EN BLOC RESECTION OF RETINAL VASOPROLIFERATIVE TUMOR USING 23G VITRECTOMY. A CASE REPORT.

Abstract

Purpose: Retinal vasoproliferative tumor is one of the benign vascular tumors which in advanced stages leads to exudative retinal detachment with the formation of epiretinal and subretinal membranes. In such advanced stages, one of the therapeutic options is pars plana vitrectomy. This article presents the case of a patient on whom was performed 23-gauge pars plana phacovitrectomy with en bloc resection of the tumor followed by histological confirmation.

Case report: A 70-year-old patient with a one-year history of unilateral loss of vision in his left eye was admitted to our clinic for examination in February 2018. At admission, the best corrected visual acuity in the right eye was 1.0, and in the left eye was light perception. Based on the clinical picture, sonographic examination of the eye, and fluorescein angiography, the patient was diagnosed with a retinal vasoproliferative tumor. Due to the advanced stage of disease, we proceeded with surgical intervention. We performed 23-gauge phacovitrectomy with a bloc resection of the tumor. Subsequent histological examination confirmed the presence of the presumed tumor. The follow-up exam a few months later showed a completely attached retina with silicone oil tamponade, without exudative retinopathy. However, the best corrected visual acuity improved only slightly to the ability to count fingers at one meter.

Conclusion: Pars plana vitrectomy with en bloc resection of retinal vasoproliferative tumor is one of the therapeutic modalities in advanced stages.
