Nighttime Sleep Symptoms and Sleep-Relevant Medication Documentation Among Adults Receiving Buprenorphine for Opioid Use Disorder.

Ahmed glaucoma valve is a pressure-sensitive, unidirectional valve mechanism crucial for controlling elevated intraocular pressure (IOP) in refractory glaucoma cases where medical management, laser procedures, or conventional filtering surgery has failed or is likely to fail. AGV may also be utilized as a primary surgical intervention in select cases. However, corneal decompensation represents a significant complication associated with these devices, with reported incidence ranging from 3.3% to 27% across various studies [-]. Multiple mechanisms have been proposed for AGV-related endothelial damage and subsequent corneal decompensation, including direct or intermittent tube-endothelial contact, chronic IOP elevation, and prolonged exposure to antiglaucoma medications. Previous studies have shown that tubes closer to the cornea are associated with greater endothelial cell loss [,]. ASOCT has emerged as a valuable tool for anterior segment evaluation. In cases of AGV-related corneal decompensation, it enables precise measurement of critical parameters, including the tube-endothelial distance, the tube-iris distance, corneal thickness, and stromal scarring. These measurements provide crucial information for surgical planning, particularly when considering DSAEK. We present our experience with ASOCT-guided management of 11 eyes with AGV-related corneal decompensation and propose a systematic decision-making protocol for AGV retention versus explantation.
