Digital technology provides precise tools that allow your doctor to provide a complete check up of your eye health and vision. This includes a comprehensive examination of your eyes, the early detection and diagnosis of eye diseases, and prescribing treatment and monitoring plans as needed.
Digital Retinal Imaging (DRI)
Digital Retinal Imaging allows the doctor to evaluate the health of the back of the eye, which includes the retina, associated blood vessels and optic nerve head. By doing so, one can detect and monitor changes in diseases such as diabetes, high blood pressure, glaucoma, melanoma, and macular degeneration.
In addition to helping detect diseases, retinal images provide a permanent digital record. Images can be compared year after year, to assess any changes related to your eye health.
Retinal images also allow your optometrist to educate you about your eye health and explain treatment plans for any conditions that appear in the pictures.
The auto refractor is an instrument that gives the optometrist a starting point in determining your spectacle and contact lens prescription. It requires no response from the patient and therefore can be very helpful for testing children and those who don’t communicate well or are non-verbal.
The keratometer is used to measure the curvature of the front surface of the cornea. These measurements are used to diagnose conditions such as astigmatism, kerataconus, and corneal distortions. It is also used to fit contact lenses by aiding in determining the back curvature of the contact lens.
A pachymeter is an instrument that emits ultrasonic sound to measure corneal thickness. These measurements are important in the diagnosis of glaucoma. The pachymeter is also used prior to Lasik surgery to determine whether a patient has enough corneal thickness to allow a full correction of vision without making the cornea too thin.
Visual Field Analyzer or Automated Perimeter
Perimetry is a measurement of the peripheral vision. All perimeters measure sensitivity to stimuli at different locations in the visual field. It is helpful in the diagnosis and treatment of glaucoma as well as the diagnosis of various neurological problems related to diseases affecting the visual pathways within the brain.
The auto lensometer allows faster and accurate measurement of the prescription power of your glasses. After examining your eyes, the doctor can tell if there is a change in prescription and whether updating your glasses is recommended.
