In the Normal Eye, light rays pass through the cornea (clear front portion of the eye), through the lens, and are focused on the retina (back portion of the eye). Once focused on the retina, information is transmitted by millions of tiny nerve bundles via the optic nerve to the brain where these images are translated into what we know as “sight.” When light rays are focused in front of, instead of on, the retina, we describe this condition as myopia, or nearsightedness. When the light rays are focused behind the retina, then hyperopia, or farsightedness, results.
Hyperopia -or farsightedness, has been one of the most challenging problems that we have faced. Also hyperopia is sometimes difficult for patients to understand. It is important to remember that hyperopia is basically opposite from myopia or nearsightedness. The things that cause an individual to become hyperopic are as follows:
A common eye condition most often caused by a misshaped or irregular cornea. Astigmatism is a refractive error which results in blurred or distorted vision. In most cases, astigmatism is correctable with glasses or contact lenses. The Shreveport astigmatism treatment can also require laser vision correction, performed by Dr. Lusk.
Through the natural aging process, changes occur in the lens of the eye which interfere with our ability to see clearly. The first change begins about the age of forty when the lens loses its elasticity and begins to harden. When this occurs, the lens can no longer change shape to focus properly. As a result, close objects cannot be seen clearly and reading begins to be a problem. This hardening of the lens is called presbyopia. Presbyopia treatment in Shreveport is provided by Lusk Eye Specialists and one of the most experienced surgeons, Dr. Lusk.
With a clear normal lens, the images are focused clearly on the retina. Vision is clear. With a cataract, the lens is cloudy, causing the image to become blurred and yellowed. Vision is hazy and colors become faded.
It is estimated that glaucoma is threatening the vision of two out of every hundred persons age 35 and over. Glaucoma can result in blindness, and is one of the leading causes of blindness in the United States today. We refer to glaucoma as the “silent thief” because glaucoma typically has no symptoms until partial vision loss has occurred. Loss of vision due to glaucoma is irreversible. Shreveport glaucoma treatment is provided by Dr. Lusk at Lusk Eye Specialists. It’s very important to maintain regular eye exams to prevent glaucoma or the leading complications associated with glaucoma.
Macular Degeneration – is the leading cause of impaired reading or detailed vision. It is caused by the breakdown of the macula, the central portion of the retina. Although macular degeneration causes distortion of central and color vision, side vision is not affected. Macular Degeneration treatment in Shreveport can be assited by Lusk Eye Specialists.
Diabetic Retinopathy – is the leading cause of blindness among adults. Approximately, 25% of current diabetics have some form of the disease. The risk of developing diabetic retinopathy increases with the age of the diabetic person and the duration of the disease. It is estimated that 90% of diabetics may experience some for of diabetic retinopathy over the course of their life. However, only a small percentage of those developing diabetic retinopathy have serious vision problems and even a smaller percentage become blind.
