Macular atrophy and choriocapillaris nonperfusion

This Japanese study compared the choriocapillaris (CC) nonperfusion area as measured on OCTA with areas of macular atrophy (MA) measured by fundus autofluoresence (FAF). A total of 44 eyes were assessed (31 were treated with anti-VEGF alone and 13 had...

Using optical coherence tomography angiography to detect MoyaMoya vasculopathy

Moyamoya (MM) disease is a chronic cerebrovascular disease that can lead to progressive stenosis of the terminal portions of the internal carotid arteries and their proximal branches. The authors carried out a cross-sectional cohort study to investigate vascular changes in...

Clinical Applications of Optical Coherence Tomography Angiography

Clinical Applications of Optical Coherence Tomography Angiography provides an informative, up-to-date review of the numerous applications of OCTA in ophthalmology. This book highlights the ways in which this relatively recent non-invasive imaging technique has been an invaluable tool for our...

Microvasculature changes of mCNV after ranibizumab treatment using OCTA

In this study the authors aim to evaluate the vascular changes of myopic choroidal neovascularisation (mCNV) after ranibizumab treatment using optical coherence tomography-angiography (OCTA). The 3×3 OCTA en face images were analysed for the absence / presence of mCNV, CNV...

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...

RCOphth (The Royal College of Ophthalmologists): Back to Basics - Byte sized topics for all

09:00 - 16:40 Join us for an immersive dive into the fascinating world of ophthalmology! Delve deep into the realm of red eyes as we uncover the hidden clues and learn to distinguish the subtle nuances that could signal danger. We'll embark on a journey through the intricate art of managing corneal ulcers, navigating the complexities of uveitis cases, and unravelling the mysteries behind disc swelling.

Oxford Handbook of Ophthalmology (Fourth Edition)

No matter what speciality you do there will always be a couple of core textbooks that everyone seems to recommend. When it comes to ophthalmology one of the most commonly cited ones is the Oxford Handbook of Ophthalmology. Having used...

Defence Medical Services Ophthalmology Conference 2024

by Dr Ben Smith, General Duties Medical Officer (Army), Tidworth, UK. This annual national meeting of tri-service defence ophthalmologists was held in the beautiful and historic setting of Merton College in Oxford, hosted by Professor Robert MacLaren, the current Professor...

Glaucoma and capillary perfusion

Elevated IOP is important but not the sole factor responsible for retinal ganglion cell (RGC) death and optic nerve damage in glaucoma. There is increasing evidence that visual loss correlates with macular inner retinal thinning. A total of 148 eyes...

OCTA to measure surgical haemodynamic changes

This study used the optical coherence tomography angiography (OCTA) technique to evaluate possible haemodynamic changes after horizontal rectus muscle surgery in 32 eyes of 16 patients; nine male, seven female. Recession / resection surgery was undertaken for two horizontal rectus...

Clinical predictors of proliferative sickle cell retinopathy

Sickle Cell Disease (SCD) is an inherited disorder resulting in production of Haemoglobin S (HbS), which aggregates in conditions of hypoxia, acidosis or hyperosmolarity. This leads to vascular stasis, thrombosis and ischaemia. The authors present a cross-sectional study (45 consecutive...
