Don’t Let Eye Disease Steal Your Vision

Eye disease is often undetectable without the help of an optometrist, and they can permanently damage your vision if it develops without supervision. To protect your eyesight, please visit your optometrist for an annual eye exam. Losing your vision can profoundly affect your lifestyle, but an optometrist can help manage your symptoms.

Types of Eye Disease


Glaucoma affects millions of Canadians and while there is currently no cure for this condition, testing and detection play a valuable role in glaucoma management. Cutting-edge technology and new research continues to help doctors identify glaucoma when it is in its most manageable stages. Early intervention can help prevent additional damage and vision loss.

During your regular glaucoma check at our clinic, our optometrist will check both of your eyes for pressure and associated damage to the optic nerve. The fluid inside your eye is different than tears and as pressure builds, vision is affected. Intraocular pressure and optic nerve damage are two early warning signs of glaucoma.

Open angle glaucoma, also called chronic glaucoma, is the most common type. It can also be difficult to detect since it advances slowly. An open angle chamber inside the eye causes intraocular pressure to increase.

Chronic glaucoma is caused when the drainage channels inside the eye gradually clog, preventing normal draining from occurring. This builds pressure inside the eye and gradually damages the optic nerve. The cornea, the sclera (the white part of the eye), and the iris are also affected by growing pressure.

This condition, also called closed angle glaucoma, occurs when the angle of the chamber narrows. This also prevents normal drainage of intraocular fluid. Acute glaucoma occurs suddenly with symptoms such as severe eye pain, blurred vision, headache, profuse tear production, and haloes in the field of vision. If you are experiencing any of these symptoms, you should request urgent glaucoma testing at our clinic.

Acute glaucoma is most common in people of Asian descent. Farsightedness also contributes to a person’s risk of acute glaucoma. Age is another factor that increases a person’s chance of experiencing this condition because the eye’s lens begins to naturally enlarge, resulting in a narrowed angle

Sometimes a patient may show evidence of damage to the optic nerve even though the pressure inside of the eye is within a normal range. Normal tension glaucoma is tested through examination with an ophthalmoscope. By using the ophthalmoscope to look through the pupil, an Optometrist can see the color and shape of the optic nerve. A visual field test can be used to detect blind spots even when a patient is not aware of having any. Risk factors associated with this condition include genetics, systemic heart disease, and Japanese ancestry.

This rare condition occurs when an infant’s eye drainage canals do not experience full development during the prenatal period. Excessive tearing, sensitivity to light, enlarged eyes, and cloudy eyes are indications of pediatric glaucoma. Parents should seek testing for their infant if these signs are detected.


Anyone is susceptible to conjunctivitis, particularly preschool and school-aged children, college students, teachers, and daycare workers. Pink eye always includes inflammation of the thin layer lining the inside of the eyelid, known as the conjunctiva, and covering the white part of the eye. The principal symptom of conjunctivitis is a pink appearance in the white part of the eye, which may or may not affect both eyes.

Other symptoms, depending on the type of conjunctivitis, include light sensitivity, watery, itchy eyes, burning eyes, and sticky, yellow, or greenish-yellow discharge.

There are 3 types of conjunctivitis.

Pink eye can be caused by caused by bacteria, which can cause severe damage to the eye if not treated.

Viral conjunctivitis is extremely contagious but normally improves without medical treatment in a few days. You should still visit your optometrist to ensure corneal health and prevent further complications.

Allergic conjunctivitis is a condition caused by seasonal eye irritants including dust, pollen, and pet dander. Visit your optometrist to discuss treatment options.


Cataracts develop commonly with age, and they are a leading cause of vision loss in Canada. In fact, over 2.5 million Canadians live with this disease. In healthy eyes, the crystalline lens that sits behind the front of the eye changes shape in order to focus vision. With age, however, this lens can become stiff and clouded. This clouding obscures vision by preventing light from reaching the retina.

Even though cataracts are a natural part of aging, you don’t have to live with them. If you suffer from cataracts, we can arrange referrals for treatment, which can restore your vision to its former clarity.

There are certain symptoms that can help you determine whether you have cataracts. If you do experience these symptoms, call our clinic to arrange an eye exam.

  • Sensitivity or pain caused by bright light
  • Halos and glares around lights
  • Poor central vision
  • Difficulty noticing details
  • Inability to distinguish between colors
  • Double vision
  • Increased difficulty with vision at night or in darkened rooms


Anyone can develop cataracts, but there are certain risk factors that increase one’s odds of acquiring the disease.

  • Age
  • Family history
  • Health problems such as diabetes, high blood pressure or obesity
  • Smoking
  • Drinking alcohol
  • Medications
  • Eye injury (cuts, punctures, heat or chemical burns
  • Excessive sun exposure


Surgery to remove cataracts has become increasingly common and effective. In fact, it is one of the safest and most successful procedures. Over 95% of patients report improved vision after surgery, according to the CNIB.

Your optometrist will conduct regular eye exams to monitor the progression of your cataracts. He will refer to you an experienced Ophthalmologist to remove your cataracts if surgery is deemed necessary.
