The Centervue retinal screening lasts a total of 5 minutes. It takes a picture of the inside of the back of your eyes. Your doctor will review your images with you. If any problems are detected, appropriate treatment options will be discussed. Normal fundus photos will serve as a baseline reading to detect any small changes in the future.
This screening is not covered by your medical insurance because most plans do not cover preventive care. But with a small out-of-pocket expense, this test can tell you a lot about your health.
Think of a retinal screening as a wellness test: it documents the status of your health for future reference. This will help your doctor notice small changes as the years go by. Catching subtle changes early is crucial in preventing pathologies. The retina is a window into your general health.
Oculus Visual Field
The Oculus Easy Field visual fields instrument examines how your eyes and brain works together. The machine does this by checking the health and function of the visual pathways from the eyes back to the brain, as well as the vision portion of the brain. Small areas of missing vision can be screened with this device. Because vision is overlap by your right and left eyes, these early stages of vision lost is not noticed.
Diseases that manifest losses of visual fields includes glaucoma, multiple sclerosis (MS), stroke and pituitary tumors as well as many others. Subtle losses of visual fields may be the first sign of disease.
This screening is also not covered by your medical insurance because most plans do not cover preventive care. But with a small out-of-pocket expense, this test can tell you a lot about your health.
The Topcon CT-80 Non-Contact Tonometer gently measures the pressure of your eye with a soft puff of air. "Air puff" test – where an automated instrument discharges a small burst of air to the surface of your eye. Based on your eye's resistance to the puff of air, the machine calculates the pressure inside your eye – called your intraocular pressure (IOP).
Though the air puff test can be startling, nothing but air touches your eye during this measurement and there's no risk of eye injury from the procedure. Intraocular pressure (IOP) is important because it is one of the screening methods used to detect glaucoma.
Elevated pressure or a pattern of increasing pressure over a period of time may indicate glaucoma. IOP is also used to assess appropriate treatment regimen.
The Topcon KR-8800 Auto-Refractor automatically determines a tentative prescription for glasses and corneal curvature measurements helps to determine the proper contact lenses fit.
An autorefractor evaluates the way an image is focused on the retina, where vision processing takes place, without the need for you to say anything. This makes autorefractors especially useful when examining young children or people who may have difficulty with a regular ("subjective") refraction. Often, the results obtained from an autorefractor are verified and refined with a manual subjective refraction during the exam to determine your eyeglasses prescription.
This is where your "20/20" experience happens! During a refraction, the doctor puts the phoropter in front of your eyes and shows you a series of lens choices. You will then be asked which of the two lenses in each pair ("1 or 2,") make the letters on the wall chart look clearer.
Based on your answers, your doctor will determine the amount of myopia (nearsightedness), hyperopia (farsightedness) and/or astigmatism you have, and the eyeglass lenses required to correct these vision problems (which are called refractive errors).
This instrument, is a microscope the doctors would use to examine and check the health of the front part of the eye as well as the back of your eye. Patients are seated comfortably in with chin and forehead rested in.
Patients are then directed to look in certain areas. If your eyes are also dilated, the doctors can look in the back of your eyes and check for any damages or diseases to your retina.
