متن کاملHypoplasia of the optic nerve.

It is usually due to a failure of development of the ganglion cell layer of the retina and results in a small but discernible optic disc with central vessels. The disc may be cupped with a peripapillary, mottled, yellowish halo corresponding to the size of the normal disc,...

Congenital anomalies of the optic disc underlie many cases of decreased vision, strabismus, and nystagmus in childhood. A comprehensive evaluation necessitates an understanding of the ophthalmoscopic features, associated neuro-ophthalmologic findings, pathogenesis, and appropriate ancillary studies for each anomaly. The subclassification of different forms of “colobomatous” defects on the basis...
