Swept-source OCT for measuring peripheral anterior synechiae

The authors report on a cross-sectional study looking at swept-source optical coherence tomography (SS-OCT) for measuring the area and degree of peripheral anterior synechiae (PAS) in patients with angle closure glaucoma. The SS-OCT is commercially available, has a laser wavelength...

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...

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),...

Comparison of bleb grading and IOPs

The purpose of this study was to compare a novel anterior segment optical coherence tomography (AS-OCT) bleb grading system with a clinical bleb grading system (Moorfields) and both with intraocular pressure (IOP) levels following trabeculectomy surgery. The authors developed a...

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...

Changes in Japanese eyes after laser peripheral iridotomy

The aim of this study was to evaluate laser peripheral iridotomy (LPI) induced changes in anterior segment parameters, using the anterior segment optical coherence tomography (ASOCT). Seventy-two subjects of Japanese ethnicity with primary angle closure suspect (PACS), primary angle closure...

Cortical blindness

Cortical blindness is a rare but recognised entity. Cerebrovascular accident is a well-known risk factor. We report a case of an 84-year-old lady with bilateral cortical blindness with multiple cardiovascular risk factors. Case report An 84-year-old lady was admitted under...

Amblyopia OCT results

The authors compared the macular and peripapillary retinal nerve fibre layer (RNFL) thicknesses of amblyopic and fellow eyes using Stratus optical coherence tomography (OCT) to reveal any differences. They sought to determine the anatomical differences between these subtypes of strabismic...

The treachery of images – making sense of OCT imaging

In 1929 Belgian surrealist Rene Magritte produced his painting La Trahison des Images. It depicted an old fashioned pipe for smoking tobacco and underneath were the words “ceci n’est pas une pipe”, this is not a pipe. You may wonder...

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...

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...
