Condition

Glaucoma

Glaucoma is a group of eye conditions in which the optic nerve is damaged, usually because pressure inside the eye is too high, and lost vision cannot be regained. Citicoline has the strongest evidence, rated moderate, and one small study of 60 people found better visual acuity; omega-3s are limited. That rests on one small study, and ginkgo, coenzyme Q10 and others have only limited research.
