AIM: To observe the clinical efficacy of vitrectomy combined with two surgical methods for the treatment of complex cyclodialysis.

METHODS: The clinical data of 42 patients(42 eyes)with cyclodialysis(the range of fracture≥60°)accompanied by injured lens and vitreoretinopathy were retrospectively analyzed. They were all examined by B-ultrasound and ultrasound biomicroscopy(UBM)before surgeries. They were divided into group A(20 eyes)with vitrectomy combined with ciliary body scleral interrupted suture and group B(22 eyes)with vitrectomy combined with ciliary body scleral continuous mattress suture. In the group A, the suture was performed first, then the vitrectomy. In the group B, the lentectomy and vitrectomy were performed first, then the continuous mattress suture suture. Postoperative visual acuity, intraocular pressure(IOP), the condition of ciliary body reset and the suture time for ciliary body reset were observed and statistically analyzed.

RESULTS: After operations, the visual acuity and IOP had no significant differences between the two groups(P>0.05). Visual acuity and the IOP significantly improved postoperatively compared with that preoperatively in both groups(P<0.05). There was no significant difference on the rate of ciliary body reset, which was 90% in group A and 86.36% in group B(P>0.05). The suture time for ciliary body reset had significant difference between the two groups(P<0.05).

CONCLUSION: Vitrectomy combined with two different surgical methods for the complex cyclodialysis is safe and effective. For keeping the lens, it is appropriate to use interrupted suture method. Continuous mattress suture method is suitable for the pseudophakic or aphakic patients, especially with wide range cyclodialysis.
