Schlemm's Canal is a critical part of the eye's drainage system, responsible for draining the aqueous humor and regulating intraocular pressure. While this structure is commonly referred to as Schlemm's Canal, synonyms for this anatomical feature include Canal of Schlemm, Venous Sinus, Sinus Venosus Sclerae, and Scleral Sinus. The Canal of Schlemm is named after the German anatomist Friedrich Schlemm, who first described it in 1830. The Venous Sinus and Sinus Venosus Sclerae both describe the canal's venous nature, while Scleral Sinus refers to its location. Regardless of the term used, the importance of Schlemm's Canal as a regulator of intraocular pressure cannot be overstated.
