Unusual coloboma of the optic nerve hea
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.
