Is serum ACE useful in diagnosing sarcoidosis in uveitis patients?

This retrospective clinical notes review assesses whether serum angiotensin converting enzyme (ACE) is useful in the diagnosis of sarcoidosis in patients presenting with uveitis. There were 1035 consecutive subjects presenting with uveitis as part of baseline investigations had a serum...

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...

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...

Type 3 CNV and anti-VEGF

The purpose of the study was to determine the differences between aflibercept and ranibizumab in terms of their therapeutic efficacy in the treatment of Type 3 neovascularisation. The authors highlight that the dominant mechanism for Type 3 neovascularisation development is...

Cataract surgery in patients with Vogt-Koyanagi-Harada

This retrospective, interventional case series of 286 patients (408 eyes) assessed visual outcome and prognostic factors in patients with Vogt-Koyanagi-Harada (VKH) undergoing cataract surgery between September 2008 and December 2017. Two groups were reviewed. The first group (352 eyes) had...

Radiation maculopathy

This is a retrospective non-randomised study of 13 consecutive eyes of 13 patients affected by radiation maculopathy secondary to eye irradiation for primary uveal melanoma (Iodine-125 brachytherapy). All patients were treated with a single intravitreal 0.7mg dexamethasone implant and full...

Macular pigment and dark adaptation in older population with normal maculas

Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...

Ranibizumab safety in pregnancy

Vascular endothelial growth factor (VEGF) plays a pivotal role during pregnancy, and systemic anti-VEGF administration during this period should thus be avoided. VEGF is expressed in multiple embryonic and foetal tissues during development, with the highest levels found in 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),...

2018 update on intravitreal injections

In this review article the authors have highlighted the standardised and structured approach to intravitreal injections (IVI) by examining the recent evidence-based literature. IVI is the most commonly performed procedure worldwide with low potential risk of endophthalmitis. IOP spikes are...
