Extraocular muscle OCT

The goal was to evaluate the use of the Heidelberg anterior segment optical coherence tomography (AS-OCT) to image extraocular rectus muscle insertions and to expand the use of the AS-OCT to also image vertical rectus muscles. The authors evaluated inter...

OCT imaging of occluded puncta

This is a description of the use of enhanced depth optical coherence tomography (OCT) to see whether a patent ampulla or canaliculus is detectable in patients with absent or occluded puncta. Nine occluded puncta of six patients with epiphora were...

Laser speckle contrast imaging (LSCI) enables perfusion monitoring of the anterior segment during strabismus surgery: a study on the horizontal rectus muscles

Forty-four eyes with horizontal strabismus surgery involving medial and / or lateral rectus muscle detachment were recruited. The perfusion in the adjacent paralimbal and iris tissue was monitored with LSCI technique, by using a PeriCam PSI NR System. An infrared...

Silent keratitis in failed graft

This study examined rates of asymptomatic keratitis in failed full thickness corneal grafts, which were not picked up clinically preoperatively. During a five year period 53 penetrating keratoplasties (PK) were performed for long-standing graft decompensation with stromal opacity and /...

Vici syndrome

Vici syndrome is a condition associated with agenesis of the corpus callosum, congenital cataract, incomplete albinism, ± immunodeficiency and cardiomyopathy. Individuals show profound hypotony and severe neuro abnormalities. This paper reports a case of Vici syndrome. A 38-month-old female had...

Viral uveitis

This review covers viral causes of anterior uveitis. A viral aetiology should be suspected when anterior uveitis is accompanied by ocular hypertension, diffuse stellate keratic precipitates or the presence of iris atrophy. Most common viruses associated are herpes simplex, varicella-zoster...

A novel parameter for angle closure

This is a population cross-sectional study of 464 eyes that underwent swept-source optical coherence tomography (SSOCT) imaging in the dark. Eight out of 128 cross-sectional images were selected for analysis. Matlab was used to measure the iridolenticular contact area (ILCA),...

The management of chronic central serous chorioretinopathy

Central serous chorioretinopathy (CSCR) is a common retinal disease characterised by one or more serous neurosensory detachments. Patients present with acute onset blurring of vision, metamorphopsia and / or central scotomas. The condition is six times more common in men...

Real-world experience and outcomes of SLT laser used as a first-line treatment in ocular hypertension patients in a United Kingdom National Health Service setting

The management of raised intraocular pressure (IOP) in the context of ocular hypertension (OHT) and primary open angle glaucoma (POAG) remains a major contributor to the workload of ophthalmology units across the UK. Treatment of these conditions has historically centred...

Neovascular AMD: fresh recommendations underline standards of best practice

The management of neovascular age-related macular degeneration (nAMD) has advanced dramatically over the past seven years, with the introduction of targeted new therapies that successfully maintain or improve vision in a majority of affected individuals. It’s a fast moving field,...

Surgical correction of involutional lower lid entropion

This is a retrospective comparative study. The authors analyse results of 281 eyelids with involutional entropion operated by two surgeons, 89 treated with buried resorbable imbricating sutures and 192 with non-buried non-resorbable sutures. The horizontal lid laxity was corrected by...

Review of IDeX surgical outcome measures

The authors aimed to evaluate whether or not there exists standardisation of outcome measures amongst studies in the literature reporting results of surgery for intermittent exotropia. A 10 year literature review was conducted from 2002-2012 with extraction of English language...
