An environmentally friendly eye service

A single cataract procedure in the UK has been estimated to have a carbon footprint equivalent to driving a typical non-electric car for 310 miles. Surprisingly, very few centres around the world have worked out the environmental cost of cataract...

How to pass the Refraction Certificate

Unfortunately, I had the pleasure of getting to know this exam intimately. With adequate preparation this does not have to be the case for most people. The exam has recently changed to consist of 10 OSCE style stations (previously 12)....

Photophobia: an unusual symptom of a pituitary macroadenoma

Introduction Photophobia, defined as ‘an abnormal intolerance to light’, is commonly associated with a range of both ocular and neurological pathologies such as dry eye, blepharospasm, corneal pathologies, cataracts, uveitis, retinal dystrophies, optic neuritis, migraine, meningitis, and traumatic brain injury...

Nicotine accelerates diabetes induced retinal changes

This study investigated the influence of nicotine in an experimentally induced diabetic rat model. They used non-invasive high-resolution spectral domain optical coherence tomography (SD-OCT) imaging to provide quantitative information on the temporal alterations of retinal structures at the micrometer resolution...

Ranibizumab for the treatment of age-related macular degeneration

This multicentre randomised prospective open label study compared 0.5 versus 2mg of ranibizumab in patients with submacular retinal pigment epithelial (RPE) detachment due to age-related macular degeneration. Four treatment regimens were used for the two strengths either monthly for 12...

Spectral domain OCT vs. confocal scanning laser ophthalmoscope in measuring RNFL thickness

The aim of this prospective study was to compare the retinal nerve fibre layer thickness (RNFL) measurements obtained from the Cirrus optical coherence tomography (spectral domain OCT) with the Heidelberg Retinal Tomograph 3 (HRT3, confocal scanning laser ophthalmoscope). Eighty-eight normal...

Avastin vs. Volon A for diabetic macular oedema

This prospective randomised interventional clinical trial compared 30 diabetic patients with macular oedema treated with either intravitreal injections of bevacizumab (Avastin) or triamcinolone (Volon A). One group initially received three injections of 2.5 mg Avastin in monthly intervals whilst the...

SLT short-term results

The aim of the study was to evaluate the risk of adverse effects and short-term results after 360 degrees selective laser trabeculoplasty (SLT) in glaucoma patients. The authors enrolled 64 eyes of 64 patients all who had poorly controlled primary...

Clinical and neuro-ophthalmologic predictors of visual outcome in idiopathic intracranial hypertension

This prospective study of 40 patients aims to assess visual morbidity in patients with idiopathic intracranial hypertension (IIH). Final visual outcome of patients was compared with clinical and neuro-ophthalmic parameters such as visual acuity, visual field, contrast sensitivity, retinal nerve...

Visual outcomes, visual fields and optical coherence tomography in paediatric craniopharyngioma

This study reviews the visual outcomes of ten patients under the age of 18 years with craniopharyngioma. The paper also reviews the correlation between visual field (VF) testing and optical coherence tomography (OCT) examination and evaluates the role of OCT...

Lucentis for pseudophakic CMO

Pseudophakic cystoid macular oedema (CMO) develops angiographically in up to 20-30% after uneventful phacoemulsification. This study aimed to evaluate the potential efficacy and safety of intravitreal ranibizumab in patients with pseudophakic CMO after cataract surgery. Seven eyes were included in...

Effect of refractive corneal surgery on IOP and glaucoma progression

Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...
