What part of the eye is assessed during a gonioscopy examination?

1. Posterior segment

2. Interior surface of the eye

3. Anterior chamber of the eye

4. Lacrimal duct

The correct answer is: Anterior chamber of the eye

The correct answer focuses on the anterior chamber of the eye, which is crucial in assessing the angle between the iris and the cornea. During a gonioscopy examination, a specialized lens is utilized that allows the clinician to visualize this angle directly, providing important information about the drainage pathways of the eye and potential conditions such as glaucoma. The anterior chamber is significant because it is the space filled with aqueous humor, and the angle can affect intraocular pressure. Understanding the condition and structure of the anterior chamber helps guide treatment decisions for eye diseases. In contrast, the other options address areas not pertinent to gonioscopy. The posterior segment relates to the back part of the eye, including the retina and optic nerve, while the interior surface encompasses other areas that do not involve the direct examination of the drainage angle. The lacrimal duct pertains to tear drainage and is unrelated to the pressures and angles assessed during gonioscopy. Thus, the focus on the anterior chamber presents a comprehensive understanding of the eye’s anatomy relevant to this specific examination.
