What are Anophthalmia and Microphthalmia?
Anophthalmia and microphthalmia are birth defects of a baby's eye(s). Anophthalmia is a birth defect where a baby is born without one or both eyes. Microphthalmia is a birth defect in which one or both eyes did not develop fully, so they are small. Anophthalmia and microphthalmia develop during pregnancy and can occur alone, with other birth defects, or as part of a syndrome. Anophthalmia and microphthalmia often result in blindness or limited vision.
