Novel surgical management of cyclodialysis cleft via anterior chamber perfusion: Case report

RATIONALE: Cyclodialysis cleft is a relatively rare but severe condition with persistent ocular hypotony, which can cause morphologic changes and visual loss. Here we report a case of a traumatic cyclodialysis cleft that was successfully managed with direct cyclopexy via anterior chamber perfusion. During the operation, if there is aqueous humor flowing out of the deep scleral incision, the cleft is not closed, and surgery should continue until there is no aqueous outflow. PATIENT CONCERNS: A 66-year-old man was treated for severe blunt ocular trauma of the left eye and a resultant cyclodialysis cleft, lens subluxation, choroidal detachment and a cataract. His intraocular pressure was 6 mm Hg, he presented with a shallow anterior chamber, phacodonesis, iridodonesis, 360° ciliary body detachment, and a suspicious cyclodialysis cleft in the 5 to 8 o’clock position. DIAGNOSES: ocular blunt trauma (left eye), cyclodialysis cleft (left eye), lens subluxation (left eye), choroidal detachment (left eye), cataract (both eyes). INTERVENTIONS: The cataract was extracted by phacoemulsification and a posterior chamber intraocular lens was implanted with 2 capsular tension rings, one in the lens bag and the other in the ciliary sulcus. Throughout the following month, intraocular pressure fluctuated between 4 and 6 mm Hg and the ciliary body failed to reattach. A cyclopexy via anterior chamber perfusion was thus deemed necessary and performed. OUTCOMES: After cyclopexy, intraocular pressure increased to 27 mm Hg and decreased to 16 mm Hg after brinzolamide eye drops treatment twice daily for 4 days. Subsequently intraocular pressure stabilized between 10 to 21mm Hg. Complete closure of the cyclodialysis cleft was confirmed with ultrasound biomicroscopy. LESSONS: Cyclopexy via anterior chamber perfusion for patients with cyclodialysis cleft is a simple, safe, and efficient technique that ensures a successful surgery.
