Gonioscopy
What is Gonioscopy?
Gonioscopy is an examination of the anterior region of your eye (between the cornea and iris). It is primarily indicated to diagnose glaucoma (build-up of pressure in the eye). To diagnose open or closed-angle glaucoma, the drainage angle, area from where fluid drains out of the eye, is examined to see if it is opened or closed. Scars and any congenital defects that may cause glaucoma can also be detected with this examination.
Prior to the procedure, your doctor may dilate your eyes and numb them with eye drops so that you are comfortable. Your doctor places a special lens lightly in front of your eye and points a narrow beam of bright light. A slit lamp or microscope is used to view your drainage angle. This procedure takes about 5 minutes and is painless. After your test, your eyes may be blurred for several hours due to the dilation.
Like all procedures, gonioscopy may be associated with certain risks such as eye infection and allergic reaction to the anaesthetic.
