Abstract
PURPOSE
Performing simultaneous vitrectomy and cataract procedure has become a widely accepted treatment for cataract patients with vitreoretinal diseases. We evaluated the risk factors of posterior synechia of the iris after such a combined surgery. METHODS: We selected the 149 eyes of 149 patients and reviewed the relationship between posterior synechia of the iris and preoperative condition of patients, intraoperative procedures, and postoperative findings. RESULTS: Twenty-six eyes (17.4%) developed posterior synechia; the risk ratio for female patients was 3.382 (95% CI: 1.014-11.277); in patients with uveitis history it was 9.987 (95% CI: 2.329-42.821); in patients with postoperative anterior chamber hyphema it was 17.477 (95% CI: 1.828-167.144); in patients with postoperative anterior chamber fibrin deposition it was 23.52 (95% CI: 2.938-188.299). In cases with silicone-oil tamponade the risk ratio was 8.531 (95% CI: 2.287-31.831) times higher; and in cases with C3F6 gas tamponade it was 15.786 (95% CI: 3.456-72.101) times higher than those with balanced salt solution tamponade. CONCLUSIONS: Risk factors of posterior synechia of the iris after a combined vitrectomy and cataract procedure were being female, uveitis history, silicone-oil tamponade, C3F6 gas tamponade, postoperative anterior chamber hyphema, and postoperative anterior chamber fibrin deposition.
