Abstract：
OBJECTIVE: To study and compare the predisposing factors and clinical features of pediatric, adult, and elderly rhegmatogenous retinal detachment (RRD).
METHODS: This is an observational analytic cross-sectional study in which patients with RRD admitted for surgery during 6mo period were divided into 3 age groups: pediatric (<18y), adult (18-60y), and elderly (>60y). Patients\' demographic data, clinical features, RRD predisposing factors/features including myopia (axial length ≥26.5 mm), aphakia/pseudophakia, blunt trauma, peripheral retinal degenerations, history of RRD in the fellow eye, and surgical interventions/findings were recorded and analyzed.
RESULTS: Totally 142 patients (142 eyes) were studied: 26 (18.31%) pediatrics, 86 (60.56%) adults, and 30 (21.13%) elderly. Elderly patients had a significantly higher intraocular pressures and cataracts compared to the other 2 groups (P=0.04). The RRD extent was larger in pediatric group (mostly 4 quadrants) compared to adults and elderly (mostly 2 quadrants), but it was not statistically insignificant (P=0.242). There were not statistically significantly differences in proliferative vitreoretinopathy (PVR) rate, posterior vitreous detachment (PVD) rate, number, site, shape, and size of breaks in three groups. All three groups had macular detachment in all eyes. Myopia and peripheral retinal degenerations were found to be more significant in adults (P=0.049, P=0.035, respectively), while blunt trauma was higher but insignificant in pediatric eyes (P=0.052). Pars plana vitrectomy (PPV) with silicone oil as a tamponade was the most used surgery in all groups.
CONCLUSIONS: There are no significant difference in PVR rate in pediatric eyes but a significant higher rate of total RRD. Blunt trauma is more frequent in pediatrics eyes while myopia and/or peripheral retinal degenerations are more frequent in older ages. The rate of PPV as a choice for surgery is similar among all age groups.

摘要：
目的：研究和比较儿童的易感因素和临床特征，成人,和老年孔源性视网膜脱离（RRD）。
方法：这是一项观察性分析性横断面研究，其中在6个月期间接受手术的RRD患者分为3个年龄组：儿科（<18岁），成人（18-60y），和老年人（>60y）。患者人口统计数据，临床特征,RRD诱发因素/特征包括近视（眼轴长度≥26.5mm），无晶状体/假晶状体,钝性外伤,周边视网膜变性，同胞眼中的RRD历史，记录和分析手术干预/结果.
结果：共研究了142例患者（142只眼）：26例（18.31%）儿科，86名（60.56%）成年人，和30名（21.13%）老年人。与其他两组相比，老年患者的眼压和白内障明显更高（P=0.04）。与成人和老年人（主要是2个象限）相比，儿科组（主要是4个象限）的RRD范围更大，但无统计学意义(P=0.242)。增殖性玻璃体视网膜病变(PVR)发生率差异无统计学意义,玻璃体后脱离（PVD）率，number,site,形状,和三组中断的大小。三组均有黄斑脱离。在成人中发现近视和周边视网膜变性更显著(分别为P=0.049,P=0.035),而小儿眼的钝性创伤较高，但不明显（P=0.052）。以硅油为填塞物的平坦部玻璃体切除术（PPV）是所有组中最常用的手术。
结论：小儿眼PVR率无显著差异，但总RRD率显著较高。钝性创伤在儿科眼中更常见，而近视和/或周边视网膜变性在老年人中更常见。PPV作为手术选择的比率在所有年龄组中是相似的。
