Optic Disc Anomalies with Excavation in the Disc (Optic Disc Pit, Morning Glory Disc Anomaly, Optic Disc Coloboma, Peripapillary Staphyloma)

Optic disc pits, optic disc coloboma, morning glory disc anomaly, and peripapillary staphyloma are the leading optic disc anomalies with excavation in the disc. These anomalies can be seen together with some syndromes and in this case, can be evaluated as part of the spectrum of the disease. However, when looking at each anomaly in terms of its pathogenesis and embryological origin, a different etiopathogenesis comes to the fore. In addition, ocular/systemic relations with anomalies may differ, and in this case, it is interpreted that each anomaly should be considered as a different disease. In this article, optical disc anomalies with excavation in the disc are discussed and current clinical findings, diagnosis, and treatment are revealed.
