ORPHA:98947Morphological anomaly
Also called Coloboma of optic papilla
What it is
Coloboma of optic disc is a rare, genetic, developmental defect of the eye characterized by a unilateral or bilateral, sharply demarcated, bowl-shaped, glistening white excavation on the optic disc (typically decentered inferiorly) which usually manifests with varying degrees of reduced visual acuity. It can occur isolated or may associate other ocular (e.g. retinal detachment, retinoschisis-like separation) or systemic anomalies (e.g. renal).

ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
