Anterior synechia is a medical term that refers to the adhesion or fusion of structures in the front of the eye, specifically the iris to the cornea or the lens. Synonyms for anterior synechia include anterior iris adhesion, iris-corneal adhesion, iris-lens adhesion, angle closure, and glaucoma. These terms are often used interchangeably to describe the same condition. Anterior synechia can occur as a result of trauma, inflammation, infection, or surgery and can lead to complications such as increased intraocular pressure and vision loss. Early diagnosis and treatment are crucial to prevent these complications and preserve vision.
