In the present study, the incidence and risk factors of lens-iris diaphragm retropulsion syndrome (LIDRS) were evaluated.
Patients who underwent cataract surgery using phacoemulsification between June 2014 and December 2014 were included in the study. The preoperative ocular biometric and intraoperative surgical parameters were examined. The incidence of LIDRS and various risk factors were analyzed using an independent t-test, Pearson's chi-square test, and univariable and multivariable logistic regression analyses.
Among 124 eyes of 124 patients, 100 (80.6%) had no LIDRS and 24 (19.4%) had LIDRS. LIDRS occurred in 13 of 31 vitrectomized eyes (41.9%) and 11 of 93 non-vitrectomized eyes (11.8%). Based on univariable analysis, age (odds ratio [OR], 0.920; p = 0.001), vitrectomized eye (OR, 5.038; p = 0.001), spherical equivalent (OR, 0.778; p < 0.001), axial length (OR, 1.716; p < 0.001), anterior chamber depth (OR, 3.328; p = 0.037), and 3.0 mm vs. 2.2 mm incision size (OR, 4.964; p = 0.001) were statistically significant risk factors associated with the development of LIDRS. Conditional multivariable logistic regression showed that vitrectomized eye (OR, 3.865; 95% confidence interval [CI], 1.201 to 12.436; p = 0.023), long axial length (OR, 1.709; 95% CI, 1.264 to 2.310; p = 0.001), and 3.0 vs. 2.2 mm incision size (OR, 3.571; 95% CI, 1.120 to 11.393; p = 0.031) were significant independent risk factors associated with LIDRS.
LIDRS is a relatively common occurrence and was found to be associated with vitrectomized eye, long axial length, and larger incision size. Evaluating risk factors prior to cataract surgery can help reduce associated morbidity.
在本研究中，评估晶状体虹膜隔后移综合征（LIDRS）的发生率及危险因素。
纳入2014年6月至2014年12月期间接受超声乳化白内障手术的患者。检查术前眼部生物测量参数及术中手术参数。采用独立样本t检验、Pearson卡方检验、单因素和多因素logistic回归分析LIDRS的发生率及各种危险因素。
124例患者的124只眼中，100只（80.6%）未发生LIDRS，24只（19.4%）发生LIDRS。31只接受玻璃体切割术的眼中有13只（41.9%）发生LIDRS，93只未接受玻璃体切割术的眼中有11只（11.8%）发生LIDRS。单因素分析显示，年龄（比值比[OR]，0.920；p = 0.001）、接受玻璃体切割术的眼（OR，5.038；p = 0.001）、等效球镜度（OR，0.778；p < 0.001）、眼轴长度（OR，1.716；p < 0.001）、前房深度（OR，3.328；p = 0.037）以及3.0 mm与2.2 mm的切口大小（OR，4.964；p = 0.001）是与LIDRS发生相关的具有统计学意义的危险因素。条件多因素logistic回归显示，接受玻璃体切割术的眼（OR，3.865；95%置信区间[CI]，1.201至12.436；p = 0.023）、长眼轴长度（OR，1.709；95%CI，1.264至2.310；p = 0.001）以及3.0 mm与2.2 mm的切口大小（OR，3.571；95%CI，1.120至11.393；p = 0.031）是与LIDRS相关的显著独立危险因素。
LIDRS是一种相对常见的情况，且发现与接受玻璃体切割术的眼、长眼轴长度和较大的切口大小有关。白内障手术前评估危险因素有助于降低相关并发症的发生。
