GONIOSCOPY – This test examines the angle where iris meets cornea in the eye. The instrument helps in viewing the front part of the eye and to determine whether the angle is narrow or open. This test also helps in determing if any excessive pigment is blocking the drainage of humor inside the eye.
PACHYMETRY – The thickness of the cornea is checked with this test. Doctor uses ultrasonic wave instrument called pachymeter. If the central cornea thickness is thin then it is a strong predictor of Glaucoma.
VISUAL FIELD TEST – This test is also known as Perimetry and checks the complete vision of the eye. It measures the entire area seen by the person forward looking and sideways. The doctor will be able to evaluate in this if your peripheral vision is getting lost.
OPHTHALMOSCOPY – Also known as Dilated eye exam examines the shape and color of the optic nerve. It gives the complete evaluation of interior of the eye. This test will help in detecting if you have Glaucoma and of you have so how extensive it is.
There are many other tests which helps in early detection of Glaucoma like OCT (Optic Coherence Tomography), etc. You should always keep tonometry and opthalmoscopy in your routine eye tests.
