Microcoria

Microcoria is a rare, congenital eye condition characterized by small, poorly reactive pupils. It is often associated with nephropathy, a type of kidney disease.

Symptoms and Signs

The primary symptom of microcoria is small pupils that do not dilate well in response to light. This can lead to difficulty seeing in low light conditions. Other symptoms can include nystagmus, a condition characterized by involuntary eye movements, and strabismus, a condition where the eyes do not properly align with each other.

Causes

Microcoria is a genetic condition, caused by mutations in the PAX6 gene. This gene is important for the development of the eyes and other parts of the body. Mutations in this gene can lead to a variety of eye conditions, including microcoria.

Diagnosis

Diagnosis of microcoria is typically made through a comprehensive eye examination. This can include a slit lamp examination, which allows the doctor to examine the structures at the front of the eye, and a dilated eye exam, which allows the doctor to examine the back of the eye.

Treatment

There is currently no cure for microcoria. Treatment is focused on managing the symptoms and preventing complications. This can include the use of glasses or contact lenses to correct vision problems, and surgery to correct strabismus.
