Pars plana vitrectomy and endoresection of a retinal vasoproliferative tumor.

A healthy 31-year-old woman developed decreased vision due to vitreous hemorrhage from 2 retinal vascular lesions. Because of the patient's desire for visual rehabilitation and the concern for von Hippel-Lindau (VHL) disease-associated retinal hemangioblastomas, pars plana vitrectomy and endoresection of both lesions were performed. Surgical techniques included the use of chandelier illumination to enable bimanual manipulation of tissue, endolaser around the tumor prior to resection, endodiathermy to cauterize the tumor's feeder vessels, and long-acting gas tamponade following the retinectomy. Histopathology showed a vascular anomaly within the retina that consisted of multiple large vessels with multiple lumens and no evidence of VHL-associated retinal hemangioblastoma. Long-term follow-up revealed no evidence of recurrent disease. This surgical technique may be valuable in select patients to differentiate between retinal vasoproliferative tumors and VHL disease-associated retinal hemangioblastomas for diagnostic, therapeutic, and counseling purposes.
