is a clinical trial evaluating the efficacy of motion discrimination training as a potential therapy for stroke-induced hemianopic visual field defects involving 48 patients. They were randomised into two arms, one intervention (deficit-field) and one control (sighted-field). Patients were...
