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

Figure 4

Case 10, male, 46 years old, left eye blurred for more than 5 months with micropsia and metamorphopsia for more than 2 months, a history of ankylosing spondylitis for 8 years, the left eye BCVA was 0.4. (a–c) First visit examination: (a) turbid optical media, astral vitreous degeneration, visible neovascular membrane in front of disc, and illustration OCT showing traction in the macula center. (b) FA imaging at 1 minute and 18 seconds. Inferior temporal part of the tumor leaked obviously, and the nasal retinal leaked. The peripheral retinal was observed with diffuse capillary leakage. Photocoagulation therapy was given to the tumors. BCVA after 10 months follow-up was 0.2. (c) Optomap revealed a 2PD pink tumor on the inferior temporal position, surrounded by standing laser spots. (d) FA angiography at 2 minutes and 17 seconds. The blood vessels in the ridge-like bulge region were still leaking on the nasal side, and the surrounding capillaries leaked. (e) FA imaging at 5 minutes and 36 seconds. The original nonperfusion area scattered in the laser spot; the tumor was still significantly leaking. After 5 months, the visual acuity of the left eye suddenly decreased and was 0.02. Vitreous hemorrhage was observed and the vitreous surgery was performed with tumor resection and then filled with C3F8. After 2 months of follow-up. (f) Optomap showed that the tumor on the inferior temporal area was removed, with localized laser spots. (g) FA imaging at 10 minutes and 27 seconds. The vascular leakage in the nasal ridge-like region was significantly reduced. (h) FA imaging at 28 seconds demonstrated scattered old laser spot and no fluorescence leakage in the tumor area. After 28 months of follow-up, the BCVA of the left eye was 0.8, and the lens was slightly cloudy. (i) Optomap fundus photography: inferior temporal localized old laser spots. (j) FA imaging at 11 minutes 27 seconds. Vascular leakage in the ridge-like area disappeared. (k) FA imaging at 37 seconds. No fluorescent leakage was observed in the tumor bed.
