Severe hypotony after macular translocation surgery with 360-degree retinotomy

PURPOSE: To report a case of severe hypotony after macular translocation with 360-degree retinotomy. DESIGN: Interventional case report. METHODS: A 50-year-old woman with myopic neovascular maculopathy underwent macular translocation with 360-degree retinotomy in her left eye. RESULTS: After the second procedure of silicone oil removal, severe hypotony developed. No clear sign of leakage was found. Pure perfluoropropane gas tamponade was then performed, which resulted in temporal resolution of severe hypotony, but the hypotony recurred as the gas bubble was absorbed. Ten weeks after the second surgery, the hypotonous eye was refilled with silicone oil. No apparent cyclitic membrane was observed intraoperatively. After this procedure, the choroidal and retinal folds regressed; intraocular pressure has been between 5 and 7 mm Hg for more than 4 months thereafter. CONCLUSION: Severe hypotony can occur as a complication of otherwise uneventful macular translocation with 360-degree retinotomy.
