Gonioscopy
- Gonioscopy is a frequent test used in the evaluation of a patient with glaucoma.
- The eye must be round in order to maintain its pressure. Unlike a tire, which uses air, the eye has a fluid system for pressure. Inside the eye, there is a tissue, called the ciliary body, which pumps fluid into the eye. This fluid is drained out of the eye via the trabecular meshwork.
- Most glaucoma is caused by disease or alteration of the trabecular meshwork. This structure, which is near the front of the eye, cannot be seen under normal conditions.
- Gonioscopy consist of placing a contact lens on the front of the eye. Topical anesthesia is used in order to prevent discomfort. The contact lens allows the doctor to examine the trabecular meshwork for signs of glaucoma disease.
