Walsh & Hoyt: Optic Disc Dysplasia

Optic disc dysplasia is a term that connotes a markedly deformed optic disc that fails to conform to any recognizable diagnostic category. The distinction between an nonspecifically anomalous disc and a dysplastic disc is somewhat arbitrary and based primarily upon the severity of the lesion. For instance, in the past, the term optic disc dysplasia was applied to cases that are now identified as the morning glory disc anomaly or papillorenal syndrome. Conversely, many dysplastic optic discs have been indiscriminately labeled as optic disc colobomas. New variants of optic disc dysplasia continue to be recognized.
