Digital Retinal Screening







The health of your eyes is the most important component of your eye exam at Vision Care Specialists.  We are proud to offer Digital Retinal Screening in which a high-resolution digital photograph is taken of the back interior portion of your eye called the retina.  In most cases, the color photograph can be taken without dilating your pupils.  The image produced shows the optic nerve, blood vessels, nerve fibre layer and the macula which is the most sensitive part of the retina and is responsible for the most clear and detailed vision you have.  The screening can show abnormalities that may threaten normal vision.  It also provides invaluable baseline information to assist your doctor in determining if any changes in the health of your eye have ocurred from one exam to the next. 
The digital photographs become part of your permanent record so that your doctor can closely monitor even the slightest progression of any abnormalities.  You will be given the opportunity to see the images and get a thorough explanation of the photographs at the time of your screening.  You may even request a full color print at the time of your visit.

Comprehensive Eye Examinations






Eye doctors use a wide variety of tests and procedures to examine your eyes. These tests range from simple ones, like having you read an eye chart, to complex tests, such as using a high-powered lens to visualize the tiny structures inside of your eyes. Regardless, when you have an eye exam, it will usually take anywhere from half an hour to an hour or more, depending on the doctor, his or her caseload and the number and complexity of tests required for your eyes.
Here are the basic tests that you are likely to encounter during a routine eye exam
(your doctor also has dozens of less routine ones at his or her disposal):
  • Retinoscopy
  • Refraction
  • Autorefractors and aberrometers
  • Cover test
  • Slit-lamp examination
  • Glaucoma test (tonometer)
  • Visual field testing
