Participant Flow

No patients had abnormal PERG and could not be included in the first two arms from the baseline timepoint. This significantly altered the study since the patients could not be randomized, and the treatment of each patient was determined by the physician's discretion.

Participant milestones
Measure
Abnormal PERG Untreated
Participants recognized as Glaucoma suspects with an abnormal PERG test who have been assigned to not receive therapy or intervention.
Abnormal PERG Treated
Participants recognized as Glaucoma suspects with an abnormal PERG test who have been assigned to receive one or more drops in each eye in order to reduce the intraocular pressure by 20%. Drugs could be: Latanoprost 1 drop Once a day (QD) Bimatoprost 1 drop QD Travoprost 1 drop QD Timolol 1 drop Twice a day (BID) Dorzolamide 1 drop Three times a day (TID) Brinzolamide 1 drop BID Acetazolamide and Methazolamide depends on clinicians evaluation. If Clinicians consider necessary, he/she might combine 2 drugs in order to get the desired intraocular pressure. Latanoprost: Lower intraocular pressure (IOP) by increasing outflow of fluid from the eye. Bimatoprost: Lower intraocular pressure by increasing outflow of fluid from the eye. Travoprost: Lower intraocular pressure by increasing outflow of fluid from the eye. Timolol: Lower intraocular pressure by decreasing production of fluid Dorzolamide: Lowers intraocular pressure by decreasing intraocular fluid production Brinzolamide: Lowers intraocular pressure by decreasing intraocular fluid production Acetazolamide: Lowers intraocular pressure by decreasing intraocular fluid production Methazolamide: Lowers intraocular pressure by decreasing intraocular fluid production
