Between 1980 and 1999, the occurrences of ONH in Sweden increased four-fold to 7.2 per 100,000, while all other causes of childhood blindness had declined.
The main area affected is the cornea, but the issue can also spread to nearby parts of the eye, like the limbus and front eye structure, such as the iris. Since Sclerocornea is present from birth and does not develop later in life there are no short-term symptoms or signs .
The general cause of polycoria is unknown, but there are some other eye conditions that are in association with polycoria.
