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...
Risk of developing pseudotumor cerebri in women using a levonorgesteral intrauterine device
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...
Diagnostic accuracy of different keratoconus detection indices of pentacam in paediatric eyes
This is a retrospective study of 432 non-keratoconic eyes compared with 48 eyes with keratoconus (KC) or forme fruste KC (FFKC) in a paediatric population in Cairo, Egypt between December 2013 and October 2018. The authors discuss the rationale of...
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)....
How many injections in nAMD: ranibizumab vs. aflibercept
Intravitreal anti-VEGF injections make up a large proportion of the workload in ophthalmology clinics. Since the introduction of aflibercept with eight weekly injections there has been an option to use a treatment which may require less treatment, with potential cost...
