A 22‑year‑old female developed painless vision loss right eye (OD). Visual acuity was counting fingers OD, 20/20 OS. The OS was entirely normal. Examination of OD disclosed an orange‑colored retinal mass located inferotemporally, measuring 7 mm in basal diameter and 4 mm in thickness [Figure 1]. There was a shallow nonrhegmatogenous total retinal detachment, intraretinal/subretinal exudation, preretinal hemorrhage and macular edema. The features were consistent with a retinal vasoproliferative tumor (VPT) and treatment with Iodine I‑125 plaque radiotherapy with a dose of 4000 cGy was provided. Eleven months later, visual acuity had improved to 20/30 OD with tumor involution and resolution of subretinal fluid and macular edema. Four years later, visual acuity was 20/20 with stable findings and complete regression of the VPT to a 2.0‑mm thick fibrous nonvascular mass [Figure 2]. There was no evidence of radiation maculopathy or papillopathy.
