Gas tamponade and cyclocryotherapy of a chronic cyclodialysis cleft

摘要: Aims: To describe a minimally invasive technique to treat chronic large cyclodialysis cleft that had failed respond medical therapy. Methods: A 51-year-old man with history of blunt trauma developed unilateral ocular hypotony. He was treated topical atropine 1% for 3 months. 12 months later, the patient referred our glaucoma service evaluation and treatment persistent Ultrasound biomicroscopy (UBM) displayed extending from 6 o’clock positions. B-scan echography revealed peripheral choroidal effusion. single bubble 20% sulfur hexafluoride injected into vitreous cavity transconjunctival cyclocryotherapy performed. Results: After gas absorption, intraocular pressure increased mm Hg became steady during follow-up. showed disappearance effusion, UBM complete closure 8:30 positions 9:30 small remained after treatment, but distance between scleral spur ciliary boby decreased, limited at back due scar formation. Conclusion: Gas tamponade represents is worth considering patients clefts associated shallow anterior chamber This should be useful in cases are not amenable more conservative efforts.
