A gonioscopy is an examination of which part of the eye?

A gonioscopy is a specialized examination procedure that focuses on the anterior chamber of the eye, specifically examining the angle where the iris meets the cornea. This examination is crucial for assessing conditions related to glaucoma and other disorders that may affect the drainage of intraocular fluid. By using a gonioscope, an eye care professional can visualize the structures of the anterior chamber and determine whether the drainage angle is open or closed and how it may vary, which is vital in diagnosing and managing eye health. This is why the anterior chamber is the correct answer in this context. The other parts of the eye mentioned are not assessed during a gonioscopy, making them less relevant to the specific purpose of this examination.
