What is gonioscopy?
Gonioscopy uses a special mirrored contact lens to view the drainage angle, the area where fluid leaves the eye. Examining this angle helps the doctor determine whether glaucoma is open-angle or closed-angle, which directly guides treatment.
Why it is important
Identifying the exact type of glaucoma is essential for choosing the right medication, laser or surgical treatment to protect your optic nerve and preserve vision.
