Surgical results of complicated ocular trauma with cyclodialysis

Objective To explore the surgical techniques, efficacy and the management of complicated ocular trauma with anterior-posterior segment complications such as cyclodialysis. Methods Fifty-five patients (55 eyes) with complicated ocular trauma were enrolled in this study. Among them, there were 35 cases with eyeball contusion and 20 cases of eyeball rupture. Preoperative visual acuity was from no light perception to 0. 15, intraocular pressure (IOP) ranged from one to 10 mm Hg (1 mm Hg=0. 133 kPa).Cyclodialysis, vitreous hemorrhage or retinal detachment were revealed by B-ultrasound and ultrasound biomicroscopy (UBM). Cyclodialysis clefts ranged from one to 12 clock-hours. All patients underwent 3-port pars plana vitrectomy with gas/silicone oil tamponade and ciliary body reattachment by cryotherapy (cyclodialysis clefts ≤ three clock-hours) or suture fixation ( cyclodialysis clefts ＞ three clock-hours).Healing after surgical trauma, visual acuity, intraocular pressure, intraocular hemorrhage, ciliary body and retinal reattachment were followed up. Results In one month after surgery, UBM showed 54 patients out of 55 patients had good ciliary body reattachment. Gonioscopy revealed cyclodialysis still existed in one patient, and this was cured by a second surgical suture fixation. In three months after surgery, ocular trauma healed in all 55 patients, the visual acuity ranged from no light perception to 0. 15, with a best corrected visual acuity of 0.8. The ciliary body and retina had good reattachment. IOP of 52 patients was normal; IOP of three patients was still lower than 10 mm Hg. Three patients had secondary glaucoma which was treated by glaucoma surgery. Conclusions Complicated ocular trauma with cyclodialysis can be treated with vitrectomy and cryotherapy or transscleral sutures. The procedure is safe and effective.
