眼铁质沉着症导致视网膜脱离的临床观察

Clinical Observation of Retinal Detachment Caused by Ocular Siderosis

目的:观察和分析由眼铁质沉着症(OS)导致的视网膜脱离患者临床特征。方法:回顾性系列病例研究。收集2016年1月至2019年12月在武汉大学附属爱尔眼科医院收治的由OS导致的视网膜脱离并接受手术治疗的患者12例(12眼),分析其临床特征,包括最佳矫正视力、视网膜脱离复位情况以及异物存留位置。视力的比较应用秩和检验。结果:末次随访时有6例术后视力有改善,5例术后视力无明显改善,1例术后视力进一步下降。所有患者术前术后最佳矫正视力变化差异有统计学意义(Z=2.09,P=0.037)。4例合并存在视网膜裂孔的患者出现了视网膜脱离的复发。结论:OS导致的视网膜脱离患者视力预后较差,存在视网膜裂孔易导致视网膜脱离复发。

Objective:To summarize and analyze the clinical characteristics of retinal detachment patients with ocular siderosis.Methods:In this retrospective cohort analysis,12 Patients(12 eyes)with retinal detachment caused by ocular siderosis admitted to Aier Eye Hospital of Wuhan University from January 2016 to December 2019 were collected to analyze their clinical characteristics,including best corrected visual acuity,retinal detachment healing and foreign body position.Visual acuity was compared using the rank Sum test.Results:Among the 12 patients,visual acuity improved in 6(6 eyes),no significant improvement in 5(5 eyes),and decreased in 1(1 eye)at the last follow-up observation.The difference between the best corrected visual acuity of patients in this clinical observation before and after surgery was statistically significant(Z=2.09,P=0.037).Retinal detachment recurred in 4 patients who also had retinal tears.Conclusion:Retinal detachment is more likely to recur when ocular siderosis is combined with rhegmatogenous retinal detachment.
