Abstract

Abstract : Macular thickness in each subfield was significantly increased after pediatric cataract surgery, with a peak at 3 months, and the difference lasted until 12 months. Abstract : Purpose: To explore the macular thickness changes after lens removal combined with anterior vitrectomy for pediatric cataract surgery. Setting: The Eye Hospital of Wenzhou Medical University, Zhejiang, China. Design: Prospective study. Methods: Thirty children (40 eyes) aged between 3 years and 9 years with pediatric cataracts, including 20 children (20 eyes) with unilateral cataracts and 10 children (20 eyes) with bilateral cataracts, were enrolled. Spectral-domain optical coherence tomography was used to obtain macular images. Central subfield thickness (CST) and retinal thickness in the Early Treatment Diabetic Retinopathy Study subfields (inner 1.0 to 3.0 mm annulus and outer 3.0 to 6.0 mm annulus) were recorded preoperatively as well as at 1, 3, 6, and 12 months postoperatively. Results: Forty eyes of 30 children were included. Retinal thickness in every subfield significantly thickened at 3 months postoperatively (all P < .05). CST significantly thickened compared with preoperative levels (228.03 ± 18.58 vs 240.35 ± 17.41, P = .005) at 3 months postoperatively; macular thickness gradually decreased in the following months. At 6 months postoperatively, retinal thickness in inner nasal, inferior, temporal, and outer nasal subfields remained significantly thicker compared with preoperative levels ( P = .048, P = .036, P = .029, and P = .017, respectively). At 12 months, the retinal thickness in all subfields reached the preoperative level. Conclusions: The influence on macular thickness lasted until 12 months after pediatric cataract surgery. The inner macular thickness increased for a longer time than the outer macular thickness postoperatively.
