Inner nuclear layer of the retina showing increase in thickness in diabetic macular oedema

Diabetic retinopathy is one of the leading causes of blindness in the developed world. With optical coherence tomography (OCT), it has become possible to image the retina in vivo and to measure retinal oedema by measuring retinal thickness (RT) with...

Comparison of SIA from femtosecond laser and manual CCIs for cataract surgery

This study group compared the differences in surgically induced astigmatism (SIA) vector, flattening effect, torque and wound architecture following both femtosecond laser and manual clear corneal incisions (CCIs). A double-armed, randomised, prospective case series was conducted. Cataract surgery was performed...

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...

Near-infrared autofluorescence to diagnose retinal laser injuries

This retrospective observational case series aimed to assess whether near infrared autofluorescence (NIR-AR) imaging is a useful imaging modality in the diagnosis of hand-held laser retinal injuries. Twelve patients from two centres underwent ophthalmic assessment and retinal imaging including fundus...

Progression of retinitis pigmentosa

This retrospective study evaluates the rate of progression of retinitis pigmentosa (RP) using multimodal imaging, including spectral-domain optical coherence tomography (SD-OCT), fundus autofluorescence (FAF) and microperimtery (MP). Traditional tests used to evaluate RP, for example, Goldmann visual fields and ERG...

Hypothyroidsim and acute central serous chorioretinopathy – is there a link?

This cross-sectional study included 71 consecutive acute central serous chorioretinopathy (CSC) patients and 70 age-matched healthy control subjects. Systemic findings, including serum levels of thyroid hormones, thyroid stimulating hormone (TSH), mean arterial pressure (MAP), pulse rate, serum lipid levels and...

Retinal ischaemia on OCTA and diabetic retinopathy grade

The authors quite rightly point out that quantification of retinal ischaemia has the potential to serve as a biomarker for diabetic retinopathy disease progression. They set out to investigate the relationship between area of ischaemia on a swept source OCTA...

Anatomical and functional outcomes following switching from aflibercept to ranibizumab in NARMD

This is a six-month, prospective, single-arm study in the UK and Germany. A total of 100 patients were enrolled (one in the primary failure group, 99 in the suboptimal treatment response group), treated three-monthly intravitreal ranibizumab injections (0.5mg), and then...

Intravitreal Ziv-Aflibercept: safety analysis

Ziv-Aflibercept (Zaltrap; Sanofi-Aventis U.S LLS, Bridgewater, NJ) was originally introduced as an intravenous formulation for metastatic colorectal cancer. The adoption of Ziv-Aflibercept in ophthalmic practice was similar to bevacizumab, and reports have previously examined one to two year visual outcomes...

Characteristics of limbal lymphatic vasculature on confocal microscopy

This ex vivo study aims to describe the morphological characteristics of the human limbal lymphatic vasculature using confocal microscopy and immunofluorescence. Twelve corneal specimens are obtained from human donor eyes. These corneal buttons are not suitable for transplantation due to...

OCT choroidal signs for congenital retinal pigment epithelium hypertrophy

Congenital hypertrophy of the retinal pigment epithelium (CHRPE) on ocular coherence tomography (OCT) has the characteristic sign of RPE thickening and hyper reflectivity. However, the underlying choroid characteristics remain under researched. This retrospective study utilised data from an ophthalmic oncology...

Medial rectus anatomy in exotropia

This study investigates the differences between extraocular muscles in patients with intermittent exotropia and normal controls regarding muscle fibre arrangement and diameter, and distribution and activation of satellite cells. Fifteen patients were recruited having medial rectus resection surgery. Resection sections...
