PNEUMATIC RETINOPEXY FOR THE TREATMENT OF SHALLOW RETINAL DETACHMENT CAUSED BY A RETINAL BREAK IN THE INTERCALARY MEMBRANE OF MACULA SPARING RETINOCHOROIDAL COLOBOMA

摘要

Purpose: To report the surgical outcome of pneumatic retinopexy in a patient with retinal detachment from a single break in the intercalary membrane of an eye with macula sparing retinochoroidal coloboma.Methods: Interventional case report. A 32-year-old man presented with defective vision in left eye for 6 months. Vision was 6/18 in right eye and 6/15 left eye. Examination revealed disk and macula sparing retinochoroidal coloboma in both eyes. Left eye showed a single break in the intercalary membrane with subretinal fluid (SRF) extending under the fovea. No other retinal breaks were noted. The patient was treated with pneumatic retinopexy using 0.3 ml_ of 100% C_3F_8 and postoperative prone positioning for 10 hours/day for 2 weeks. A day later, laser barrage photocoagulation with 810 nm laser was performed along the coloboma margin.Results: On first postoperative day, SRF was reduced. Optical coherence tomography showed decrease in macular cystic changes and SRF. A week later, optical coherence tomography showed further reduction of SRF and vision improved to 6/12. At 8 months, visual acuity was maintained and retina was completely attached. Findings were confirmed on optical coherence tomography, which also showed resolution of the cystoid spaces.Conclusion: Pneumatic retinopexy with laser barrage to coloboma margin can achieve and maintain retinal reattachment in eyes with macula sparing retinochoroidal coloboma with shallow SRF.
