Testing for Glaucoma

testing for glaucoma

Glaucoma is an eye disease that usually has no symptoms in its early stages. Without proper treatment, glaucoma can lead to blindness. The good news is that with regular eye exams, early detection, and treatment, you can preserve your sight.

 

To accurately and safely diagnose glaucoma, your eye doctor will check five factors during your examination:

Tonometry
 A measure of the pressure inside the eye (intraocular pressure or IOP)

Ophthalmoscopy
Examination of the shape and color of the optic nerve, also called a dilated eye exam

Perimetry
A test that measures your field of vision

Gonioscopy
Examination of the angle in the eye where the iris meets the cornea

Pachymetry
A measure of the thickness of the cornea
