Diabetic Eye Exams in Calgary

Diabetic macular edema (DME) results from untreated diabetic retinopathy. Damage to blood vessels in the retina causes leaking, resulting in fluid entering the macula. The macula is responsible for sharp, straight-ahead vision. The excess fluid causes swelling, interfering with sight.

DME typically include symptoms:

• Floaters
• Low vision
• Blurry vision
• Double vision

Glaucoma is a leading cause of blindness in Canada. The eye condition damages the optic nerve, which translates signals from our eye to our brain. If our eye experiences too much intraocular pressure, typically because of improper fluid drainage, the pressure can cause nerve damage.

If eye damage caused by diabetes progresses, it can develop into neovascular glaucoma. Abnormal blood vessel growth from the retina blocks fluid from draining and increases pressure in your eye.

Glaucoma is treatable and has better outcomes with earlier intervention.

As damage accumulates, scar tissue builds in the back of your eye. The increasing scar tissue can slowly pull the retina from the back of your eye. Eventually, the scars can dislodge your retina, known as tractional retinal detachment.

Symptoms of retinal detachment include:

• Blurry vision
• Flashes of light
• Floaters (increased frequency or amount)
• Dark shadow or curtain over peripheral (side) or central vision

Any type of retinal detachment is a medical emergency, and you should seek attention immediately.

A cataract is a cloudy area or spot in the usually transparent lens of the eye. Cataracts can appear in one or both eyes. The affected lens area might be small with minimal vision changes, or it can cover a larger area and cause significant vision changes.

Cataract symptoms include:

• Blurry or cloudy vision
• Dull colour vision
• Light sensitivity
• Halos around lights
• Decreased night vision
• Feeling a film over the eye

Treatment options vary according to cataract size, eye health, and comfort. Your optometrist may prescribe corrective lenses or recommend surgical removal.
