The ocular manifestations of COVID-19: an overview of current literature

Although respiratory symptoms are the most frequent manifestation of COVID-19, multi-organ involvement has been demonstrated, including ocular manifestations. The author investigates how the eye can be affected. The SARS-CoV-2 virus responsible for the COVID-19 pandemic has presented a significant public...

Visual disturbance heralding stroke: are we seeing the signs in time?

Isolated visual symptoms may be an early presenting feature of stroke, and timely recognition of such atypical cases is important because treatment for stroke has a limited time-window of efficacy. Stroke occurs in approximately 150,000 people per year in the...

The ROP Network: a south-south collaboration to improve care for premature babies

Retinopathy of prematurity (ROP) is a disorder of the immature preterm retina and a leading cause of preventable, irreversible blindness in children. There are 15 million preterm births annually, and over 32,000 neonates became blind from ROP in 2010 [1]....

The Duke-Elder Undergraduate Prize Exam is a competitive exam aimed at undergraduates with an interest in ophthalmology. It is amongst the most prestigious undergraduate prizes in the United Kingdom. I would encourage motivated candidates to get their hands on as...

Biopsy of nasolacrimal duct using sheath guided dacryoendoscopy

In this study the author’s biopsied six eyes of five individuals with recurrent nasolacrimal duct obstruction following a prior dacryoendoscopic probing. All procedures were performed under local anaesthetic, the obstruction or lesion was directly visualised with dacryoendoscope and biopsy was...

Consecutive exotropia features

This study sought to detect abnormal scleral attachment with comparison of histopathological findings in consecutive exotropia. The study also considered the success rate of medial rectus resection and advancement, dose response and evaluate potential preoperative factors that might indicate presence...

Laser pointer maculopathy

The objective of this study was to describe the potential clinical presentations of retinal pathology resulting from exposure to laser pointers. The study included eight eyes of seven patients. Mean age was 18.7 years (12-36). Most were accidental self-inflicted while...

OCT-A imaging in Grave’s orbitopathy and orbital decompression

In this case series of 12 patients and 24 orbits, the authors describe the changes in the optic nerve and peripapillary blood vessel density in patients with moderate to severe Grave’s Orbitopathy (GO) undergoing orbital decompression. The patients undergoing orbital...

Investigating the effect of signal strength on mean retinal nerve fibre layer

The aim of this study was to determine the effect of signal strength on mean retinal nerve fibre layer (RNFL) using spectralis optical coherence tomography (S-OCT). Thirty normal subjects were imaged with S-OCT using variably dense Bangerter foils to alter...

Online retinoblastoma surveillance tool

Given the vision and life-threatening course of retinoblastoma (RB), it has become a significant heritable childhood cancer to screen for. To recommend surveillance, risk must be estimated and genetic testing plays a vital role. However, genetic tests vary based on...

Using optical coherence tomography angiography to detect MoyaMoya vasculopathy
