Three cases of rhegmatogenous retinal detachment associated with regressed retinoblastoma after conservative tumor therapy.
OBJECTIVE
To report three cases of rhegmatogenous retinal detachment associated with regressed retinoblastoma after conservative therapy.


METHODS
Three eyes of three patients with rhegmatogenous retinal detachment, in which retinal breaks were present at the edge of the tumor scar, were treated with vitrectomy and scleral buckling.


RESULTS
In two eyes, in which cryopexy and silicone oil injection were performed, a preretinal membrane was formed that was comprised primarily of glial cells. Additional vitrectomy and membrane peeling reattached the retina. In one eye, in which photocoagulation and gas injection were performed, an initial vitrectomy and scleral buckling reattached the retina without postoperative membrane formation.


CONCLUSIONS
Vitrectomy and scleral buckling contributed to closure of the irregularly shaped retinal tear at the edge of the tumor scar. Photocoagulation and gas injection instead of cryopexy and silicone oil injection may avoid postoperative glial proliferation from the tumor scar.
