A child’s eye appears to have more white in one eye and less white in the other, which may be caused by congenital microkeratoconus, strabismus, and so on. Congenital microkeratoconus is a kind of congenital cornea with abnormal development. It may be due to the cornea diameter of one eye is smaller, but the size of the eyeball is unchanged, so the affected child seems to have more whites in one eye, which is prone to cataract, glaucoma and other complications. Asymmetry of the white part of the eye in both eyes may also be caused by strabismus. When the child is looking straight ahead, the black eyeball of one eye will be a bit skewed, resulting in more exposure of the white of the eye, and may be accompanied by vision loss. It is recommended that children with bilateral asymmetry be seen promptly for evaluation of their condition and treatment as prescribed by the doctor.
