Comparative Study on the Efficacy and Safety of Tumor Resection in Vitrectomy for Retinal Vasoproliferative Tumors

Figure 3

Case 8, female, 60 years old, left eye blurred for more than 3 years and 1 month, BCVA was 0.6. (a–c) Before surgery: (a) optomap showed an approximately 4 PD pink tumor-like mass around the peripheral retina at 5 o’clock, surrounded by a large number of yellow-white hard exudation and local tractional retinal detachment on the superior temporal area; illustrated OCT showed a macular hole. (b) FA imaging at 12 minutes and 19 seconds. The para-optic disc area showed hyperfluorescence with nasal vessels distorted. (c) FA imaging at 1 minute and 17 seconds showed that the blood vessels in the tumor bulged and expanded in clusters; the fluorescence filling degree was staggered, the surrounding fluorescence was blocked, or the fluorescence was seen through the sheet. Combined anterior and posterior segments surgery was conducted with cryotherapy, stripping the inner limiting membrane, filling with C3F8 gas, and injection of triamcinolone acetonide. She was followed up for 17 months, and the BCVA was 0.8. (d) Optomap displayed atrophic scars in the tumor and the inset demonstrated macular hole closure. (e) FA imaging at 14 minutes 48 seconds (leakage area around the optic disc disappeared). (f) FA imaging at 13 minutes 54 seconds. The tumor atrophied and disappeared, surrounded with scattered laser spots without fluorescence leakage.
