Renowned glaucoma researcher dies at home in Neb.

Carl Camras, a renowned glaucoma researcher who helped develop latanoprost, has died at only 55 years of age.

The Chicago native died of heart failure Tuesday at his home in Omaha.

The glaucoma eye drop latanoprost, sold under the trade name Xalatan, has become the most effective drug to treat glaucoma. Glaucoma is a leading cause of blindness, affecting more than 2 million Americans.

Camras is survived by his wife and two daughters, as well as his mother and three siblings.
