Iris Coloboma was bilateral in 30 % cases. Choroid Coloboma was bilateral in 44.7 % of cases. Cases were unilateral in 55.3 % of cases with the right and left eye being equally represented. Microcornea and glaucoma were equally associated with uniocular and binocular cases. Nystagmus was more in binocular cases while Microphthalmos was seen more in unipolar cases
