Damaging the optic nerve, Glaucoma impairs vision and eventually leads to loss of vision. It is the leading cause of blindness among Canadians and has no known cure. Glaucoma usually appears in people over 40 years old, but it can occur at any time. With early diagnosis and treatment, Glaucoma can be controlled. Bayshore Optometric Clinic recommends regular eye exams to minimize your risk of Glaucoma.
Age-Related Macular Degeneration (AMD)
AMD is related to aging and targets high risk groups like smokers and those who have had excessive exposure to UV rays. AMD has two varieties “wet” and “dry.” The most common type is dry form with no known cure. Wet form responds to certain treatment if diagnosed early enough. Once again regular eye exams are vital in ensuring early detection and treatment for AMD. As AMD is the number one cause of blindness among Canadians, it is particularly important for people in their senior years to receive eye exams.
When the cornea becomes thin and distorted, bulging forward like a cone, it is a condition called keratoconus. This disease causes people’s vision to double while still remaining clear. It often appears during the late teen years, the 20s, or even early 30s. There is no known cause, but can be hereditary. It is also linked to chronic eye rubbing and Down syndrome. For additional information on keratoconus, please visit the Ontario Association of Optometrists (OAO).
Retinal detachment is a condition where the retina has either partially or completely peeled away from the back of the eye. The retina stops working once detached and light signals cannot get back to the brain for processing. Vision loss occurs in degrees depending on the severity of the detachment. Some symptoms of retinal detachment include flashing lights or floating spots in the vision. You might even feel as if a “curtain” is coming down into your field of vision. There are some patients who do not experience any symptoms at all. Read more about retinal detachment on the Ontario Association of Optometrists website.
A cataract clouds the eye’s natural lens behind the iris and pupil. For people over 40, cataracts become the most common cause of vision loss and blindness. Cataracts come in various types including:
This type of cataract appears at the back of the lens, occurring at a greater rate in people with diabetes, high farsightedness, retinitis pigmentosa, and those taking high doses of steroid medication.
A symptom often associated with aging, the nuclear cataract forms in the central zone or nucleus of the eye’s lens.
Occurring in the lens cortex, a cortical cataract refers to the white, wedge-like opacities that begin in the periphery of the lens and work their way to the centre.
► Corneal Ulcer
A corneal ulcer is an erosion or open sore in the outer layer of the cornea, often caused by infection related to bacteria, viruses, fungi or a parasite. Other causes include severe dry eyes, scratches on the eye's surface and inflammatory disorders.
