Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Early glaucoma

The study group consisted of consecutive unilateral glaucoma patients, categorized as early stage by Hodapp-Anderson-Parrish classification.

No interventions assigned to this group

Normal subjects

Normal control subjects had a normal ocular examination, Intraocular pressure (IOP) \<22 mmHg, no past history of high IOP, no family history of glaucoma, normal optic disc morphology and visual field in both eyes. One eye of control subject was randomly selected.

No interventions assigned to this group
