AIM: To evaluate the clinical effect of vitrectomy combined with cyclodialysis repair on primary stage for complicated ocular trauma with cyclodialysis.

METHODS: The 13 consecutive cases(13 eyes)of complicated ocular trauma with cyclodialysis from January 1, 2011 to October 31, 2014, were treated and studied, including 2 contusions, 7 penetrating injuries and 4 rupture injuries. The concomitant symptoms were corneal laceration, limbus laceration, scleral laceration, hyphema, iridodialysis, mydriasis, traumatic cataract or lens dislocation, vitreous hemorrhage, retinal contusion, retinal detachment, choroid contusion, suprachoroidal hemorrhage, intraocular foreign body, etc. The preoperative visual acuity(VA)ranged from light perception(LP)to hand movement(HM)or before eye(BE).The cyclodialysis was determined by ultrasound bio-microscopy(UBM), three-mirror contact lens or was found in operation. The limits of cyclodialysis were about 2:00～6:00 o'clock. Intraocular pressures(IOP)of contusion eyes before surgeries were 5.4mmHg and 10.2mmHg. The operation opportunity was 6h～3d after injuries and the main operation stages included closing wound in cornea and sclera, vitrectomy, lensectomy, and/or removal of intraocular blood, retinal reattachment, cyclodialysis repair by suturing. The external scleral puncture and draining were carried out in suprachoroidal hemorrhage. Inert gas or silicon oil was tamponaded.

RESULTS: The ciliary body reattached in all cases determined by UBM and three-mirror contact lens. The BCVA was improved to HM/BE～4.7 and the IOP was 9.8～24.5mmHg at 1mo after surgeries, except that one eye was corneal edema after corneal laceration sutura. Retinal reattachment was determined by ultrasound or ophthalmoscope examination.

CONCLUSION: For complicated ocular trauma with cyclodialysis, the vitrectomy with cyclodialysis repair on primary stage is effective to recover the anatomic structure and preserve the available visual function.
