Eye Tests

  • Tonometry: A test that measures pressure in the eye, called intraocular pressure. Tonometry is used to check for glaucoma.

  • Slit lamp examination: A physician or optometrist shines a vertical slit of light across your eye while examining through a microscope. This general exam can detect many eye problems.

  • Fundoscopic exam: Dilating drops first widen the pupil. By shining bright light in the back of the eye, the examiner can view the retina.

  • Refraction: If vision is impaired, a series of lenses are placed before the eyes to determine the right corrective lens prescription.

  • Visual acuity test: Reading ever-smaller-sized letters across the room identifies distance vision problems. Reading up-close can identify problems with near vision.

  • Fluorescein angiography: A fluorescent dye is used to take a sequence of retinal images.

  • Regular adult eye exam: This collection of tests may include the ones mentioned above plus others, such as eye movement.
