Map-dot-fingerprint dystrophy is a common eye condition affecting the cornea, the clear front part of the eye. It is characterized by small, irregularly shaped spots and lines on the corneal surface, resembling a map or fingerprint. This condition is usually benign and often does not cause significant vision problems. Most people with map-dot-fingerprint dystrophy remain asymptomatic, but some may experience mild discomfort or blurred vision. The condition is typically diagnosed during a routine eye examination by an optometrist or ophthalmologist. Treatment is rarely needed, but artificial tears or other lubricating eye drops can help alleviate any symptoms.
