 Cornea considerations in glaucoma surgery
Preeya Gupta, MD, Durham, North Carolina, shared some information on important cornea considerations in glaucoma, highlighting both ocular surface disease and the corneal endothelium.
Glaucoma management causes dry eye and ocular surface disease (OSD), she said. Both medications and surgery can disrupt the surface.
OSD has a real impact in glaucoma management, she said, and has significant impact on vision quality and visual function. It can also negatively impact drop compliance.
Dr. Gupta highlighted several modern therapies that may reduce OSD, including preservative-free glaucoma medications, SLT, and MIGS as a standalone procedure or combined with cataract surgery. Future options could include a drug delivery implant.
The corneal endothelium is another consideration, Dr. Gupta said. The purpose of the endothelium is to keep the cornea clear, she said, but it does not regenerate, and many things can damage it (including glaucoma surgery). For endothelium surveillance, Dr. Gupta mentioned pachymetry, slit lamp examination, and specular microscopy all as viable options. Monitoring endothelial cell count is important, particularly in those post-glaucoma surgery who may be at risk for endothelial cell loss, but there is currently no firm consensus on the use of endothelial cell count monitoring, Dr. Gupta said. With new technologies, ophthalmologists will want to determine how to best follow these patients, she said
