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...

Changes in retinal and choroidal microcirculation after strabismus surgery

The aim was to evaluate retinal and choroidal microcirculation using optical coherence tomography angiography after strabismus surgery. This was a cross-sectional observation study of 44 eyes of 44 patients. Patients were split into three groups: (1) one-muscle horizontal surgery (n=9);...

Do bilateral same day intravitreal injections increase the risk of endophthalmitis?

This large retrospective cohort study reviewed all patients who had bilateral intravitreal anti-vascular endothelial growth factor (VEGF) injections between April 2012 and August 2017. There were 101,932 procedures performed in 5890 patients. The two most common indications for injections were...

OCT angiography metrics in children

This prospective study aimed to quantify the vessel density of both the macular and optic nerve and foveal avascular zone (FAZ) values in 92 normal eyes of 92 children (42 boys, 50 girls) aged 13.4 ±2.65 years (seven to 18)....

Macular atrophy with aflibercept

The authors of this paper set out to investigate the prevalence of macular atrophy in treatment-naive patients with neovascular AMD undergoing aflibercept monotherapy (three monthly loading injections followed by subsequent treatment every two months). Case notes over a three year...

Screening for Sickle Cell Retinopathy (SCR): Why we do wide-field imaging, OCT/OCT-A for SCR – Newcastle upon Tyne Hospitals NHS Foundation Trust

I have been working in ophthalmology for over five years as a photographer and research co-ordinator, and it is fascinating, rewarding, and interesting to learn all about the different diseases associated with the eye. One condition that has been a...

Reduced blood flow and age-related macular degeneration

This was a prospective cross-sectional study assessing changes in blood flow velocity in patients with age-related macular degeneration (AMD) using a retinal function imager. Sixty eyes with wet AMD were compared to 53 control eyes and the average blood flow...

The clinical spectrum of albinism

The authors sought to examine clinical correlates that may be related to foveal development in albinism with an aim to qualitatively describe the phenotype spectrum of albinism. Binocular best corrected visual acuity ranged from 20/20 to 20/80. Best corrected visual...

Macular choroidal changes after inferior oblique muscle surgery

This study was undertaken to investigate the retinal neurovasculature, choroidal thickness and choroidal vascular index (CVI) changes at the macula at one week, one- and three-month intervals post inferior oblique muscle myectomy. The hypothesis was that, given the close proximity...

Retrograde maculopathy in glaucoma

Macular optical coherence tomography (OCT) analysis can be used for quantitative measures of optic nerve atrophy at a location far away from the optic nerve head. This has recently led to the discovery of microcystic macular oedema (MME), in the...

Type 3 macular neovascularisation (MNV) due to age-related macular degeneration

This paper systematically reviews and summarises the current knowledge on type 3 neovascularisation due to age-related macular degeneration which is defined as neovascularisation originating from the retinal deep capillary plexus that grows towards the outer retina often penetrating the level...

OCTA FAZ measurements in vein occlusion

Previous studies have confirmed that foveal avascular zone (FAZ) enlargement is correlated with visual acuity impairment in patients with retinal vein occlusion (RVO). This current study aimed to evaluate the OCT angiography parameters: the area of FAZ, foveal and parafoveal...
