Outcome of primary rhegmatogenous retinal detachment surgery in a tertiary referral centre in Northern Ireland - A regional study.

Purpose: To report the primary and final success, functional outcome and complication rates of patients with primary rhegmatogenous retinal detachment (RRD) who underwent retinal detachment surgery in a tertiary referral centre in Northern Ireland.

Venue: Vitreoretinal service, Royal Victoria Hospital, Belfast, Northern Ireland.

Methods: This is a retrospective case series of all patients who underwent primary RRD repair between 1st of January 2013 and 31st of December 2013.

Safety of 20-gauge transconjunctival sutureless vitrectomy.

Purpose: To study the safety of 20-gauge transconjunctival sutureless vitrectomy.

Methods: Clinical data of patients who underwent 20-gauge transconjunctival sutureless vitrectomy for the first time, for various disorders, were reviewed retrospectively. The main outcome measures were the number of sclerotomies requiring suturing as well as the intra- and postoperative complications.

Retinal vessel diameter can reliably be determined in minipigs using Retinal Vessel Analyser with a microscope-mounted fundus camera.

Purpose: Retinal Vessel Analyser (RVA) is a validated instrument to measure retinal vessel diameter in humans. The purpose of this study was to assess the reproducibility (inter-observer reliability) and the repeatability (test-retest reliability) of RVA with a microscope-mounted fundus camera to determine retinal vessel diameter in minipigs.

Methods: Ocular fundus image from five anaesthetized minipigs was recorded in a digital videotape for approximately 5 min, under stable systemic arterial pressure and gas conditions.

Pars plana vitrectomy in the treatment of severe complicated toxoplasmic retinochoroiditis.

Purpose: To present the anatomic and functional results of pars plana vitrectomy performed in severe complicated toxoplasmic retinochoroiditis.

Methods: Three patients, 2 women and 1 man aged 57, 22, and 57 years, are presented. The first patient was under immunosuppressive therapy for dermatomyositis and underwent diagnostic/therapeutic vitrectomy for severe toxoplasmic panuveitis with dense vitritis.

Corneal infiltrates after corneal collagen cross-linking.

Purpose: To present a case of advancing keratoconus treated with corneal collagen cross-linking (CXL) with ultraviolet A (UVA) light and riboflavin complicated with sterile infiltrates.

Methods: The patient's cornea was de-epithelialized and CXL was performed with application of riboflavin and exposure to UVA light (370 nm, 3 mW/cm2) for 30 minutes.

Results: Early in the postoperative period, the patient presented with 11 deep stromal infiltrates of 1 to 2 mm with clear demarked edges in a circle near the limbus with some clear cornea.
