Prospective study.
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.
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.
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.
探讨晶状体切除联合前段玻璃体切除治疗儿童白内障术后黄斑厚度的变化。

前瞻性研究。
纳入 3 至 9 岁儿童白内障患者 30 例（40 眼），其中单侧白内障 20 例（20 眼），双侧白内障 10 例（20 眼）。采用频域光学相干断层扫描获得黄斑图像。术前及术后 1、3、6、12 个月记录中央视网膜厚度（CST）和糖尿病视网膜病变早期治疗研究亚区视网膜厚度（内 1.0 至 3.0 mm 环和外 3.0 至 6.0 mm 环）。
30 例患者的 40 只眼纳入研究。术后 3 个月各亚区视网膜厚度均明显增厚（均 P <.05）。术后 3 个月 CST 与术前相比显著增厚（228.03 ± 18.58 比 240.35 ± 17.41，P =.005）；随后几个月黄斑厚度逐渐减少。术后 6 个月，内鼻、下、颞、外鼻亚区视网膜厚度仍明显高于术前（P =.048、P =.036、P =.029、P =.017）。术后 12 个月，各亚区视网膜厚度均达到术前水平。
儿童白内障术后对黄斑厚度的影响可持续 12 个月。术后内侧黄斑厚度比外侧黄斑厚度增加的时间更长。
