Gonioscopy

Gonioscopy is a crucial diagnostic procedure in ophthalmology used to examine the iridocorneal angle—the area where the iris meets the cornea. It helps in assessing conditions like glaucoma by evaluating the drainage angle of the eye. During gonioscopy, a special lens is placed on the patient's eye after numbing it with eye drops. This lens allows the ophthalmologist to visualize and classify the angle structures—Schwalbe's line, trabecular meshwork, scleral spur, and ciliary body—based on their appearance. The procedure helps determine whether the angle is open, narrow, or closed, influencing treatment decisions. Gonioscopy is essential for accurate diagnosis and management of various types of glaucoma, guiding therapeutic approaches such as medications, laser therapy, or surgery aimed at reducing intraocular pressure and preserving vision. Regular gonioscopic examinations are crucial in monitoring disease progression and adjusting treatment plans as needed.
