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.
