Understanding Anopia: Causes, Symptoms, and Treatment Options

Anopia is a rare condition where there is a complete absence of the iris, which is the colored part of the eye. It is also known as "aniridia" or "absence of the iris."

The iris is the ring-shaped muscle that surrounds the pupil and controls the amount of light that enters the eye. In people with anopia, the iris is either completely missing or greatly reduced in size. This can cause a range of vision problems, including blurred vision, sensitivity to light, and increased risk of eye infections.

Anopia can be caused by genetic mutations or can be present at birth due to certain syndromes or injuries. It is a rare condition, affecting only about 1 in 50,000 to 1 in 100,000 people worldwide. There is no cure for anopia, but glasses or contact lenses can help improve vision, and surgery may be necessary to correct other eye problems associated with the condition.
