Abstract：
OBJECTIVE: To determine the importance of optical coherence tomography (OCT) in patients scheduled for cataract surgery who present with no pathologies in biomicroscopic fundus examination.
METHODS: Retrospective study.
METHODS: In this study, the routine ophthalmologic examination of patients who were recommended cataract surgery was performed.Occult retinal pathologies were evaluated using OCT in patients without any pathologies in biomicroscopic fundus examination.According to whether retinal pathologies were detected on OCT, the patients were divided into two groups: normal and abnormal OCT.The findings of patients with retinal pathologies on OCT and their distribution according to age were also evaluated.
RESULTS: A total of 271 eyes from 271 patients were evaluated.The number of patients with retinal pathologies on OCT despite normal fundoscopic examination findings was 38(14.0%).Of these patients,15(39.4%) had an epiretinal membrane,10(26.3%) had age-related macular degeneration, eight(21%) had vitreomacular traction, two(5.2%) had a lamellar hole, and 1(2.6%) patient each had a full-thickness macular hole, an intraretinal cyst, and photoreceptor layer damage.The age distribution of the patients with retinal pathologies was as follows: two patients,<60 years; six patients,60-70 years;14 patients,70-80 years; and 16 patients,>80 years.The rate of patients aged > 70 years and above was 78.9%.There was no statistically significant difference between the normal and abnormal OCT groups in terms of age, gender, the presence of systemic diseases, visual acuity, central macular thickness, and cataract type or density(p > 0.05 for all).
CONCLUSIONS: In one of seven patients evaluated, retinal pathologies were detected on OCT despite normal fundoscopic examination findings.OCT can be used to detect occult retinal pathologies that cannot be detected by biomicroscopic fundus examination before cataract surgery.

摘要：
目的：确定光学相干断层扫描（OCT）在计划进行白内障手术的患者中的重要性，这些患者在生物显微镜眼底检查中没有病变。
方法：回顾性研究。
方法：在本研究中，对推荐白内障手术的患者进行常规眼科检查.在生物显微镜眼底检查中没有任何病变的患者中，使用OCT评估隐匿性视网膜病变。根据OCT是否检测到视网膜病变,将患者分为正常和异常OCT两组。还评估了OCT上患有视网膜病变的患者的发现及其根据年龄的分布。
结果：共评估了271例患者的271只眼。尽管眼底镜检查结果正常，但在OCT上有视网膜病变的患者人数为38（14.0％）。在这些病人中,15（39.4%）有视网膜前膜，10例（26.3%）患有年龄相关性黄斑变性，8人（21%）有玻璃体黄斑牵引，两个(5.2%)有一个层状孔，1例（2.6%）患者均有全厚度黄斑裂孔，一个视网膜内囊肿,和感光层损坏。视网膜病变患者的年龄分布如下：2例，<60岁；6名患者，60-70岁；14名患者，70-80岁；16名患者，>80年。年龄>70岁及以上的患者比例为78.9%。正常和异常OCT组之间在年龄方面没有统计学上的显著差异,性别,系统性疾病的存在，视敏度,黄斑中心厚度,和白内障类型或密度（均p>0.05）。
结论：在评估的7名患者中，尽管眼底镜检查结果正常,但在OCT上仍检测到视网膜病变.OCT可用于检测白内障手术前生物显微镜眼底检查无法检测到的隐匿性视网膜病变。
