Topical Netarsudil for the Prevention of Proliferative Vitreoretinopathy in Patients With Retinal Detachment

This is an open-label, randomized study that will test the safety and pharmacokinetics of topical netarsudil at a dose frequency of once-daily in two cohorts of patients: those with primary rhegmatogenous detachments, and those with established proliferative vitreoretinopathy. The intervention will be topical application of Netarsudil from time of diagnosis of retinal detachment to 16 weeks post-operatively. Patients will be randomized to one of the following groups: * The primary rhegmatogenous detachment cohort: A total of 24 study subjects (24 eyes) will be stratified by their lens status (12 phakic versus 12 pseudophakic). All patients will receive once per day dosing of netarsudil. * The proliferative vitreoretinopathy cohort: A total of 24 study subjects (24 eyes) will be stratified by their lens status (12 phakic versus 12 pseudophakic). All patients will receive once per day dosing of netarsudil. After surgery, patients will continue on once per day dosing of Netarsudil for a total of 16 weeks post-op.
