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...

Pseudophakic Monovision: A Clinical Guide

The contents of this small volume should provide useful tips for all ophthalmic practitioners involved with managing patients undergoing cataract surgery. For those ophthalmic clinicians and supporting staff not familiar with the potential options for achieving a spectacle independent refractive...

Two bifocals and a trifocal

The authors compare the optical outcomes of two bifocal intraocular lenses (AcrySof ReSTOR +2.50 Diopter [D] add +3.0D add) with a trifocal lens (AT LISA tri 839MP). The optical qualities of the lenses were quantified by measuring the modulation transfer...

Biometry measure after cycloplegia

The authors investigated optical biometry in an Indian paediatric population on normal and cataract paediatric eyes and studied the effect of cycloplegia on different parameters measured in these eyes. This was a prospective study of 76 eyes aged five to...

Disc margin delineation using spectral domain OCT

Observing progressive anatomical changes of the optic nerve head is essential in the detection of progression in glaucoma. Imaging devices continue to evolve and are useful in detecting change in established glaucoma, although probably less useful in an initial diagnosis....

Visual fields and OCT in hydroxychloroquine retinopathy

It has been recommended that patients on hydroxychloroquine be monitored regularly for retinopathy. However, there has not been an agreement as to the best screening test for hydroxychloroquine toxicity, which may include visual fields (VF), fundus autofluorescence, spectral domain optical...

Metamorphopsia in idiopathic epiretinal membranes

The Amsler grid is commonly used for self-monitoring, but is qualitative and has low sensitivity. The M-chart reduces the amount of spatial redundancy (‘filling in’) in the Amsler grid. The Orientation Discrimination (OD) test studied in this paper consists of...

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...

MRI characteristics of NMO, MOG and MS-related ON

This review article examined differences of MRI appearances that can help clinicians assess and manage these important neuro-ophthalmic disorders. It also examined the role of optic nerve MRI as a prognostic indicator in acute optic neuritis (ON). The major findings...

Clinical Observation Days Pave Way for Next Generation of Optometrists

Optometry students at Glasgow Caledonian University have taken part in a series of clinical observation days at one of the UK’s leading eye surgery clinics, as part of a new programme giving student optometrists experience of modern day surgical practice.

Safe cataract extraction with underlying hypotonous cilio-choroidal detachment following trabeculectomy surgery

The authors of this study (including the reviewer of this article) describe a surgical technique for phacoemulsification in the presence of shallow choroidal detachment owing to hypotony following trabeculectomy. In their case series, four eyes of four patients with advanced...

OCT in peripheral corneal thinning

This small retrospective study used high resolution optical coherence tomography (OCT) Heidelberg Spectralis to identify features which could determine the underlying aetiology of peripheral corneal thinning. Ten patients were included; five with diagnoses of degenerative peripheral thinning; Terrien’s marginal degeneration...
