The technique and observation of closed stitching recovery for Iridodialysis

Abstract

Objective Iridodialysis is a common complication of closed incarcerated ocular trauma. Re-covery by reduction is the most effective stitching method. There are two methods of stitching:corneoscleral edge incision method and closed stitching method. The author has achieved better results with closed stitching meth-od. Methods In the cases of Iridedialysis,there are various types of complications,e, g. hyphema and pigmen-ted retina inflammation. The surgery is better performed after treatment in (3-7 days after treatment). Perform stitching fixation beneath the sclera flap on the cornenscleral edge of Iridedialysis. Based on the length of separa-tion,determine the counts of stitching (1-4 stitches) ,bury the end of stitches under the selera flap,with the re-duction and recovery of conjunctival flap. Results Our hospital has treated 32 cases of Iridodialysis,with com-plete recovery in each case. After the surgeries,26 cases were found with centralised pupils,4 cases with cent-ralised pupils shghtly oval-shaped,2 cases with deviated pupils,2 cases with angle recession and ocular hyper-tension. After sugeries,21 cases are found with adjusted vision of 0.5-1.0 (65.6%),6 with 0.3-0.4,2 with 0.1-0.2 (6.2%),1 with below 0.1 (3.1%). The cases with poor eye visions suffer from ocular hypertension, angle recession,vitreous hemorrhage,and etc. Conclusion For the Iridedialysis caused by incarcerated closed ocular trauma, the stitching fixation beneath sclera flap can be performed at an appropriate time after treatment to achieve desirable results. Therefore, this surgery method can be applied. The closed stitching method can mini-mise the stimulation to eye balls with rapid recovery of eye vision, and formation of a centralised pupil in a satis-factory shape of round or near-round. However,recovery of eye vision is not as good for those cases with serious eye trauma resulting in vitreous hemorrhage, angle recession, retina mutation, and visual neuro trauma.
