Unusual coloboma of the optic nerve hea


SUMMARY
A 61-year-old male patient with bilateral, isolated and deeply excavated colobomas of the optic nerve head overed with transparent membrane with the hole and associated serous retinal detachment on the left eye is described. There were no other associated ocular or systematic features. The optic nerve coloboma of the left eye is unusual because it has characteristics and similarities with optic disc pit and morning glory syndrome which supports the unique hypothesis that these three developmental anomalies of the optic nerve are probably an expression of a single pathologic process. A case of a man of adult age with bilateral, isolated and extremely deep colobomas of the optic nerve head covered on the left eye with transparent membrane with the hole and associated with serous retinal detachment is described.

Key words: coloboma, optic nerve.
