Optic Nerve Head Strain in Non-glaucoma Subjects
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.
• Adults who have no history of OAG
• Have an ocular examination by a glaucoma specialist with no indications of OAG
• Have normal optical coherence tomography findings in the retinal nerve fiber layer.
• Over age 30 will be included from
• Both sexes
• All ethnic groups.
• Optic neuropathy.
• Both suspects and those with glaucoma damage will be included.
• When both eyes meet inclusion and exclusion criteria, both eyes will be included in the study and statistical methods will be used to account for correlations between eyes within the same individual.
