Treatment of Hypotony Maculopathy Caused by Traumatic Cyclodialysis with Vitrectomy, Gas Tamponade, and Cryotherapy

Purpose: To report a case of hypotony maculopathy caused by traumatic cyclodialysis and treated by vitrectomy combined with gas tamponade and cryotherapy. Methods: A 35-year-old man with hypotony maculopathy caused by traumatic cyclodialysis was unsuccessfully treated with conservative medical therapy, laser photocoagulation, and direct cyclopexy. The intraocular pressure (IOP) was 2 mm Hg and the vision was counting finger with chorioretinal folds. Vitrectomy combined with gas tamponade and cryotherapy was performed without lens surgery 5 months after trauma. Results: After vitrectomy, fundus photograph and optical coherence tomography revealed complete loss of preoperative chorioretinal folds. The visual acuity improved to 0.3 and IOP was maintained within a normal range during the 24 month follow-up. Conclusions: This case shows that vitrectomy combined with gas tamponade and cryotherapy is effective for the treatment of traumatic cyclodialysis with persistent hypotony, probably without lens surgery.
