This occurs when the normal flow of tears over the eyes is interrupted, or the tear film is abnormal. In many cases, dry eye syndrome is a life long problem, however, there are numerous recent improvements in Dry Eye Therapy.
Treatments can include artificial tear lubricants or in some cases blocking the tear ducts will concentrate the limited tears that are available.
Cataract is a clouding or opacity of the natural crystalline lens of the eye. This opacity may be a small spot or may cover the entire lens. When light enters the eye, it must pass through the opacity, causing vision to appear hazy and blurred. Ultimately, the best treatment is to remove the cataract lens and replace it with a clear man-made lens. This is referred to as cataract surgery.
Glaucoma is an eye disease that occurs when the pressure in the eye is too high to sustain the tissues health. It occurs most often with higher than normal pressure in the eye, but in some individuals, can occur when the pressure in the eye is considered normal. The increased eye pressure causes damage to nerve fibres that exit the eye through the optic nerve and results in vision loss. The likelihood of developing glaucoma increases with advancing age. In it’s early stages, it often does not present with symptoms, but it can be detected with a comprehensive eye examination. The most common treatment is eye drops to lower eye pressure. Other medical treatment options are also available.
Macular Degeneration is a condition in which the central part of the back of the eye loses blood circulation. It is considered a natural aging process. There is a breakdown of retinal pigment epithelium cells in the macular region. As the disease progresses, central vision diminishes. It is believed that this breakdown may be due to a lack of nutrients being supplied to the region. Additional studies have found a genetic link to this disease. Treatment can range from better nutritional management, sometimes to include a tablet containing the primary minerals and vitamins that are found lacking in many macular degenerated patients.
Diabetic Retinopathy is a condition when a diabetic person’s blood sugar levels are not well controlled. High blood sugar levels start a series of events which result in damaged blood vessel walls. These damaged blood vessels begin to leak fluid or bleed, causing the retina to swell and form deposits know as exudates. Vision can be lost if this condition is not monitored and treated.
At Eyes on the Harbour Optometrists, we carefully examine your eyes to follow and manage this and other important eye diseases.
Keratoconus is a disorder that occurs when the cornea, which is typically rounded, becomes cone-shaped. The progression is usually slow and can range from mild to severe. This distortion increases as the cornea bulges and thins. The apex of the cornea often scars, reducing the vision. Treatment of Keratoconus is most effective with specialty contact lenses which are designed specifically for the irregular corneal surface. Corneal cross-linking, to strengthen the cornea and halt corneal changes may also be recommended. If contact lens treatment is not successful, surgical corneal transplant may be necessary.
A common injury is a metallic foreign body embedded in the cornea. Grinding or drilling in iron or other metals will release particles that are hot and when they hit the eye they embed themselves in the cornea. If it is iron, as in this example, it will begin to oxidize due to the salty consistency of our tears. When the metal particle is removed, there may be a remaining rust deposit that has infiltrated the surrounding cornea. We have experience at removing these rust spots. With proper medical treatment these injuries resolve well.
Safety glasses are always recommended to prevent these types of injuries.
Blunt trauma can result in more than just the obvious bruises on the face. The retina is the nerve tissue that lines the back of the eye and senses light. There is a blood vessel layer under the retina. This is a very delicate and sensitive tissue. The concussive force to the front of the eye can travel through the eye and result in damage to the retina. If the force is great enough, it can result in a retinal detachment. Immediate examination and subsequent treatment is needed in these types of injuries.
Symptoms of "Flashes of Light" in your vision, when there is no light to explain the flashes, or a sudden onset of floaters or blurred vision, are potential symptoms of retinal detachment. In such cases, immediate evaluation is needed. If a retinal detachment occurs, the quicker it is repaired, the better the prognosis for retaining vision.
Our office staff is well trained to know how to expedite the treatment of these type of injuries.
