Beware the disc in myopic patients

Glaucoma is a chronic and progressive optic neuropathy characterised by damage of retinal ganglion cells. Evaluation of structural damage of the optic nerve is important in glaucoma diagnosis. The ISNT rule states that the neuroretinal rim width is generally widest...

A day in the life of...an ophthalmic imager / an orthoptic assistant

The ophthalmic imager My role as an ophthalmic / medical photographer has evolved, dramatically, since I began my career at Manchester Royal Eye Hospital, 30 years ago. Long gone are the days of developing and hand printing fluorescein angiograms in...

Anterior segment OCT predicts gonioscopic angle closure

This is a prospective observational study of 342 subjects over four years. Sixty-five were controls who had open angles both on gonioscopy and AS-OCT, while 277 had open angles only on gonioscopy but iridotrabecular contact (ITC) on AS-OCT (one to...

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...

OCT in microtropia

The aim of this study was to assess whether OCT could be useful in detecting and documenting fixation in children with microtropia. The study used spectral domain OCT (Cirrus) in 15 patients (10 female, five male) and 10 control eyes....

Updated staging of LCHADD retinopathy

The authors present their proposal for an updated staging system for Long-Chain 3-Hydroxyacyl-CoA Dehydrogenase (LCHAD) deficiency retinopathy. This is a rare mitochondrial disease due to deficiency of the long chain fatty acid oxidation pathway. Forty patients who were part of...

New report calls for national funding to expand life-changing eye care technology

Optometry Scotland warns of “postcode lottery” Optometry Scotland (OS), the representative body for optical professionals, has published a landmark report calling for the full integration of an early diagnostic tool in primary eyecare across Scotland. Ocular Coherence Tomography (OCT) is...

Imaging findings for macular dysplasia in nystagmus

This paper reports the retrospective analysis of congenital macular dysplasia in patients with albinism, macular heterotopias, congenital aniridia, foveal hypoplasia, congenital macular coloboma and congenital retinoschisis. The study included 29 eyes of 17 patients. The authors report SD-OCT aids diagnosis...

Detecting glaucoma with only OCT

In this review article, the authors describe a probability model based upon only OCT to detect glaucoma. They explain how normal anatomical variation can lead to false positives and applying a model to account for this improves specificity. The application...

Appeal for fundus cameras and OCT machines for Nigeria

Nigeria has the highest population of people living with diabetes mellitus (DM) in sub-Saharan Africa. As at 2013 the population of people living with DM stood at 4.9 million, of whom an estimated 1.7 million had diabetic retinopathy (DR). There is currently no national DR screening and treatment programme.

Macula re-attachment following intravitreal ranibizumab in rhegmatogenous retinal detachment

Ranibizumab (Lucentis) is a vascular endothelial growth factor inhibitor (anti-VEGF) used for treatment of choroidal neovascular membrane [1]. We report a case where macula off inferior rhegmatogenous retinal detachment was misdiagnosed as wet age-related macular degeneration (AMD) and three intravitreal...

The Leicester Grading System for Foveal Hypoplasia

The University of Leicester Ulverscroft Eye Unit have published the first medical grading system named after the city of Leicester. Infantile nystagmus is characterised by constant and involuntary eye movements and affects 24 per 10,000 people [1]. Onset is usually...
