This study was aimed to evaluate the difference in the ocular parameter changes following scleral buckling (SB) for rhegmatogenous retinal detachment (RRD) in different age group patients.
This prospective study included 26 eyes of 26 patients who underwent SB for uncomplicated RRD. The patients were divided into three age groups: 16-30 years (Group I), 31-45 years (Group II), and 46-60 years (Group III). Axial length (AL), anterior chamber depth (ACD), and corneal curvatures were measured preoperatively and postoperatively at 1 week, 1 month, and 3-month. The postoperative change and progression of these parameters were evaluated and compared between three age groups using nonparametric Wilcoxon signed-rank test and Kruskal-Wallis test.
At 3-month follow-up, a statistically significant postoperative AL increase, ACD decrease, and surgically induced astigmatism (SIA) were observed in all groups (Group I - 0.75 ± 0.32 mm, 0.21 ± 0.21 mm, and 1.5 ± 0.48 D, respectively; Group II - 0.79 ± 0.41 mm, 0.14 ± 0.04 mm, and 2.07 ± 1.18 D, respectively; Group III - 0.86 ± 0.33 mm, 0.16 ± 0.05 mm, and 1.56 ± 1.19 D, respectively). However, surgery-induced change for any parameter was not significantly different between the groups ( for AL [0.7955]; ACD [0.8805]; and SIA [0.5485]). Progression in postoperative changes in AL and ACD was insignificant during three follow-up examinations in all the groups. However, SIA of Group I continued to change significantly up to 3 months but stopped to change at 1 month only in Group II and III.
Age-related change in physical properties of ocular tissue does not have any major additional effect on the results of SB except that the postsurgical change in corneal curvature stops earlier in older patients compared to that in younger patients.
本研究旨在评估不同年龄组孔源性视网膜脱离（RRD）患者巩膜扣带术（SB）后眼部参数变化的差异。
本前瞻性研究纳入了26例因单纯性RRD接受SB手术的患者的26只眼。患者分为三个年龄组：16 - 30岁（I组）、31 - 45岁（II组）和46 - 60岁（III组）。术前及术后1周、1个月和3个月测量眼轴长度（AL）、前房深度（ACD）和角膜曲率。使用非参数Wilcoxon符号秩检验和Kruskal - Wallis检验评估和比较三个年龄组这些参数的术后变化及进展情况。
在3个月随访时，所有组均观察到术后AL显著增加、ACD降低以及手术诱导散光（SIA）（I组分别为0.75±0.32 mm、0.21±0.21 mm和1.5±0.48 D；II组分别为0.79±0.41 mm、0.14±0.04 mm和2.07±1.18 D；III组分别为0.86±0.33 mm、0.16±0.05 mm和1.56±1.19 D）。然而，各参数的手术诱导变化在组间无显著差异（AL [0.7955]；ACD [0.8805]；SIA [0.5485]）。在所有组的三次随访检查中，AL和ACD术后变化的进展不显著。然而，I组的SIA在3个月内持续显著变化，而II组和III组仅在1个月时SIA变化停止。
眼部组织物理特性的年龄相关变化对SB结果没有任何重大额外影响，只是老年患者角膜曲率的术后变化比年轻患者更早停止。
