Gonioscopy in Eye Care

Anerior Chamber Angle

Gonioscopy is a specialized eye examination technique used to visualize the anterior chamber angle structures of the eye, which are crucial in the diagnosis and management of glaucoma and other ocular conditions. The anterior chamber angle, where the cornea and iris meet, contains important structures such as the trabecular meshwork, Schlemm's canal, and the ciliary body. These structures are essential for the regulation of intraocular pressure (IOP) by facilitating the drainage of aqueous humor from the eye. By using a gonioscope, a mirrored lens that allows a clear view of the angle, eye care professionals can assess the openness of the angle, identify abnormalities, and determine the type of glaucoma present. This examination is essential for distinguishing between open-angle and angle-closure glaucoma, guiding appropriate treatment strategies, and preventing vision loss. Understanding the anatomy and function of the anterior chamber angle structures through gonioscopy is therefore a fundamental aspect of comprehensive glaucoma care.
