目的：这项研究的目的是调查土耳其先天性视盘异常的患病率。
方法：对5570例患者的11,123只眼进行视盘异常筛查。所有患者均接受完整的眼科检查，包括最佳矫正视力，折射,球形当量，裂隙灯生物显微镜，眼内压测量，扩张立体眼底检查。数据分析使用SPSSforWindows进行，版本22.0(SPSSInc.，芝加哥,IL,美国)。
结果：对5570名参与者的11,123只眼进行了筛查。在5570名接受视盘检查的参与者中，174例患者的246只眼（3.12%，95%CI=2.66-3.58%)有视盘畸形。92人（52.9%）为女性，82（47.1％）为男性，平均年龄为44.25±15.67岁。72例（41.4%）患者为双侧，102例（58.6%）患者单侧受累。椎间盘倾斜是最常见的异常，在46例患者（75只眼）和所有筛查患者中发现至少一只眼睛。乳头周围有髓神经纤维是第二个常见异常，在31名受试者（35只眼）和所有筛查受试者的0.56％中发现至少一只眼睛。乳头状周围萎缩是第三个常见的异常，并且在24例患者（37只眼）和所有筛选对象的0.43％中至少有一只眼睛被发现。
结论：据我们所知，这是土耳其所有先天性视盘异常患病率的第一项研究。先天性视盘异常的患病率高于其他国家。
OBJECTIVE: The aim of this
study was to investigate the prevalence of congenital optic disc anomalies in Turkey.
METHODS: The 11,123 eyes of 5570 patients were screened for optic disc anomalies. All patients were underwent a complete ophthalmic examination including best corrected visual acuity, refraction, spherical equivalent, slit lamp biomicroscopy, intraocular pressure measurements, dilated stereoscopic fundus examination. Data analyses were performed by using SPSS for Windows, version 22.0 (SPSS Inc., Chicago, IL, United States).
RESULTS: 11,123 eyes of 5570 participants were screened. Of the 5570 participants who underwent optic disc examination, 246 eyes of 174 patients (3.12%, 95% CIs 2.66-3.58%) had optic disc anormalies. 92 (52.9%) were female, 82 (47.1%) were male and the mean of age was 44.25 ± 15.67 years. 72 (41.4%) patients were bilateral, 102 (58.6%) patients were unilateral involvement. The tilted disc was the most common anomaly and was found at least one eye in 46 patients (75 eyes) and 0.83% of all screened patients. Peripapillary myelinated nerve fibers was the second common anomaly and was found at least one eye in 31 subjects (35 eyes) and 0.56% of all screened subjects. Peripapillary atrophy was the third common anomaly, and was found in at least one eye in 24 patients (37 eyes) and 0.43% of all screened subjects.
CONCLUSIONS: To our knowledge, this is the first
study that the prevalences of all congenital optic disc anomalies from Turkey. The prevalence of congenital optic disc anomalies is higher than in other countries.
