Gonio

Gonio is a term used in multiple contexts, deriving from the Greek word gónía meaning angle. In science and medicine, it appears as a combining form in terms related to angles and their measurement, most notably in devices such as the goniometer and in procedures such as gonioscopy.

In ophthalmology, “gonio” is a common shorthand for gonioscopy, an examination of the iridocorneal angle of the eye. The procedure uses a specialized lens or prism to visualize the angle between the iris and cornea, helping assess angle width and configuration. Gonioscopy is important for diagnosing and managing glaucoma, as angle status influences treatment decisions and risk assessment.

Gonio is also the name of a coastal locality in Adjara, Georgia, near Batumi. The area is known for the Gonio Fortress, also called Apsaros Fortress, a Roman-era site overlooking the Black Sea. This historic site, together with the surrounding area, attracts visitors and researchers interested in ancient fortifications and regional history.

Summary form: Gonio can refer to the linguistic root related to angles, to medical terminology and procedures involving angle assessment (notably gonioscopy in ophthalmology), or to a geographic location in Georgia notable for the Gonio Fortress. The common thread is the concept of angle or angular measurement, whether in language, science, medicine, or geography.
