Two patients with known histories of benign retinal tumors presented with rhegmatogenous retinal detachments (RRD) in the same eye. One had a retinocytoma and presenting vision of 20/50, while the other had congenital hypertrophy of the retinal pigment epithelium and vision of 20/30. Both had subretinal fluid accumulation in a configuration consistent with a retinal break near the tumor; however, no breaks were detected on examination or intraoperatively. Pars plana vitrectomy (PPV), drainage retinotomy, fluid-air exchange, barrier laser around the tumor, and gas tamponade successfully reattached the retina in both cases. After 12 and 6 months of follow-up, respectively, final vision was 20/25 and the retina remained attached. RRD may be associated with benign retinal tumors presumably with microscopic breaks at the margins. In these cases, PPV, drainage retinotomy, fluid-air exchange, endolaser around the tumor, and gas tamponade can be effective for treatment.
