What the study is about
Persons who do not have glaucoma will have pictures taken of the optic nerve with a standard camera before and 2 weeks after starting to take a daily glaucoma eye drop to lower eye pressure. These data will be used to compare to the same procedure performed with glaucoma patients to study how glaucoma injures the eye.
Being studied: Latanoprost (0.005%)
Conditions: Glaucoma
