Efficacy of Topically Administered Rho-Kinase Inhibitor AR-12286 in Patients With Exfoliation Syndrome and Ocular Hypertension or Glaucoma

Journal of Glaucoma - Fri, 08/26/2016 - 12:43am
Purpose: To evaluate the efficacy of rho-associated protein kinase inhibitor, AR-12286 topical solution, for its effect in eyes with exfoliation syndrome (XFS) and ocular hypertension (OHT) or exfoliative glaucoma (XFG) and examine any lasting effect on intraocular pressure (IOP) after discontinuation.
