Normal vision includes much more than the normal 20/20 we are accustomed to seeing and hearing about. It includes clear, comfortable vision, seen with both eyes, minus the straining, dryness, or scratchiness and tearing. Only your eye doctor, through a comprehensive eye exam can objectively determine if you are seeing optimally with or without your glasses or contacts.
A cataract is a change in the lens of your eyes, which results in decreased vision and decreased contrast sensitivity, usually brought about by aging changes in the lens structure. There are, however, cataracts which results from eye injuries, disease processes, and also at birth. Once the cataract affects the vision significantly, it can usually be surgically removed and replaced with a lens implant which can help restore patient’s vision significantly.
Glaucoma is an eye disease that progresses very slowly, affecting a patient’s peripheral or side vision and ultimately lead to blindness. It is one of the main eye diseases which is screened at each and every eye exam, through the measurement of the eye pressure, visual field screening and by checking the health of the optic nerve head.
Macular degeneration is a disease that affects the central vision, leaving the patient seeing Waviness and sometimes blind spots in their central vision. It commonly occurs in patients of light complexion in their late 60s and early 70s. It is highly associated with heavy smokers and has a slight genetic component.
Diabetic retinopathy is a complication of Diabetes that occurs inside the eye which results from damages to the blood vessels of the eye caused by rise and fluctuation of blood sugar levels. The fundus exam often reveal leaking blood vessels and bleeding that can result in permanent vision loss and blindness if left untreated. It is crucial that Diabetic patients get their eyes examined annually or sooner if indicated. Many of the signs and symptoms cannot be detected without a comprehensive eye exam from your eye doctor.
High blood pressure can also lead to changes to the eyes. Long term uncontrolled hypertension can lead to bleeding, blockage and leakage of blood vessels which can cause loss of vision. Like many other disease changes in the eyes, these signs can be seen through careful dilated eye exams.
Dry Eyes Syndrome
Dry eyes syndrome has many causes and often includes dryness, scratchiness, itching, tearing, eye strains, and eye pain. The eyes produce tears which contains three components working in conjunction with one another to help lubricate the eyes and provide a smooth, moist surface for light to enter the eye giving clear vision. When the eyes dry, one or all three components are lacking. Dryness can result from exterior factors such as wind, sun, and other environmental factors as well. Only through proper determination of the causes could there be proper treatment options.
Flashes and Floaters
Flashes of light along with floaters are symptoms of vitreous detachment and possible retinal detachment, a condition in which the vision sensitive film of the eye pulls away from the eyeball. The vitreous is the jelly-like substance in the eye that holds the eye together and gives the eye its shape. Floaters occurs when the vitreous is pulled away from the retina and floats within the line of sight, casting a shadow onto the retina. Floaters by themselves are harmless. However, floaters occuring concurrently with flashes are signs of possible retinal detachment,if left untreated can result in permanent vision loss or blind spots.
Eye allergies can often be confused with Dry Eye Syndrome and vice versa with both showing similar symptoms of scratchiness and itchiness. Often eye allergies can be diagnosed with careful examination under the microscope. Allergy drops can be prescribed to relief the itchiness and inflammation associated with eye allergies. It is one of the most undertreat eye conditions, which when treated, can provide patients with a much better quality of vision and comfort.
