[Late recurrent retinal detachment after scleral buckling].
OBJECTIVE
To analyze the physiopathologic mechanism, therapeutic modalities, and prognosis of late recurrent retinal detachment.


METHODS
A retrospective study was conducted on late recurrent retinal detachment operated with episcleral surgery over a 15-year period. Ten patients were included in this study.


RESULTS
Late recurrent retinal detachments occurred in 0.39% of all retinal detachments repaired by episcleral surgery over 15 years. Redetachment occurred 3-7 years after surgery, with etiologies including new retinal breaks (seven cases), reopening of old breaks (three cases), and removal of scleral explant (one case). Proliferative vitreoretinopathy (PVR) grade B was seen in three cases, grade C in six cases, and grade D in one case. After reoperation, the retina was reattached in nine cases. Three eyes were treated with scleral buckle, the others underwent vitreoretinal surgery. Failure occurred in one patient who had a very high level of vitreoretinal proliferation.


CONCLUSIONS
Late recurrent retinal detachments are rare and vitreous base traction seems to be an important factor, although the associated PVR was probably a secondary factor. Treatment depends on PVR, with vitreoretinal surgery necessary in some cases. They usually have a good prognosis.
