Observation of vitrectomy on complex ocular trauma with ciliary body detachment

Objective To investigate the clinical efficacy of vitrectomy in the treatment of complicated ocular trauma associated with ciliary body detachment.Methods 7 cases of severe ocular trauma was included.Amonty these 7 patients,3 cases were contusion,traumatic mydriasis,lens dislocation or subluxation and vitreous hemorrhage,4 cases were eyeball rupture,combined with retinal detachment,choroidal detachment,and subretinal or choroidal hemorrhage after debridement.7 cases of complicated ocular trauma were subjected to ultrasound biomicroscopy for determining ciliary body detachment which was 360 degrees,the range of tears was 1 ~ 2 quadrant.visual acuity(VA) ranged from light perception(LP) to hand movement(HM) Preoperative.The average intraocular pressures(IOP) was 6.03±3.25 mm Hg.Vitrectomy + lens extraction + silicone oil filling were operated on two cases of blunt trauma after ciliary body reattachment.And repair of the cyclodialysis cleft combined with vitrectomy,and also cataract removal,silicone oil filling,retina reattachment and sclera tapping were performed on the other five patients.Results After surgeries,the ciliary body reattached in all cases.VA was significantly improved Postoperatively.The mean IOP was 19.33±5.05 mmHg.Conclusion For ocular trauma with ciliary body detachment,combined vitrectomy and repair of the cyclodialysis cleft are effective to recover the anatomic structure and preserve the available visual function.
