Ocular surface in donor eyes after CLAU

This retrospective study examined ocular surface stability of donor eyes following conjunctival limbal autografts (CLAU). Forty-five eyes underwent CLAU with chemical burns being the most common indication. All but two eyes had just over 4 o’clock hours of CLAU segment...

Finasteride and central serous chorioretinopathy

The pathophysiology of central serous chorioretinopathy (CSC) is complex and has not been fully elucidated. Suggested theories include hyperpermeability and increased hydrostatic pressure in the choroidal vasculature, which creates RPE detachments overwhelming the RPE barrier function, leading to accumulation of...

Quarter DMEK

This case report describes a novel technique where one quarter of Descemet’s membrane (DM) was transplanted during a quarter-descemet membrane endothelial keratoplasty (DMEK) procedure. DMEK graft was prepared from a 58-year-old corneo-scleral donor after one week in culture. Peripheral DM...

Rituximab efficacy for juvenile idiopathic arthritis

This is a retrospective study about the long-term efficacy of rituximab in patients with severe juvenile idiopathic arthritis (JIA)-associated uveitis. A total of eight patients (15 eyes) were recruited in this study in a single tertiary referral centre from Italy....

Topography based keratoconus progression after corneal collagen cross-linking

Case 1 describes a 35-year-old man with progressive keratoconus (PK). His best corrected visual acuity (BCVA) was right 20/80 (-5.25/-7.75 x 85) and left 20/20 (+4.75/-5.00 x 90). His Ks were right 36.32/48.02 D and 41.15/46.41 D. Right central cornea...

Low cost drainage device use in paediatric glaucoma

This is a prospective study from a tertiary referral centre from India of 34 eyes (31 patients) under 16 years with uncontrolled refractory glaucoma with medical treatment. A low cost glaucoma drainage device (GDD) – Aurolab aqueous drainage implant (ADDI),...

Moxifloxacin 0.5% for bacterial keratitis

The authors report on the results of a randomised controlled trial comparing commercially available non-preserved moxifloxacin 0.5% vs. a combination of fortified cefazolin 5% and tobramycin 1.3% in the treatment of moderate bacterial keratitis without perforation. Corneal scrapings were collected...

Sutureless, scleral fixated-IOLs

This was a retrospective cohort study of 112 sutureless, scleral-fixated posterior chamber intraocular lens implantations (SSFCIOL) over a four-year time period. Mean follow-up duration was 13.0 ±10.4 months. The primary indication for SSFCIOL was dislocation of IOL due to zonular...

Corneal crosslinking in pellucid marginal degeneration

Fourteen studies were included in this first review examining the use of corneal-crosslinking (CXL) to treat pellucid marginal degeneration (PMD). PMD is a bilateral, non-inflammatory corneal thinning disorder characterised by inferior peripheral corneal thinning 1-3mm from the limbus in the...

Use of botulinum toxin A in the treatment of intermittent exotropia

In this prospective cohort study, the authors aimed to evaluate the efficiency of botulinum toxin A (BTA) injection in the treatment of intermittent exotropia (IXT) and examine factors affecting treatment outcomes. Seventy-four patients diagnosed with any type of IXT were...

Dichoptic vs occlusion therapy outcomes for anisometropic amblyopia

The authors evaluated a binocular Tetris game for Android phones and compared its effectiveness, compliance and adverse events with part-time patching in children with anisometropic amblyopia. This was a prospective randomised study. Group 1 played the game for two hours...

Age-related distance esotropia – what are the clinical characteristics?

The authors present a retrospective case review of individuals with primary divergence insufficiency or age-related distance esotropia, over a 15-year period. Inclusion criteria allow for the difference between near and distance angles to be patient reported or objectively measured. One...
