Purpose: To evaluate the clinical effects of direct cyclopexy in the treatment of traumatic cyclodialysis cleft.
Methods: This is a retrospective case study. Patients with traumatic cyclodialysis cleft, who were treated with direct cyclopexy and had complete medical records at Tianjin Eye Hospital between February 2021 and August 2022 were selected. The detailed characteristics of the 23 patients were analyzed. Preoperative and postoperative visual acuity, intraocular pressure (IOP), and the extent of ciliary detachment were recorded. All patients were followed up for six months.
Results: 19 of the 23 patients who underwent single direct cyclopexy, the other 4 patients with severe posterior segment damage underwent direct cyclopexy combined with vitrectomy, suprachoroidal drainage, etc. After surgery, 22 of the 23 patients successfully reset the ciliary body, including four patients who underwent combined operations, which showed a statistically significant difference (P < 0.01). The mean preoperative IOP was 6.48 ± 1.62 mmHg and it has a different degree of rebound in 21 cases reaching 13.29 ± 2.11 mmHg on 6 months after operation, including 6 cases of transient high intraocular pressure (> 21 mmHg) (P < 0.01). Best corrected visual acuity was increased from preoperatively 0.60 ± 0.21 logMAR to 0.38 ± 0.26 log MAR postoperatively, in which the vision > 0.3 logMAR reached 65.2% (P < 0.01).
Conclusion: Direct cyclopexy with or without vitrectomy is an effective method for treating traumatic ciliary body detachment.
