claimMethods: This critical narrative review examines interventional trials for nine prominent DBs relevant to AD: docosahexaenoic acid (DHA), curcumin, resveratrol, epigallocatechin gallate (EGCG), nicotinamide riboside (NR), tricaprilin, vitamin E (α-tocopherol), cannabinoids, and NIC5-15 (D-pinitol).

claimImportantly, while elevated intraocular pressure (IOP) is a well-established risk factor and the only available treatment target, it is neither necessary nor sufficient for the development of glaucoma, as evidenced by the existence of normal-tension glaucoma and the observation that many patients continue to progress despite achieving target IOP levels.

claimIt is estimated that the number of individuals affected by glaucoma will continue to rise, with substantial socioeconomic impact due to vision loss and associated disability.Age is the most prominent risk factor, but genetic predisposition, vascular dysregulation, and systemic metabolic dysfunction have also been implicated in disease susceptibility and progression.

claimStudies suggest that up to 28% of retinal ganglion cells may be lost before early visual field defects become apparent.Advances in imaging, home-based visual field monitoring, and artificial intelligence-assisted analysis are being developed to improve early detection and risk stratification, but challenges remain in predicting individual disease trajectories.
