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...

Retrospective safety assessment of apraclonidine for diagnosis of Horner’s syndrome in children

Apraclonidine has been shown to reverse the anisocoria in Horner’s syndrome, with some reports of partial ptosis resolution. Side-effects of apraclonidine have been reported especially in children under six months old. The authors present a retrospective safety study of using...

Recurrent corneal erosions secondary to isotretinoin use

Isotretinoin (13–cis-retinoic acid) is the first line treatment for moderate to severe nodulocystic or papulopustular acne [1,2]. Although it is a safe medication, it has several adverse side-effects, including ophthalmic manifestations, as shown in Table 1 [3]. These side-effects need...

Forward-tilt technique for intraocular pressure measurement in upgaze

The authors suggest a technique to improve the accuracy of measuring IOP in upgaze using Goldmann applanation tonometry. Graves’ ophthalmopathy, also known as thyroid eye disease, is an autoimmune inflammatory condition affecting the orbit and periorbital tissues [1]. It was...

Ophthalmic mentors: In conversation with Professor Harminder Dua

In the first of a series of interviews with key figures in the world of ophthalmology, Eye News speaks to Professor Harminder Dua about the future of clinical academia, his recent College presidency and Dua’s Layer. Professor Harminder Dua is...

Comparing femtosecond laser assisted-DMEK to manual DMEK

Femtosecond laser is as a novel tool for performing precise descemetorhexis in descemet membrane endothelial keratoplasty (DMEK) surgery. In DMEK surgery, the recipient’s Descemet membrane is peeled to allow adherence of the donor DMEK tissue to the recipient’s stroma. Complete...

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...

Combined PRK and CXL in keratoconus

This study aimed to investigate the results after photorefractive keratectomy (PRK) followed immediately by standard 30-minute corneal cross-linking (CXL) for keratoconus. This retrospective study included 26 eyes of 16 patients with keratoconus. Uncorrected distance visual acuity (UDVA), corrected distance visual...

Sexually transmitted conjunctivitis – the REALLY sticky eye

Let’s face it, patients with conjunctivitis don’t always produce the most stimulating consultations and most of the time we can manage them in auto-pilot. The prospect of delving into such a patient’s sexual history is not overly appealing, but this...

Limbal melanocytes and the stem cell niche

The cornea is continually regenerated to maintain clear vision, due to a population of stem cells located in the limbal region between the cornea and the conjunctiva. These limbal stem cells (LESC) reside in crypts in structures called the Pallisades...

Life’s rich tapestry

Have you ever watched someone cross-stitch, or do needle-point? I recently had the joy of observing my teenage daughter create such an artwork. She separated all the threads into the various colours, and then started to follow the instructions carefully....

The embryology of the eye

Nobody claims to like embryology. At least nobody I know. It has been a neglected part of the curriculum since time immemorial and a vicious cycle occurs in which those with an incomplete understanding fail to appreciate the inherent beauty...
