Retina / Uvea / Vitreous
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...

Retina / Uvea / Vitreous
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

Glaucoma
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

Retina / Uvea / Vitreous
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...

Retina / Uvea / Vitreous
During pregnancy there can be different types of ocular changes including a decrease in corneal sensitivity, increase in central corneal thickness and curvature, decrease in intraocular pressure, central serous chorioretinopathy and ocular blood flow. Advances in ophthalmic imaging devices has...
Swept-source OCT for measuring peripheral anterior synechiae

Glaucoma
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...

Paediatric Ophthalmology / Strabismus
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...Does breastfeeding protect against age-related cataract?
