Results from the Primary Tube Versus Trabeculectomy Study and translation to clinical practice.

Purpose Of Review: The Primary Tube Versus Trabeculectomy (PTVT) Study is a multicenter randomized clinical trial comparing the safety and efficacy of tube shunt surgery and trabeculectomy with mitomycin C (MMC) in eyes without previous incisional ocular surgery. This article reviews results from the PTVT Study and suggests how they may be translated to clinical practice.

Recent Findings: Tube shunt surgery had a higher failure rate than trabeculectomy with MMC in the PTVT Study, and the difference was statistically significant at 1 year but not at 3 years and 5 years.

Prophylaxis with intraocular pressure lowering medication and glaucomatous progression in patients receiving intravitreal anti-VEGF therapy.

Aim: To investigate whether pretreatment with pressure-lowering medication prior to anti-vascular endothelial factor (VEGF) injections had an effect on glaucomatous progression in patients with preexisting glaucoma or ocular hypertension (OHT).

Methods: A total of 66 eyes from 54 patients with a preexisting diagnosis of glaucoma or OHT, treated with six or more anti-VEGF injections were selected for chart review. Primary outcome measures were rate of visual field loss in dB/year, rate of change in retinal nerve fiber layer (RNFL) thickness in microns/year, and need for additional glaucoma intervention.

Effects of Intravitreal Anti-VEGF Therapy on Glaucoma-like Progression in Susceptible Eyes.

Unlabelled: PRéCIS:: Intravitreal anti-vascular endothelial growth factor (VEGF) injections may accelerate glaucomatous change in patients with preexisting glaucoma or ocular hypertension (OHT). The safety of long-term injections in this specific population may be reflected in the need for additional glaucoma interventions.

Purpose: The purpose of this study was to investigate whether repeated anti-VEGF injections accelerate structural and functional glaucomatous change in eyes with preexisting glaucoma or OHT.
