Microinvasive Intrascleral Double Continuous Suture Repair Surgery for Cyclodialysis Clefts.

BACKGROUND: The traditional suturing method for cyclodialysis cleft usually requires an incision in the sclera for direct suturing, resulting in greater damage and a high risk of postoperative complications. The purpose of this work was to propose a newly intrascleral double continuous suture repair technique for the treatment of cyclodialysis clefts.

METHODS: Seven patients with cyclodialysis cleft underwent microinvasive intrascleral double continuous suture repair surgery to restore the attachment of the detached ciliary body to the sclera without scleral incision. All operations were performed by the same surgeon. Preoperative and postoperative visual acuity, intraocular pressure, slit-lamp and corneal examination results, ultrasound biomicroscopy, and optical coherence tomography results were recorded.

RESULTS: Closure of the cyclodialysis cleft was achieved in seven eyes, and no obvious complications occurred after the operation. Intraocular pressure increased from preoperatively 6.8 ± 1.35 mmHg (range: 4.8-8.0 mmHg) to postoperatively 12.5 ± 4.0 mmHg (range: 8.0-20.0 mmHg) (paired-sample t -test, P < 0.01). Best-corrected Snellen visual acuity improved from preoperatively range 20/2000 to 20/63 to range 20/200 to 20/25 at the final follow-up.

CONCLUSION: In short, intrascleral double continuous suture repair surgical is safe and effective in treating cyclodialysis cleft, with minimal surgical trauma.
