Intrascleral sewing-machine technique: A Grooveless/flapless cyclopexy technique for large traumatic Cyclodialysis cleft repairs in pars plana vitrectomy.

Purpose: To describe a minimally invasive technique for the repair of large traumatic cyclodialysis clefts using intrascleral sewing machine suture and overhand friction knot techniques in pars plana vitrectomy.

Methods: This prospective, noncomparative, interventional case series included seven eyes of seven patients with a large traumatic cyclodialysis cleft. The sewing machine technique was modified by an intrascleral approach. The procedure was transconjunctival or subconjunctival performed without scleral flaps/grooves. An overhand friction knot was used to lead the cutting ends of the suture buried in the scleral tunnel.

Results: The closure of the cyclodialysis cleft was achieved in seven eyes. The mean follow-up duration was 49.1 ± 15.6 weeks (range, 30-70 weeks). The intraocular pressure increased from 7.3 ± 2.1 mm Hg (range, 5-11 mmHg) preoperatively to 13.6 ± 2.4 mm Hg (range, 10-17 mmHg) postoperatively ( P < 0.01). The best-corrected visual acuity improved from a mean of 2.76 ± 2.77 logarithm of the minimum angle of resolution preoperatively to 0.63 ± 0.82 logarithm of the minimum angle of resolution at the final follow-up ( P < 0.01).

Conclusion: In conclusion, the present technique is safe and effective in the treatment of large traumatic cyclodialysis clefts with minimal surgical trauma and a decreased surgical duration.
