Abstract Purpose:Retinal vasoproliferative tumors(VPT)are relatively rare, and range from being asymptomatic to those with secondary epiretinal membrane(ERM)or exudative changes that impair visual function. We report a case of VPT complicated with ERM that resolved by photocoagulation.

Case:A 29-year-old female patient, breastfeeding a 2-month-old infant, was referred to our clinic after a visit to her nearby clinic, who had initially diagnosed her with decreased left visual acuity and altered vision.

Findings:Her visual acuity was(0.7)at the time of initial examination, and the fundus revealed a mass lesion the size of one papilla on the lower-temporal side. Optical coherence tomography showed ERM. A differential diagnosis of VPT was made because of the inconspicuous and unilocular nature of the dilated tortuous inflow and outflow vessels to the mass. Although, a fluoroscopic funduscopic examination was suggested, the patient refused it as she was breastfeeding. A genetic test for von Hippel-Lindau disease revealed negative results. Therefore, VPT was finally confirmed, and photocoagulation was performed on the tumor as well as the inflow and outflow vessels, 1 week after the patient's visit. On 1 month follow-up, the ERM had resolved, and 2 months later, the tumor had regressed. Since the patient's visual acuity improved to(1.0), the treatment was terminated after 4 months.

Conclusion:Since there is no established treatment protocol for VPT, the background and disease status of the individual must be considered while planning the treatment.
