OCTA FAZ measurements in vein occlusion

Previous studies have confirmed that foveal avascular zone (FAZ) enlargement is correlated with visual acuity impairment in patients with retinal vein occlusion (RVO). This current study aimed to evaluate the OCT angiography parameters: the area of FAZ, foveal and parafoveal...

OCTA and pigment epithelium detachments

Yannuzzi et al. report on their study aiming to evaluate the ability of optical coherence tomography angiography (OCTA) to differentiate vascularised from nonvascularised pigment epithelium detachments (PEDs) using conventional imaging techniques, including fundus fluorescein angiography (FFA) and indocyanine green (ICG),...

Does Ozurdex affect perfusion status in vein occlusion?

Ozurdex (intravitreal dexamethasone implant) has been approved by National Institute of Health & Care Excellence (NICE) for treatment of patients with macular oedema associated with vein occlusion. This study looks at the change in peripheral perfusion status in patients with...

OCTA in angioid streaks

This paper reports on the optical coherence tomography angiography (OCTA) features of choroidal neovascularisation (CNV) secondary to angioid streaks and the ability to predict CNV activity. A total of 38 eyes of 19 patients were included in the study. Thirty...

Comparison between findings in OCTA and FA in patients with diabetic retinopathy

In this study the authors present a prospective cross-sectional comparative study of typical findings of diabetic retinopathy to analyse the agreement between the image modalities of optical coherence tomography angiography (OCTA) and fluorescein angiography (FA). Fifty-three eyes of 42 patients...

Clinical relevance of the anatomic classification of neovascular age-related macular degeneration

The author explains why an OCT-based classification of neovascular AMD is needed and how these neovascular subtypes may help to predict patients’ long-term visual outcome. Age-related macular degeneration (AMD) is a chronic and progressive neurodegenerative process involving the macula in...

Vitreoretinal Disease: Diagnosis, Management and Clinical Pearls (second edition)

A comprehensive, well-illustrated and highly informative resource providing excellent descriptions of vitreoretinal diseases, their presentation, diagnosis and management. The 40 chapters are grouped into four sections, namely: the Anatomy and Physiology of the vitreous, retina, choroid and retinal pigment epithelium;...

OCTA use in CNV associated with CSR

The aim of this study was to assess the rate of choroidal neovascularisation (CNV) in chronic central serous chorioretinopathy (CSR) patients with flat irregular pigment epithelial detachments (PEDs) by optical coherence tomography angiography (OCTA). Data of all consecutive patients with...

RetCam use in differential diagnosis for retinoblastoma

The authors aimed to evaluate RetCam fundus photography and fluorescein angiography (FA) findings in pseudo retinoblastoma. This was a retrospective review of 36 eyes of 28 patients (of which six were female) with 22 bilateral cases. Mean age at presentation...

Cataract surgery and circadian photoentrainment

The study authors sought to investigate the possible effects of circadian photoentrainment following cataract. This was a randomised clinical trial, where 76 eyes of 76 patients (with bilateral cataract) were randomised to blue-blocking or neutral intraocular lenses (IOLs). Outcome measures...

Essentials of OCT in Ocular Disease

Sir Isaac Newton was the first to establish the technique of low coherence white light interferometry. Following on from this, the principle of laser interferometry as an imaging modality for retina was applied by David Huang and his associates in...

The Retinal Atlas (2nd Edition)

Those readers familiar with the first edition of The Retinal Atlas will appreciate the comprehensive nature of this publication, and this latest version incorporates retinal images generated by recently developed imaging technology. As the title suggests, this hardcover version is...
