Nerve head in healthy humans using OCT-angiography

Optical coherence tomography angiography (OCT-A) is a recent, dyeless, and noninvasive imaging technique for evaluating depth-resolved vascular status by capturing the dynamic motion of the erythrocytes. It provides the flow map of major vessels and capillary plexuses separately in different...

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...

Choroidal and macular thickness in nonarteritic anterior ischaemic optic neuropathy

This study evaluates the choroidal and macular thickness in patients with chronic nonarteritic anterior ischaemic optic neuropathy (NA-AION). Two groups of subjects were compared, group one included 20 eyes with chronic NA-AION and group two, 31 healthy control eyes. The...

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...

A review of neuro and retinal imaging findings in Alzheimer’s disease

The authors present a systematic review with the aim of assessing the relationship between retinal and cerebral changes in Alzheimer’s disease (AD), mild cognitive impairment and pre-clinical AD. A total of 23 articles met the inclusion criteria of the review,...

Meeting the needs of older patients in optics

Fiona Anderson discusses the important role of community-based eyecare practitioners in meeting the visual needs of ageing patients. It has been well documented that today we live for longer. Statistics show in 1997, around one in every six people (15.9%)...

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...

Silmo Academy by the IOA hailed a great success

The first Silmo Academy event by the IOA wrapped up in Singapore this month and it attracted optical professionals, academics and trendsetters from around the world.

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...

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...

Literature review of OKN

The authors conducted a critical review of the optokinetic nystagmus (OKN) literature to consider OKN and in particular, vertical OKN. The review provides an overview of OKN to aid understanding of the eye movements. It provides a review of the...

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...
