OCTA in geographic atrophy

In this article the authors aim to give an overview of the current literature concerning the application of OCT-A in geographic atrophy (GA). GA is a disease characterised by loss of outer retinal layers including photoreceptors, degeneration of the retinal...

Optical coherence tomography – reinventing the eye examination

It has been 25 years since Huang et al. presented the first optical coherence tomography (OCT) images in Science [1]. With vast improvements in OCT technology over the years, it is now possible to acquire high-resolution cross-sectional images of the...

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...

Dacryocystosclerotherapy as an alternative to dacryocystectomy

In this article, the authors evaluate the role of sclerosing agents in dacryocystosclerotherapy (DCST) and aim to see whether it is an alternative to dacryocystectomy (DCT) in a specific group of patients. Thirteen lacrimal drainage systems of 10 patients with...

Tetracaine to reduce OCR

This study investigates the effects of Tetracaine eye drops on oculocardiac reflex (OCR) during strabismus surgery. A randomised controlled trial of 70 strabismus surgery patients aged two to 19 years was conducted with comparison of Tetracaine versus placebo. Demographics were...

5-FU in cicatricial conjunctivitis

This is a retrospective review of 56 patients with cicatricial conjunctivitis, including 25 eyes that received sub-conjunctival injections of 25-50mg of 5-fluorouracil (5-FU) as part of their treatment. Thirty-seven patients had ocular cicatricial pemphigoid (OCP) and 19 had Stevens-Johnson syndrome...

Multimodal imaging in wet AMD

This novel study set out to determine grader agreement levels of various retinal imaging techniques, commonly used in the diagnosis of wet age-related macular degeneration (AMD). Images from 52 eyes were by examined by two different observers. All images were...

Darren Hargreaves joins Sense Medical as Clinical Solutions Director

Sense Medical Ltd welcomes the new appointment of Darren Hargreaves as Clinical Solutions Director.

Density of cataract and its influence on retinal nerve fibre layer thickness

The aim of this study was to further define and model the influence of cataract on spectral domain optical coherence tomography (SDOCT) image quality and retinal nerve fibre layer (RNFL) thickness measurements. OCT quality is influenced by opacities in the...

Association between neurodegeneration and macular perfusion in the progression of diabetic retinopathy

In this prospective three-year longitudinal study, the authors aimed to explore the relation between retinal neurodegenerative changes and vessel closure (VC) in individuals with non-proliferative diabetic retinopathy (NPDR). The participants included 74 individuals with type 2 diabetes, NPDR, and Early...

Time domain vs. spectral domain in the measurement of the optic nerve head

The authors describe a prospective study of 40 participants (20 healthy and 20 with glaucoma) enrolled to compare the measurements of the optic nerve head (ONH) parameters given by time domain (TD) and spectral domain (SD) optical coherence tomography (OCT)....
