Optic nerve swelling – your survival guide (part 2)

In this second article we will discuss bilateral optic nerve swelling, its aetiology, various investigations and possible treatments. We will also discuss various protocols used in the management of suspected optic nerve swelling cases. (Part one of this topic available...

Saving sight and changing lives: working with Syrian refugees in Jordan

Two ophthalmologists from the Emory Eye Center share their three-year experience of treating refugees in the camps in Jordan. Jordan currently hosts an estimated 1.4 million Syrian people who have fled the war in their home country. Cataract & Cornea...

Thinking outside the box – adapting to the COVID-19 lockdown

How can we avoid further delays to follow-up in glaucoma patients? The author asks if there is a socially distanced way to check IOPs in those at high risk of losing vision. Glaucoma is an asymptomatic condition. Loss of the...

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...

Cataract in patients with pseudoexfoliation syndrome

The authors present a prospective comparative study in 43 patients with (group 1) or without (group 2) pseudoexfoliation (PXF) undergoing cataract surgery. Anterior capsule samples were obtained in all patients and analysed for signs of apoptosis by using special staining...

MicroRNA inhibits corneal neovascularisation

MicroRNAs (miR) are small non-coding RNA that target mRNA for destruction. MiR target about 30% of the protein coding genes and fine tune their expression. MiR have been shown to be involved in several cellular processes including cell cycle, tissue...

Statins inhibit TGFβ2 mediated fibrotic response in astrocytes

Glaucoma is a common condition where increased ocular pressure can lead to death of retinal ganglion cells due to impaired drainage of fluid from the eye. One mechanism involved in glaucoma is remodelling of the extracellular matrix at the lamina...

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...

Bilateral internuclear ophthalmoplegia

Bilateral internuclear ophthalmoplegia (INO) has been linked with various pathological conditions of the central nervous system such as multiple sclerosis, stroke, tumours and brainstem inflammatory processes. This unusual case report describes a case of a 45-year-old female patient presenting with...

MicroRNAs in cataract

In an ageing population cataract formation is one of the leading causes of blindness. Cataracts are caused by a failure to clear accumulating aggregated proteins in the lens. MicroRNAs are small non-coding transcripts which bind to specific mRNAs acting at...

Enzymatic clearance of anterior chamber infiltrate in uveitis

Aqueous humour (AH) which fills the anterior chamber (AC) of the eye provides nutrients to the cornea and the lens. Clearance of cellular and particular matter from AH is necessary for good visual acuity. In part this is achieved by...

Emergency, Acute and Rapid Access Ophthalmology

There are two parts to the book; the first section makes up the bulk to the textbook and covers clinical aspects of emergency ophthalmology, and the second discusses the management and organisation of an emergency and rapid access service. Part...
