Optic disc pit maculopathy: an optical coherence tomography study

This was a single-centre, retrospective observational case series that aimed to analyse the change of optical coherence tomography (OCT) characteristics in the natural course of optic disc pit maculopathy (ODP-M) and their effects on visual acuity. Twenty-two eyes of 22...

The prevalence of macular cysts in patients with clinical cone-rod dystrophy determined by spectral domain optical coherence tomography

Cone-rod dystrophy is a progressive photoreceptor disorder which has multiple inheritance patterns. It is rare, with a prevalence of 1 in 40,000. Macular cysts are well recognised in other photoreceptor conditions such as retinitis pigments and choroideraemia, while they are...

The history, evolution and future of optical coherence tomography

OCT has made it possible to capture a detailed 3D image of the retina, revolutionising ophthalmic diagnostics and optometric practice. Professor Fujimoto, inventor of OCT, visits us from MIT to speak on the transformative impact of OCT and its future role in AI diagnostics, vision and wider healthcare.

GREG: Optical Coherence Tomography (OCT) Qualifications – March 2025 cohort application deadline

Gloucestershire Research & Education Group in Partnership with the University of Gloucestershire are pleased to provide both the Cert HE in OCT Capture and the Uni Dip in OCT Interpretation. The deadline for the March 2025 cohort applications is 24th January 2025. These qualifications have been designed to meet the needs of routine operators of OCT equipment and interpreters of OCT scans. For further information visit www.gregcourses.com

Normal values with Orbscan IIz corneal topography

This study aimed to establish a database of normative measurements of corneal typography in children aged 5-15 years with the Orbscan IIz corneal topography system. They assessed 100 eyes of 100 children. The mean SimK astigmatism was 0.69±0.35D. The maximum...

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...

Effect of phacoemulsification on facility of outflow

This is a prospective study to examine the change in electronic Schotz tonographic outflow (TOF) and IOP measurements after phacoemulsification. Intraocular pressure was measured using Goldman‘s applanation tonography (GAT). Data were collected at baseline, three, six and 12 months postoperatively....

Keratoconus: When, Why and Why Not. A Step by Step Systematic Approach

This is a single author publication addressing the subject of ectatic corneal disorders and keratoconus (when, why, and why not) with a step by step systematic approach to management using modern sophisticated diagnostic and screening tools. It is comprised of...

Multimodal Retinal Imaging

Understanding of rapidly advancing retinal imaging techniques is important as they have changed the management of retinal conditions considerably. Interpretation of these tests is a vital skill in the armamentarium of every practising ophthalmologist. The book is directed at general...

Image Analysis and Modelling in Ophthalmology

Recent advances have revolutionised ophthalmic imaging and helped understand the pathophysiology of ocular diseases and thus help in the diagnosis and management of ocular diseases. The authors of this book have gone through most of the available imaging techniques available...

BESTi: a new index to detect subclinical keratoconus

In this multicentre, case-control study, the authors develop a new index, named Boosted Ectasia Susceptibility Tomography Index (BESTi), to detect early cases of keratoconus. This index was derived from multiple logistic regression analysis of 22 variables of tomography scans. The...
