Combined vitrectomy and repair of the cyclodialysis cleft for complicated ocular trauma

Objective To evaluate the clinical effect of combined vitrectomy and repair of the cyclo-dialysis cleft for complicated ocular trauma.Method 20 cases of complicated ocular trauma, Ultrasound biomicroscopy(UBM)revealed ciliary body detachment of 360 degrees associated with 3～5 o'clock cyclodial-ysis, 6 cases of them also had recession of anterior chamber angle.Intraocular pressures(IOP)ranged from 4 to 17 mmHg before surgery, 12 cases had the IOP under 6 mmHg.Simultaneous phenomenon included mydriasis、shallow of anterior chamber、hyphema、detachment of iris root、luxation or semiluxation of the lens、traumatic cataract、vitreous opacity、detachment of retina or choroids.Result Postoperative UBM showed that ciliary body detachment disappeared and cyclodialysis clefts closed in all cases.After 1 month, IOP ranged from 13 to 21mmHg(mean 17±3.15 mmHg).During the follow-up,no detachment of retina was founded and the refract-ing media remained clear.Conclusion For complicated ocular trauma,especially with hypotony, it is necessary to receive UBM examine before surgry.The combined therapy is effective for the complicated ocular trauma with above 2 o'clock cyciodialysis.
