Eye Conditions

Blepharitis

Is a very common eyelid disorder characterized by red, irritated eyelid margins. This is often accompanied by dandruff-like flakes at the base of the lashes. Longstanding blepharitis may lead to plugged glands, styes, and loss of lashes. Symptoms include a feeling of dryness and irritation, redness, burning or stinging. Blepharitis is a chronic condition which requires long-term management.

Age-Related Macular Degeneration (AMD)

Is an eye disease that affects the central vision of the eye. It is the most common condition in Canada that leads to vision loss and legal blindness. However, it rarely, if ever, leads to total vision loss because it does not affect the peripheral vision. There are two types of AMD, dry and wet. The dry form is more common, progresses slowly and is usually a milder form of the disease. In the wet form new blood vessels grow at the back of the eye under the retina. If these blood vessels leak or bleed vision loss may happen suddenly and be more severe than in the dry form. You can develop the wet form if you currently have the dry form. Increasing age is the main factor for developing AMD. Smoking greatly increases your risk of developing both forms of AMD. The risk is slightly higher if you are female and Caucasian, and if you have high blood pressure or cardiovascular disease.

MacuHealth®

MacuHealth® is a vitamin that helps promote and maintain macular health. MacuHealth® contains Meso-Zeaxanthin (MZ), the only carotenoid found exclusively in the macula.  MZ, along with Lutein (L) and Zeaxanthin (Z), are the only carotenoids (of 600 available) found in the macula.  L and Z are dietary carotenoids, found in foods such as peppers, corn, egg yolks.  MZ, on the other hand, is not a part of our diet. 

MacuHealth® offers a means of building a protective layer of pigment in the eye… many consider it to be “internal” BluBlockers® for the eye, as macular protective pigment shields the macula from damaging blue light. MacuHealth® is the supplement of choice in this practice to help reduce risk and preserve vision.

Cataract

Is a cloudy lens that is inside the eye behind the pupil. When the lens becomes cloudy enough it can decrease your vision, decrease the contrast of objects, create glare problems, distort your colour perception and change your spectacle prescription. Cataracts are most often diagnosed in older individuals, though it is possible for children and young adults to develop them as well. Smoking, increased sunlight exposure, and diabetes mellitus as well as trauma and some ocular surgeries can increase your risk of developing cataracts.

Glaucoma

Is a group of diseases which cause damage to the optic nerve that connects the eye to the visual centers in the brain. They cause damage to the optic nerve over a period of time. This damage leads to a loss of side vision (tunnel vision) which can progress and in the late stages can lead to a loss of central, detailed vision. Some of the factors that put a person at risk of developing glaucoma include elevated eye pressure, increasing age, race, a family history of glaucoma, nearsightedness and prolonged use of steroid drugs (like prednisone).

Myopia or “nearsightedness”

Is a refractive error in which, because the eyeball is an elongated shape, light rays entering the eye focus in front of the retina. Those who are myopic or nearsighted have the ability to see objects clearly up close, but not those at a distance. This error can be corrected with glasses or contact lenses.

Hyperopia or “farsightedness”

Is a refractive error in which, because the eyeball is short, light rays entering the eye focus behind the retina. Those who are hyperopic or farsighted have the ability to see distant objects clearly, but not those up close. This error can be corrected by glasses or contact lenses.

Presbyopia:

Is an age related process you cannot escape! It usually becomes noticeable around the age of 40 years, when people begin experiencing blurred vision at near when reading, working on the computer, and sewing. This can be treated with corrective lenses, the most popular being progressive addition lenses. There are also bifocals, reading glasses and multifocal contact lenses.

Astigmatism

Is a refractive error usually caused by an irregularly shaped cornea. The light rays entering the eye are prevented from coming to a single focus on the retina to produce clear vision. Instead, multiple focal points occur, either behind or in front of the retina. Symptoms of astigmatism include varying degrees of blurred or distorted vision at all distances. Uncorrected astigmatism can lead to strain and headaches especially after reading or close work for long periods, and squinting. Astigmatism can be treated with corrective lenses for glasses and toric contact lenses.

Amblyopia or “lazy eye”

Is a vision development disorder. Amblyopia begins during infancy and early childhood. In most cases only one eye is affected, but in some cases reduced visual acuity can occur in both eyes. If detected early and treated promptly reduced vision can be avoided. Left untreated though, lazy eye can cause severe visual disability. One sign of amblyopia is strabismus (crossed eye or misalignment of the eye). Also, if you cover one of your child's eyes and the child starts to cry or fuss you may have covered the “good eye”. The most common cause of amblyopia is strabismus, but it can also be caused by unequal refractive errors in the 2 eyes. Strabismus: Is the failure of the eyes to maintain proper alignment and work simultaneously to direct their gaze at the same object. One eye will look directly at the object being viewed while the other eye is misaligned either inward (esotropia or “cross eyed”), outward (exotropia or “wall eyed”), upward (hypertropia) or downward (hypotropia). Strabismus can be either contant or intermittent.
