Methods: A total of 109 eyes of 103 patients who underwent PPV for various disease entities were included. Ultrasound biomicroscopy was applied to determine the tomographic features of the ciliary body before and 1, 3, and 7 days after the surgery. All eyes were then examined once weekly for 2 months. Demographic, preoperative, intraoperative, and postoperative parameters were evaluated to assess their predictive value in the formation of postvitrectomy ciliary detachment. Results: Ciliary detachment was observed in 46 eyes (42%) after surgery and persisted for less than 3 weeks in 40 of 46 eyes. It most frequently occurred in eyes of patients with proliferative diabetic retinopathy (PDR) (64%) or retinal vascular obstructive diseases (RVO) (47%). Extensive retinal photocoagulation and retinal cryopexy positively predisposed to its formation whereas fluid-gas exchange had a protective effect. No clinical complications were observed in eyes with postoperative ciliary detachment. Conclusion: Ciliary detachment occurred frequently after PPV. A diagnosis of PDR or RVO and surgical procedures with extensive retinal photocoagulation and retinal cryopexy may have a higher incidence of its occurrence. |
