Sommer's Sector
Sommer's Sector (pronounced: /ˈsʌmər's ˈsɛktər/) is a term used in ophthalmology to describe a specific area of the eye where glaucoma damage is often first noticeable.
Etymology
The term is named after the German ophthalmologist, Dr. Adolf Sommer, who first described this sector in the early 20th century.
