Invision Eyecare recommends patients with diabetes be seen yearly for a comprehensive dilated eye examination. If you have diabetes, you are at a greater risk of eye health problems such as diabetic retinopathy and diabetic macular edema. These eye disorders tend to progress over time, often without any symptoms and if let untreated, can lead to blindness. Your visits with the Optometrist are covered annually by OHIP but your doctor will also strongly recommend that you have digital retinal images and/or Optical Coherence Tomography (OCT) scan done in conjunction with your examination. The doctors use these images to determine if there are any microscopic changes to the blood vessels in your retina and optic nerve. These images are not covered by OHIP during your comprehensive exam.
