[18] Congenital or infantile glaucoma: [18] In Congenital glaucoma, the cornea becomes edematous, cloudy, and enlarged. Treatment should be done to reduce Intraocular pressure.
On photographs taken using a flash, instead of the familiar red-eye effect, leukocoria can cause a bright white reflection in an affected eye.
