Did Edgar Degas have an inherited retinal degeneration?

Retrospective analysis of the famous painter Edgar Degas' eye disease.

A historical review and analysis based on Degas' paintings and letters exchanged between the painter and his friends and family members, as well as on the chronicles of his associates. DeGas-Musson family papers at the Howard-Tilton Library of Tulane University are also reviewed.

Degas had an eye disease that was first noticed in 1870 and that progressed throughout his life. He suffered from progressive bilateral central visual loss and light sensitivity which was most acutely recognized while he was visiting his mother's side of the family in New Orleans where he could not paint outside because of the bright sun. Edgar's maternal first cousin, Estelle Musson, also suffered gradual bilateral visual loss, and was also known to have light sensitivity early in her life. Estelle became totally blind in her early 30s. Both Edgar and Estelle were otherwise healthy and lived long lives.

It is likely that Edgar Degas and his cousin Estelle Musson had a hereditary retinal degeneration primarily affecting their central vision. Degas' retinal disease undoubtedly affected his life and his art but did not prevent him from being one of the most admired painters of all times.
