Lowy & Sewell Eye Care is now open to non-urgent as well as urgent care.

We have implemented the guidelines set by the College of Optometrists and the Ministry of Health.

  • Disinfection of touch points and equipment
  • Use of plexiglass barriers
  • All staff and patients are required to wear masks
  • A maximum number of people in the office will be strictly enforced to allow for 6 feet of spacing
  • Use of telemedicine as needed

The examination will be modified to provide the same level of care as always, but will decrease the time the Doctor is in close proximity to the patient. Advanced technology will be advised to keep this time to a minimum.

Our goal is safety while providing leading edge eye care.

Causes of Diabetic Retinopathy

What are the causes of diabetic retinopathy and long-term diabetes? Changes in blood-sugar levels is the main culprit. People suffering from diabetes generally develop diabetic retinopathy after at least ten years of having the disease. Once you are diagnosed with diabetes, it is essential to have an eye exam once a year or more.

In the early stage of diabetic retinopathy, called background or non-proliferative retinopathy, high blood sugar in the retina damages blood vessels, which bleed or leak fluid. This leaking or bleeding causes swelling in the retina, which forms deposits.

In the later stage of diabetic retinopathy, called proliferative retinopathy, new blood vessels begin to grow on the retinal. These new blood vessels may break, causing bleeding into the vitreous, which is the clear gelatinous matter that fills the inside of the eye. This breakage can cause serious vision difficulties. This form of diabetic retinopathy can cause blindness, and is therefore the more serious form of the disease.

It is not hard to greatly reduce your risk of diabetic retinopathy by following some simple steps and being aware of your overall health. The most important factor you can control is maintaining your blood sugar at a healthy level. Eating a healthy diet will help greatly in controlling blood sugar levels. A regular exercise regimen is also a great help. Finally, make sure to listen to your doctor’s instructions.
