    Abstract:

    AIM: To evaluate morphological changes in the iridocorneal angle after pediatric cataract surgery. METHODS: Children who underwent primary infantile cataract surgery were included and 64 eyes from 41 children, including 18 with unilateral cataracts (18 eyes) and 23 with bilateral cataracts (46 eyes) were examined. All patients underwent two gonioscopic examinations to evaluate the iridocorneal angle, before the primary lens removal and before the secondary intraocular lens implantation. The anatomical changes in the iridocorneal angle and the relationship between intraocular pressure (IOP) and iridocorneal angle changes were also analyzed. RESULTS: The iridocorneal angle was wide in 64 eyes before and after surgery. The trabecular meshwork pigmentation, number of iris processes in every quadrant of the iridocorneal angle, and the width of the ciliary body band in the superior and inferior quadrants at the second gonioscopic examination were significantly increased compared to those at the first examination (P<0.001, P<0.05, P<0.05, and P<0.05, respectively). IOP gradually increased at 1mo after operation, and returned to the preoperative level at 3mo. However, IOP still increased significantly at 6 and 12mo. CONCLUSION: The main changes after pediatric cataract surgery include an increase in trabecular meshwork pigmentation and number of iris processes, IOP gradually increase and has positive correlation with trabecular meshwork pigmentation and anterior insertion of iris process.
