Peripapillary choriocapillaris blood flow in glaucoma. Part 2. Peripapillary choriocapillaris dropout and its relationship to the progression of glaucomatous optic neuropathy

Choriocapillaris dropout within the beta zone of peripapillary choroidal atrophy is a significant marker in glaucoma diagnosis. This marker is associated with retinal nerve fiber layer thinning, retinal ganglion cell loss, and visual field deterioration. This review highlights data showing a correlation between choriocapillaris blood flow and the progression of glaucomatous optic neuropathy, suggesting that choriocapillaris dropout serves as a vital biomarker for glaucoma progression, and provides literature evidence on how choriocapillaris blood flow changes relate to glaucoma treatment.
