Optical coherence tomography in patients exposed to vigabatrin

Vigabatrin is used to treat epilepsy and can lead to increased levels of gamma-aminobutyric acid (GABA) in the brain and in the retina leading to binasal visual field defects. Although not the first line of treatment for adults it is...

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...

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 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),...

Metamorphopsia in idiopathic epiretinal membranes

The Amsler grid is commonly used for self-monitoring, but is qualitative and has low sensitivity. The M-chart reduces the amount of spatial redundancy (‘filling in’) in the Amsler grid. The Orientation Discrimination (OD) test studied in this paper consists of...

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...

A paediatric case of central retinal artery occlusion following antibiotics and decompression surgery for orbital cellulitis

Orbital cellulitis is an ophthalmic emergency that warrants urgent management in the hospital setting [1]. This occurs more frequently in the paediatric population where it is often secondary to sinus infections. Delay in treatment could result in severe complications including...
