Reducing postop nausea and vomiting

This study adopted an aggressive prophylactic anti postoperative nausea and vomiting (PONV) regime with retrospective review of patient outcomes. Of 794 adult strabismus procedures, 31 (4%) had PONV. Median post-anaesthetic recovery was 45 minutes. Prolonged recovery was associated with long-term...

The natural history of treatment naïve choroidal neovascularisation (CNV) in geographic atrophy

The aim of this retrospective study is to assess the characteristics and natural history of quiescent CNV in geographic atrophy (GA) utilising multi-modal imaging. Case notes were reviewed of patients diagnosed with geographic atrophy between January 2010 and December 2016...

ANGPTL-4 inhibition reduces inflammation in diabetic retinopathy

Diabetic retinopathy (DR) is the most common cause of blindness in working-age humans, and numbers are rising due to increased cases of type 2 diabetes (T2D). T2D is associated with increased obesity and dyslipidaemia, which is a major risk factor...

The fragile p-value

Abdus Samad Ansari explores the limitation of the p-value and the application of the fragility index in clinical trials. Clinical trials and tribulations? The restoration of vision or more purely the gift of sight is an aspect of care that...

A brief history of colour vision

Andrew Want takes a look at how colour vision has evolved in humans and animals and how it differs across species. Colour vision is something that we often take for granted, but it has become so intrinsic to the way...

#KnowYourDrops: breaking down barriers to poor compliance

Award-winning* #KnowYourDrops eye drop compliance campaign helps patients for World Glaucoma Week to achieve medicines optimisation in ophthalmology. The #KnowYourDrops campaign is fast becoming an internationally recognised model to help support healthcare professionals, with the provision of better tailored ophthalmic...

The role of spectral-domain OCT RNFL in revealing a pituitary adenoma with atypical visual fields

Pituitary adenomas classically cause bitemporal hemianopia by compressing the optic chiasm. However, in some cases, the pattern of visual field loss may be atypical and mimic homonymous hemianopia, depending on the direction and extent of tumour expansion. Spectral-domain optical coherence...

*Please be aware that this data does not form part of a peer reviewed research study. The information therein should not be relied upon for clinical purposes but instead used as a guide for clinical practice and reflection. The sample...

Anti-VEGF injections and macular atrophy progression in patients with nAMD in remission

This is a retrospective study of 59 eyes with neovascuar age-related macular degeneration (nAMD) with at least 6-month remission, to determine the effect of continuing anti-VEGF injections on the progression of macular atrophy (MA) during remission of nAMD. Group 1...

Shifting the paradigm of managing patients in medical retina: how real-world data can help us to improve clinical practice

The ophthalmic subspecialty of ‘medical retina’ has undergone dramatic changes in recent years. With the introduction of ranibizumab (Lucentis, Novartis), a specialty formerly dominated by laser-based therapies has been transformed to become, in large part, pharmacotherapy-based. To date, these pharmacotherapies...

Effects of topical anaesthetic on intraocular pressure

This prospective interventional study assessed the effects of repeated intraocular pressure (IOP) using Goldmann applanation tonometry and applanation resonance tonometry in six volunteers. Previous literature supports IOP reduction using repeated applanation tonometry. Repeated IOP measures were taken alternately on 12...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...
