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...
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...
Does lower eyelid entropion repair alter corneal topography?
The authors aimed to analyse the corneal morphology before and after advancement of posterior lower eyelid retractors (LERs) alone or in combination with a lateral tarsal strip (LTS) for lower eyelid involutional entropion. Retrospective analysis of 24 consecutive elderly patients...
Treatment and outcomes for Peters anomaly (PA)
The purpose of this study was to evaluate the experience of patients with Peters anomaly (PA) and their treatment results. The study reviewed records of 27 patients (32 eyes); 74% male. Treatment included medical follow-up, optical iridectomy and penetrating keratoplasty...
Progression of macular atrophy on long-term anti-VEGF therapy for AMD
This retrospective study evaluated the progression of macular atrophy in 53 eyes of 53 patients receiving AntiVEGF Therapy for age-related macular degeneration (nAMD), for at least six years. None of the patients had any macular atrophy (MA) at presentation. MA...
Microsporidia-induced stromal keratitis: a new cause of presumed immune stromal (interstitial) keratitis
This is a non-comparative retrospective observational case series from India from 1 October 2020 to 31 January 2021. The inclusion criteria were: (1) presence of nummular / coin shaped lesions with at least one >2mm in size and / presence...
Comparison of structural and functional features in primary angle closure and open-angle glaucoma
In this large cross-sectional study, differences in structural and functional damage were assessed among patients with primary open-angle glaucoma (POAG) and primary angle closure glaucoma (PACG) with optical coherence tomography and reliable visual field testing. Two-hundred and eighty-three patients with...
Tumour characteristics influencing visual field outcomes
This retrospective study aimed to explore correlations between pituitary tumour characteristics which influenced visual field changes. Cases of transsphenoidal surgery from a six-year period resulting in a pathologic diagnosis of pituitary adenoma from a single centre were identified. Individuals were...
Management of traumatic corneal perforations with anterior lamellar techniques: The mini-DSAEK
The authors present the first case report in which a mini (reduced diameter) Descemet’s stripping automated endothelial keratoplasty (mini-DSAEK) has been used to manage a traumatic corneal perforation. A 69-year-old male presented with 6/36 best spectacle-corrected visual acuity (BSCVA) and...
