A comprehensive eye exam is a thorough examination of the eyes and visual system performed by an ophthalmologist or optometrist. The exam usually includes several different tests and procedures to evaluate the health and function of the eyes, including:
- Visual acuity test: This test measures the sharpness of a person's vision by determining how well they can read letters on a chart from a distance.
- Refraction test: This test determines the glasses or contact lens prescription needed to correct any refractive errors (nearsightedness, farsightedness, or astigmatism)
- Slit-lamp examination: This test uses a special microscope to examine the front of the eye, including the cornea, iris, and lens.
- Tonometry: This test measures the pressure inside the eye, which is important in the diagnosis and management of glaucoma.
- Dilated fundus examination: This test uses special eye drops to dilate the pupils, allowing the ophthalmologist to examine the retina, the back of the eye, and the optic nerve.
- Visual field test: This test measures the extent of a person's peripheral vision.
- Color vision test: This test is used to determine if a person has any color vision deficiencies
- Retinal imaging: This test uses a special camera to take pictures of the retina, the back of the eye, which is important in the diagnosis and management of diseases such as diabetic retinopathy and age-related macular degeneration.
The comprehensive eye exam is important for detecting and managing eye diseases and disorders early, as well as for determining the correct eyeglasses or contact lens prescription.
