Nanofiber-based hydrogels prevent capsular opacification

Lens refilling is the replacement of the lens with a silicone polymer in an otherwise intact lens capsule. However, capsular opacification (CO), resulting in reduced visual acuity, is a major complication of these injectable accommodating lenses. Opacification is due to...

Dry eyes after photorefractive keratoplasty

This study examined changes in tear break up time (TBUT), Schirmer test, tear osmolarity and dry eye questionnaire (OSDI) score from prior to photorefractive keratoplasty (PRK), to two months and four months postoperatively. Fifty eyes of 25 patients were examined....

DALK as an early therapeutic option for Acanthamoeba keratitis

Eleven patients with Acanthamoeba keratitis (AK) were treated by early therapeutic deep anterior lamellar keratoplasty (DALK). All surgeries were performed in patients who had no response to standard medical therapy of chlorhexidine gluconate, propamidine isethionate and neomycin sulphate, within 10-15...

Somatostatin protects retinal pericytes

Diabetic retinopathy (DR) is a complication of diabetes, caused by high blood sugar levels damaging the retinal microvasculature. Mechanisms, such as oxidative stress and deposition of advanced glycation end products, leads to glial cell activation and neuronal apoptosis. Pericytes, contractile...

Akimba mice, a model of human diabetic retinopathy

Diabetic retinopathy (DR) is a major complication of diabetes and a growing problem as the systemic disease becomes more prevalent. DR develops insidiously from an asymptomatic form through to vascular damage that leads to oedema and breakdown of the blood-retinal...

Management of restrictive diplopia after ptergium surgery

This single centre retrospective case series included 15 patients with restrictive diplopia after ptergium excision. The mean time from surgery to diplopia was six months and all patients had a moderate limitation of abduction in the operated eye causing an...

Orbital cavernous haemangiomas

This is a review of orbital cavernous haemangiomas (orbital cavernous venous malformations) managed over a 12-year period at a tertiary referral centre. Painless proptosis was the commonest presentation. One hundred and sixty-four patients (96 female and 68 male) underwent surgery...

How to reconstruct an upper lid defect

In this 10-year review, the authors look at published techniques for repairing upper lid defects and their respective success. Of the 10 studies included in this paper, they divide the techniques described within to bridging and non-bridging. Bridging techniques tend...

Features and outcomes of pulled-in-two syndrome

Pulled-in-two (PIT) syndrome is a sudden rupture of the extraocular muscle during strabismus surgery, typically with minimal tension intraoperatively without excessive force. This is a rare occurrence and this study reports cases from a single centre over a seven-year period....

The Duke-Elder exam: A medical student’s head start into ophthalmology

The Duke-Elder exam is a specialist ophthalmology exam intended for medical students to sit during medical school. It is named after Sir Stewart Duke-Elder, a pioneering Scottish ophthalmologist who was active in the first half of the 20th Century by...

Nurse-led Rapid Corneal Collagen Cross-linking / UKISOP Society Education Day

Nurse-led Rapid Corneal Collagen Cross-linking By Dan Gore Over the last decade, clinical trial data has accumulated for new interventions in keratoconus that promise to arrest disease progression, significantly reduce transplantation rates and save many patients from long-term reliance on...

Is laser refractive surgery safe for patients taking isotretinoin?

This multicentre, retrospective, interventional case series assesses the outcomes of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) in 113 patients taking isotretinoin between January 2003 and September 2017. Isotretinoin is contraindicated for LASIK and PRK and patients are...
