Proliferative vitreoretinopathy (PVR), or secondary scarring on and around the retina, is an important cause of retinal re-detachment. The purpose of this study is to evaluate the effect of oral isotretinoin, which inhibits the growth of cells responsible for proliferative vitreoretinopathy (PVR), on recurrent retinal detachment.

Condition Intervention Phase
Proliferative Vitreoretinopathy
Drug: Isotretinoin

Study Type: Interventional
Study Design: Allocation: Non-Randomized

Primary Outcome Measures:
  • Rate of retinal attachment [ Time Frame: 6 months ]
    We will evaluate all patients for retinal attachment at 3 and 6-months following enrollment in the study.

Secondary Outcome Measures:
  • Epiretinal membrane formation [ Time Frame: 6 months ]

Estimated Enrollment: 70
Study Start Date: September 2011
Estimated Study Completion Date: August 2013
Estimated Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Primary, high-risk retinal detachment Drug: Isotretinoin
Isotretinoin 20mg daily for 12 weeks
Experimental: Recurrent RD associated with PVR
Oral isotretinoin on recurrent retinal detachment associated with Proliferative vitreoretinopathy
Drug: Isotretinoin
Isotretinoin 20mg daily for 12 weeks

Detailed Description:
Small retrospective studies have shown isotretinoin to be effective in reducing the rate of recurrent retinal detachment in patients with or at high risk for developing PVR. This is a prospective study to evaluate a low dose of oral isotretinoin in this regard. There are two arms to the study: 1) eyes with recurrent retinal detachment due to existing PVR, and 2) eyes with primary detachment and features associated with a high risk of PVR formation. Eligible and willing patients will receive a 12-week course of isotretinoin, and will be followed for retinal attachment rate, and PVR and/or ERM (epiretinal membrane) formation.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
