Schwalbe's line
Schwalbe's Line
Schwalbe's Line (pronounced: shvahl-buhz line) is a significant anatomical landmark in the eye. It is named after the German ophthalmologist, Friedrich Schwalbe, who first described it in the late 19th century.
Etymology
The term "Schwalbe's Line" is derived from the name of its discoverer, Friedrich Schwalbe. The word "line" refers to the visible ring-like structure that this term describes.
Definition
Schwalbe's Line is the peripheral termination of Descemet's membrane, which is the strong, transparent layer of the cornea. It is visible as a slightly raised, clear, circular line located at the corneoscleral junction, also known as the limbus of the eye.
Clinical Significance
Schwalbe's Line is an important landmark in various ophthalmic procedures and examinations. It is particularly significant in the diagnosis and management of glaucoma, as an anteriorly displaced Schwalbe's Line, known as posterior embryotoxon, can indicate a risk for the development of this condition.
