Glaucoma is diagnosed by several specialized eye tests including:
Tonometry to measure the intraocular pressure of the eye
Dilated eye exam, ophthalmoscopy and biomicroscopy to observe the color and shape of the optic nerve.
If anything looks suspicious, then Dr. Rodriguez performs other more sophisticated glaucoma tests such as:
Visual Field computerized test to measure the peripheral or side vision.
Gonioscopy to evaluate the drainage area inside the eye.
Pachymetry test to measure the thickness of the central cornea.
GDx to measure the Retinal Nerve Fiber Layer. The GDx is the state of the art instrument that uses a scanning laser to create an image of the optic nerve. It helps to diagnose and monitor the optic nerve for changes.
Optic Nerve Photography to record the present appearance of the optic nerve and detect any change over time.
Optical Coherence Tomography (OCT) state of the art instrument used to monitor the surface and the anatomic layers within the retina. It quantifies the Retinal Nerve Fiber Layer and the structure of the optic nerve head to determine whether there is atrophy. Thinning of the optic nerve can be a precursor to glaucoma and thinning over time can be due to glaucoma.
