Tear film thickness after treatment with artificial tears in patients with moderate dry eye disease

In recent years artificial tear drops addressing tear film osmolarity have come onto the market. Increased tear evaporation and reduced tear volume results in tear hyperosmolarity. This triggers an inflammatory process leading to apoptosis of goblet and epithelial cells. Trehalose,...

Macular thickness and visual fields

The authors describe a comparison of spectral domain OCT with Humphrey visual fields (HVF) mean deviation (MD) and pattern standard deviation (PSD), examining the retinal thickness of the macula and circumpapillary retinal nerve fibre layer (RNFL) defects. Seventy-three subjects who...

Combined anti-VEGF and PDT for wet AMD

The authors report on a retrospective case series of combined anti-VEGF and photodynamic therapy (PDT) in the treatment of wet age-related macular degeneration (AMD) refractory to anti-VEGF monotherapy alone. The criteria for treatment failure of anti-VEGF monotherapy were persistent subretinal...

Disc margin delineation using spectral domain OCT

Observing progressive anatomical changes of the optic nerve head is essential in the detection of progression in glaucoma. Imaging devices continue to evolve and are useful in detecting change in established glaucoma, although probably less useful in an initial diagnosis....

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),...

Mini DMEK for acute hydrops

This is a retrospective analysis of three patients who underwent mini DMEK for massive corneal hydrops in acute keratoconus. DMEK graft was trephined or trimmed according to the size and the shape of the gap in the patient’s Descemet membrane...

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...

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...

Correlation between aqueous flare and macular microvascular status in diabetes mellitus

The authors report a cross-sectional study which was conducted to investigate the correlation between aqueous flare and macular microvascular status, assessed by optic coherence tomography angiography (OCTA) in diabetes mellitus. Fifty-two diabetic patients with non-proliferative retinopathy, 44 diabetic patients without...

Wet AMD outcomes post cataract surgery

The authors present the findings of a retrospective study looking at the progression of wet age-related macular degeneration (AMD) in patients who underwent cataract surgery. They recruited a series of 111 patients of which 38 were men and 73 were...
