Purpose: To report a case of chronic hypotony maculopathy caused by traumatic cyclodialysis cleft and treated with 20% sulfur hexafluoride (SF6) gas tamponade with cyclocryotherapy.
Case summary: A 39-year-old woman with a history of blunt trauma developed a unilateral chronic ocular hypotony in her left eye. She was treated with topical atropine sulphate 1% for 2 months. Three years later, she was referred to our clinic for evaluation and treatment of persistent hypotony. The intraocular pressure (IOP) was 4 mm Hg and the best corrected visual acuity was 0.4. B-scan echography revealed a choroidal effusion and fundus examination showed choroidal detachment and macular folds. Gonioscopy examination revealed cyclodialysis cleft from the direction of 7 o’clock to 11 o’clock. A single bubble of SF6 20% (0.4 cc) was injected into the vitreous cavity and transconjunctival cyclocryotherapy was performed under retrobulbar anesthesia. Six months later, the IOP was 12 mm Hg and the best corrected visual acuity was 1.0. B-scan echograpy and fundus examination showed the disappearance of the choroidal effusion.
Conclusions: Gas tamponade with cyclocryotherapy may be useful in cases of cyclodialysis cleft that failed to respond to medical therapy.
