At work or during leisure time – eye injuries are not uncommon; pointed objects and corrosive chemicals cause about 300.000 eye injuries annually in Germany.
In addition to eye injuries, some babies are born with missing or defective irises (aniridia). Aniridia is the condition of a complete or partial absence of the iris.
Regardless of traumatic or congenital aniridia, both groups suffer from severe visual impairment. Light can enter the eye almost unhindered and the glare is tremendous even in regular daylight. Contrast is perceived less and the depth of field is also reduced.
Besides the optical constrictions patiens also often suffer from the disfiguring appearance, since people often react irritated to a person with a deformed or missing iris.
About 15 % of congenital aniridia patients suffer at the same time from kidney tumors, an impaired reproductive system as well as mental disability. This is known as the WAGR Syndrome (Wilms Tumor, Aniridia, Genitourinary Abnormalities, Mental Retardation).
