Congenital anomalies of the optic nerve head – review

Abstract

Purpose: To show the topographic features and specific measurements of the different optic nerve head congenital anomalies.Material: Confocal tomography was performed to the following optic nerve head congenital anomalies: Morning Glory Syndrome, Optic Disc Coloboma, Peripapillary Staphylomas, Megalopapilla, Optic Disc Pit, Tilted Disc Syndrome and Pseudopapilla.Methods: Examinations were performed with the Heidelberg Retina Tomograph (long wave: 680 nm), using the new standard reference plane. Each eye was also examined with fundus biomicroscopy.Results: The examinations with confocal tomography show great differences and specific features in each anomaly. Topographic data and stereometric measurements are showed for each case.Conclusion: Confocal tomography is able to demonstrate and separate the different optic nerve head anomalies, and the measure O. N. H. parameters.
