Planned delayed relaxing retinotomy for proliferative vitreoretinopathy.
OBJECTIVE
A program involving three operations-the first to reattach most of the retina under silicone oil, the second to reattach the remaining retina by planned delayed relaxing retinectomy (PDRR), and the third to remove silicone oil-was tested.


METHODS
Review of electronic records of patients receiving PDRR for proliferative vitreoretinopathy (PVR). The primary end point was reattached retina without silicone oil.


RESULTS
Eighty-seven patients had PVR and 27 received PDRR (mean age: 66.6 years; mean follow-up: 2.3 years). Ten patients had grade B PVR, 8 had CP1 to CP6, and 7 had CA2 to CA6. Twenty-four (89%) patients achieved a reattached retina without silicone oil. Mean logarithm of the minimum angle of resolution visual acuities were 1.41 (standard deviation = 0.67) at presentation and 1.21 (standard deviation = 0.58) at final follow-up. Four patients had glaucoma and 1 had scleromalacia. The overall success rate for all patients with PVR was 85% reattached retina without oil tamponade.


CONCLUSIONS
PDRR contributes to a high chance of reattached retina and oil removal in PVR.
