Purpose: The aim of this study was to investigate the prevalance of congenital optic disc (OD) anomalies in Turkey. Methods: The 11149 eyes of 5583 patients were screened for OD 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: 11149 eyes of 5583 participants were screened. Of the 5583 participants who underwent OD examination, 186 (3,3%) were found to be abnormal. 266 of 11149 (2,38%) eyes were found OD anomalies. 98 (52,7%) were female, 88 (47,3%) were male and the mean of age was 44,05±15,73 years. The prevalence of all congenital OD anomalies was found 3,3%. The tilted disc was the most common anomaly and was found at least one eye in 46 patients (75 eyes) and 0.82% of all screened patients. Peripapillary myelinated nerve fibres was the second common anomaly and was found at least one eye in 29 subjects (35 eyes) and 0,51% of all screened subjects. Peripapillary atrophy was the third common anormality, and was found in at least one eye in 24 patients (37 eyes) and 0,42% of all screened subjects.Conclusion: 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. |
