Tonometry is a measurement of eye pressure. Dr. Shingleton and his team use applanation tonometry, the most accurate measurement method available. After an anesthetic drop is placed in the eye, applanation tonometry is performed quickly and painlessly.
Pachymetry is a measurement of the thickness of the cornea. Thin corneas may predispose a patient to glaucoma, whereas thick corneas may occasionally be protective.
Gonioscopy allows Dr. Shingleton to directly visualize the glaucoma drainage inlet in the eye with the use of a special lens. It is quick, painless, and performed after the use of a topical anesthetic drop. The test helps differentiate between open angle and angle closure glaucoma.
Visual field tests assess your peripheral vision. Early damage from glaucoma can often be detected by this important test. Dr. Shingleton uses the latest computerized technology to assess peripheral vision. Both eyes are tested in 10 to 20 minutes and the visual field examination is repeated at varying intervals to monitor progression of glaucoma.
Nerve fiber analysis is another computerized assessment of the optic nerve that measures the thickness of the nerve fiber layer, which is damaged from glaucoma.
Optic nerve photography documents the configuration of the optic nerve. Changes that develop in the shape or pattern of the optic nerve help us to monitor glaucoma.
