Multimodal imaging in wet AMD

This novel study set out to determine grader agreement levels of various retinal imaging techniques, commonly used in the diagnosis of wet age-related macular degeneration (AMD). Images from 52 eyes were by examined by two different observers. All images were...

Anterior segment OCT imaging in cases of episcleritis and scleritis

The purpose of this study was to determine whether it is feasible to obtain good-quality images with anterior segment OCT (AS-OCT) in patients with episcleral or scleral inflammation located anterior to the equator, and whether this technique is able to...

Take part in the 'Whole Eye OCT Experience' at 100% Optical 2024

The Whole Eye OCT Experience is being delivered in association with The Partially Sighted Society: a charity that helps anybody living with vision loss make the best use of their remaining vision.

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...

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....

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...

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...

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.

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...

Handbook of Pediatric Retinal OCT and the Eye-Brain Connection

Paediatric optical coherence tomography (OCT) imaging of the eye remains an evolving technology to date. This handbook delves into this challenging area successfully and gives a comprehensive and detailed input into paediatric OCT pertaining to the retina and the optic...

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...
