Shannon Bream, a Fox News anchor, has a condition called corneal map-dot fingerprint dystrophy, which is a type of epithelial basement membrane dystrophy. She was also diagnosed with chronic erosion syndrome, which is a chronic condition that causes the cornea to erode. This condition causes extreme dry eye, which left her in pain all the time and even suicidal. Dr. Clinch, an ophthalmologist, diagnosed her with this condition and treated her with Muro 128, which has helped her manage her symptoms. Corneal map-dot fingerprint dystrophy is the most common type of corneal dystrophy, affecting 2 percent of the population.
