Retinal vessel diameter in pseudoexfoliation

Pseudoexfolation (PEX) is characterised by deposition of fibrillary extracellular material on ocular and extraocular tissue. Studies have shown that deposition in vascular structures cause hypoxia and ischaemia. In the eye, a decrease in blood supply to the optic nerve can...

Transsynaptic retrograde degeneration linked to homonymous visual field loss after stroke

centre, of individuals identified with homonymous visual field loss post ischaemic stroke. Exclusion criteria were bilateral ischaemia, anterior / pregeniculate visual pathway affected and other pathology with the potential to effect visual fields. The following were extracted from the medical...

Positive diagnosis of acute posterior ischaemic optic nerve neuropathy

Posterior ischaemic optic neuropathy is a rare cause of visual loss believed to be due to infarction in the territory of the pial branches of the ophthalmic artery. There is an absence of clinical signs which means the diagnosis is...

The management of retinal vein occlusions: a summary

G-CSF intravitreal injections for NAION: a pilot study

In rodent models with anterior ischemic optic neuropathy (AION), granulocyte colony-stimulating factor (G-CSF) confers a neuroprotective effect on retinal ganglion cells (RGCs) via anti-apoptotic and anti-inflammatory processes. This prospective study investigated the efficacy of intravitreal injection of G-CSF for the...

Better outcomes from early repair of Type B blow-out fractures

This paper examines whether early, rather than late, surgical repair results in better motility outcomes for a particular subgroup of orbital floor blowout fractures. The authors divide floor fractures into Types A and B, depending on whether or not the...

Isolated trochlear (fourth cranial) nerve palsy in an Asian population

The authors report on 35 consecutive new cases of isolated fourth cranial nerve palsy seen over a period of six months in one neuro-ophthalmology clinic in Southeast Asia, with emphasis on their aetiology and management. We report on 35 patients...

How common is optic disc drusen in young patients with NAION?

A retrospective notes review at two tertiary care centres was completed between 2009 and 2019. The inclusion criteria for the study was a diagnosis of nonarteritic anterior ischaemic optic neuropathy (NAION) in at least one eye, aged between 18 and...

Risk factors for non-arteritic ischaemic optic neuropathy in an Asian population

The authors reviewed the medical records of 45 Korean patients with non-arteritic anterior ischaemic optic neuropathy (NAION) and 45 healthy controls, in order to determine risk factors for the condition in an Asian population. Previous studies looking at risk factors...

Occult central retinal artery occlusion

Central retinal artery occlusion (CRAO) is a sight-threatening condition resulting from occlusion of the central retinal artery and hypoperfusion of the inner retina. Early on, fundal examination may be normal. The authors present a retrospective case series of 11 patients...

Risk factors and management for postoperative complications in strabismus surgery

This retrospective cohort study examined 1273 patients, comprising 1035 cases of exotropia and 238 cases of esotropia, with a minimum 18-month follow-up after strabismus surgery. Baseline demographics, age at surgery, pre / postoperative visual acuity, and deviation were included. Complications...

Screening for Sickle Cell Retinopathy (SCR): Why we do wide-field imaging, OCT/OCT-A for SCR – Newcastle upon Tyne Hospitals NHS Foundation Trust

I have been working in ophthalmology for over five years as a photographer and research co-ordinator, and it is fascinating, rewarding, and interesting to learn all about the different diseases associated with the eye. One condition that has been a...
