Corneal Graft Rejection: Is it Reflected in Peripheral Immune Cells? Results of a Prospective Multicenter Study (VISICORT).

Background: Allogeneic graft rejection is the leading cause of graft failure in corneal transplantation (CT) despite the immune privilege of the anterior chamber and corneal bed. The ability to identify patients at higher risk of acute rejection before or after CT could have a major impact on the clinical management of these patients.

Methods: To address this important issue, a multicenter European cohort of low-risk (n = 142) and high-risk (n = 102) CT recipients was established, and the immune system was evaluated in detail in peripheral blood mononuclear cells and plasma before and 6 and 12 mo posttransplantation.

Pseudophakic cystoid macular oedema and posterior capsular opacification rates after combined phaco-trabeculectomy vs. phaco alone.

Purpose: To assess the risk for pseudophakic cystoid macular oedema (PCME) and posterior capsular opacification (PCO) associated with combined cataract surgery and trabeculectomy compared to cataract surgery alone.

Methods: Data analysis of subjects who underwent routine cataract surgery without and with concomitant trabeculectomy at the Department of Ophthalmology, Bristol Eye Hospital, the UK, between January 2008 and December 2017. Odds ratios (ORs) for PCME between the types of surgeries were calculated using univariate and multivariate regression analysis.

Complications of pupil expansion devices: a large real-world study.

Purpose: To assess the risk for uveitis, pseudophakic cystoid macular edema (PCME), and posterior capsular opacification (PCO) associated with the use of pupil expansion devices in cataract surgery.

Design: A retrospective comparative cohort study.

Participants: Patients who underwent routine cataract surgery with and without pupil expansion devices at the Department of Ophthalmology, Bristol Eye Hospital, UK, between January 2008 and December 2017.

Outcomes after reversed corneal graft rejection: a report from the European VISICORT project.

Objective: This study aims to describe the outcome of corneal grafts, both low risk and high risk, after successfully reversed immunological rejection.

Methods: Datasets on reversed rejection episodes in penetrating and endothelial keratoplasties between 2014 and 2019 (n=876) were extracted from the Adverse Immune Signatures and their Prevention in Corneal Transplantation database, which contains the prospectively and consecutively collected corneal transplants from five European centres. Stratified by the preoperatively determined risk status for immunological rejection, the outcome parameters analysed included visual acuity, intraocular pressure, endothelial cell density and central corneal thickness before and after reversed rejection episodes.

Type 1 and type 2 diabetes predisposed to higher Nd:YAG capsulotomy rates following cataract surgery: analysis of 53,471 consecutive cases.

Objective: To assess the effect of diabetes type on Nd:YAG capsulotomy rates following cataract surgery.

Design: A retrospective cohort study.

Methods: All patients who underwent cataract extraction at the Department of Ophthalmology, Bristol Eye Hospital, Bristol, UK, between 2003 and 2017 were included.
