WATCH EPISODE 9: Beyond 2020 with the Andean Medical Mission

Welcome to the 9th episode of Beyond 2020, the series that looks at strategies to eliminate avoidable blindness in countries with developing eyecare services and shares ideas and solutions to common difficulties in working abroad.

Multimodal Retinal Imaging

Understanding of rapidly advancing retinal imaging techniques is important as they have changed the management of retinal conditions considerably. Interpretation of these tests is a vital skill in the armamentarium of every practising ophthalmologist. The book is directed at general...

The Surgeon

The Surgeon is a short, fictional story based in the (very) near future, 2030. It covers the investigation of a politician who died during routine heart surgery carried out by a prominent cardiothoracic surgeon using a robotic system/AI (called A.I.R)....

A comparison of colour vision tests in the presence of contrast sensitivity loss

This study analyses the effect of contrast sensitivity (CS) loss on colour vision (CV) testing, using a variety of colour vision tests. The authors used a computer model for CS loss to determine its effect on CV testing scores for...

Dilate or not in subconjunctival haemorrhage?

There is often surprisingly little evidence in common clinical conditions. Spontaneous non-traumatic subconjunctival haemorrhage (SCH) is frequently encountered in emergency and walk-in clinic visits. In some centres, a dilated fundus exam is performed to exclude retinal pathology. This retrospective study...

Pseudotumor cerebri (PCT) is a disorder causing increased intracranial pressure without a mass lesion, usually seen in obese women of childbearing age. Idiopathic intracranial hypertension is an idiopathic form of the disorder, but several medications have been associated with the...

Biomechanical stabilisation of ocular measurements post cataract surgery

This prospective study looks into the time duration of biomechanical stabilisation post uneventful cataract surgery in a case series of 62 consecutive eyes in patients with no ocular or systemic comorbidity. The patients were followed-up at fixed intervals of one...

Importing iron to the retina

In the retina, iron is particularly critical for the visual phototransduction cascade. In the retinal pigment epithelium (RPE), RPE65 activity leads to 11-cis-retinaldehyde, the photosensitive component of rhodopsin production and iron containing enzymes are necessary for disc replacement in photoreceptor...

Surgical effect of limited membrane dissection

Strabismus surgery was performed with minimal dissection of Tenons sheath and minimal tissue manipulation compared to conventional methods for patients with pure horizontal strabismus – to evaluate the effect on surgical outcomes. The study included 54 patients; 52% female. Mean...

A possible biomarker for diabetic retinopathy

Diabetic retinopathy (DR) is the most common form of diabetic eye disease, characterised by exudates, microaneurysms and haemorrhage. Early diagnosis is crucial for preventing visual loss. The risk of developing diabetic retinopathy is known to increase with age as well...

Does Acanthamoeba need bacteria to cause keratitis?

An animal study was carried out on 36 rabbits, whose corneas were inoculated with either Acanthamoeba castellanii alone, Pseudomonas aeruginosa alone or both pathogens together after a period of short (two hours) or long (six hours) co-incubation. The clinical severity...
