What is the purpose of gonioscopy?

• A. Measure intraocular pressure
• B. Examine the iridocorneal angle
• C. Assess lens clarity
• D. Determine retinal detachment

Answer: (B)

The purpose of gonioscopy is to examine the iridocorneal angle, which is the anatomical junction where the iris meets the cornea. This examination is crucial in assessing conditions related to the drainage of aqueous humor from the eye. By using a gonioscope, a veterinarian can visualize this angle directly, allowing for the identification of abnormalities such as narrow angle, open angle, or the presence of synechiae or other structural anomalies. This knowledge is particularly important when diagnosing and managing conditions like glaucoma, where the drainage of fluid from the anterior chamber is affected. Instead of just measuring pressure in the eye or assessing other structures like the lens or retina, gonioscopy provides specific insights into the outflow system of the aqueous humor, which is essential for a thorough ophthalmic examination and effective treatment planning.
