Abstract
- Coloboma is a lacking of a portion of structure of the eye. Congenital colobomas are due to some interference with the normal closure of the emoryonic cleft, the aberration lying primarily in the epiblast of the cup and occur between the time of invagination of the vesicle and closure of the cleft. The authors have experienced 3 cases of the typical colobomas of iris, ciliary body, choroid, retina and optic nerve. Two of the cases had familial history. Extracapsular cataract extraction was performed in one eye of the case and resulted in slight improvement in vision.
