Corneal crosslinking in pellucid marginal degeneration
Fourteen studies were included in this first review examining the use of corneal-crosslinking (CXL) to treat pellucid marginal degeneration (PMD). PMD is a bilateral, non-inflammatory corneal thinning disorder characterised by inferior peripheral corneal thinning 1-3mm from the limbus in the...
Sex hormones in males and females with central serous chorioretinopathy
This study was aimed to assess the role of sex hormones in male and female patients with central serous chorioretinopathy (CSC), a disease with a pronounced male predilection. Two hundred and six patients, 183 males (mean age 52, median 52,...
Risk factor for surgical failure in consecutive XT
This study was designed to determine the success rate among patients with consecutive exotropia after choosing an appropriate surgical method based on medial rectus function and level of exo deviation. The authors conducted an interventional case series study of 40...Orbis eye health programme integrated into school curriculum in Nepal
Leading eyecare charity Orbis and Nepal’s National Society of Comprehensive Eye Care (NNJS) have worked together since 2019 to implement a programme called REACH (Refractive Error Among Children) in Eastern Nepal.
Dead bag syndrome: a new and rare cause of late IOL dislocation
The dead bag syndrome has recently been described as a cause of late spontaneous intraocular lens (IOL) subluxation and / or dislocation. The capsular bag remains clear years after surgery and then becomes diaphanous and floppy. The authors explanted seven...
Fusional vergence measurement
This paper reports a systematic review to address two objectives: 1, to compare the normative values of tests measuring fusional vergence; 2, to investigate sources of heterogeneity of prism accuracy. The review was conducted according to PRISMA guidelines with a...
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...
IOL power in short eyes
Prospective analysis of 269 eyes of 269 patients between 2017 and 2020, with axial length (AL) of 22mm or less. New principles for calculating IOL power were recently developed, including formulas based on paraxial ray-tracing (Barrett and Olsen) and based...
Comparing tensile strengths of two scleral fixated intraocular lenses: CT-Lucia and MA60
The authors designed a benchtop model to measure the tensile strengths and resistance to breakage of the haptics and haptic-optic junctions of the CT Lucia 602 (Carl Zeiss, California) and AcrySof MA60 (Alcon Laboratories, Texas) IOLs. For the haptic breakage...The challenge of chorioretinal folds in virtual eye clinics
Chorioretinal or choroidal folds are parallel striations involving the retina, retinal pigment epithelium (RPE), Bruch’s membrane, and inner choroid [1]. They can arise from compressive stress on these layers, and their presence often serves as a diagnostic marker for underlying...The Arclight: A ‘pocket’ ophthalmoscope to revitalise undergraduate teaching?
Ophthalmoscopy should be a core skill for every doctor and should be firmly embedded in the undergraduate curriculum similar to the unquestioned position of the stethoscope. The simplicity of the Arclight means it is easy to useand, importantly, to learn...
