Congenital optic disc deformities. A clinical approach.

Different kinds of optic disc deformities are considered in this paper. These optic disc deformities include the tilted disc, the morning glory syndrome, the optic pit and the typical coloboma. All of these optic nerve deformities are probably typical and atypical optic disc colobomas. A clinical approach of these typical and atypical colobomas included different tests: angiography, electrophysiology and psychophysics. The genetic characteristics of these colobomas are considered.
