Diabetic Eye Disease or Diabetic Retinopathy
Diabetic retinopathy is the most common diabetic eye disease and a leading cause of blindness in American adults. It is caused by changes in the blood vessels of the retina.
In some people with diabetic retinopathy, blood vessels may swell and leak fluid. In other people, abnormal new blood vessels grow on the surface of the retina. The retina is the light-sensitive tissue at the back of the eye. A healthy retina is necessary for good vision.
If you have diabetic retinopathy, at first you may not notice changes to your vision. But over time, diabetic retinopathy can get worse and cause vision loss. Diabetic retinopathy usually affects both eyes. For more informartion, visit http://www.nei.nih.gov/health/diabetic/retinopathy.asp
Vitreous Detachment or Posterior Vitreous Detachment (PVD)
Most of the eye's interior is filled with vitreous, a gel-like substance that helps the eye maintain a round shape. There are millions of fine fibers intertwined within the vitreous that are attached to the surface of the retina, the eye's light-sensitive tissue. As we age, the vitreous slowly shrinks, and these fine fibers pull on the retinal surface. Usually the fibers break, allowing the vitreous to separate and shrink from the retina. This is a vitreous detachment.
In most cases, a vitreous detachment, also known as a posterior vitreous detachment, is not sight-threatening and requires no treatment. For more information visit http://www.nei.nih.gov/health/vitreous/vitreous.asp
Floaters are little "cobwebs" or specks that float about in your field of vision. They are small, dark, shadowy shapes that can look like spots, thread-like strands, or squiggly lines. They move as your eyes move and seem to dart away when you try to look at them directly. They do not follow your eye movements precisely, and usually drift when your eyes stop moving.
Most people have floaters and learn to ignore them; they are usually not noticed until they become numerous or more prominent. Floaters can become apparent when looking at something bright, such as white paper or a blue sky. However, a sudden increase in floaters, possibly accompanied by light flashes or peripheral (side) vision loss, could indicate a retinal detachment. A retinal detachment occurs when any part of the retina, the eye's light-sensitive tissue, is lifted or pulled from its normal position at the back wall of the eye.

So you have decided that you would like to wear contact lenses and want to know what is involved. There are many factors that must be considered before contact lens wear becomes a reality.
In this day and age nearly everyone knows someone who wears contact lenses. Undoubtedly, stories come up about benefits and problems that were experienced. It is important to remember that contact lenses are plastic medical devices placed directly on the eye and are not as innocent as they are often thought to be. With proper care and awareness contact lenses can, and should, be safe and enjoyable for the wearer. Here are some things that are considered in the wearing of contact lenses.
Compatibility - Can I even wear contacts? - First of all, are contact lenses even a good idea for you? This is the first thing the doctor will help you determine. Some factors to consider are: maturity, hygiene, dry eye, allergies, pregnancy, harsh work environment and certain systemic diseases.
Lifestyle and vision goals – How you plan to use the lenses will be important. Factors such as sporting activities, overnight (extended) wear, and presbyopia (“over 40” reading problems) will be important in the choice of lens type.
Over 40 Vision – There are many options available to address the problem with aging vision:
Multifocal lenses come in various designs and offer different focus points on the lens. This type of lens allows both eyes to have some distance and some close range available.
Monovision works by correcting the dominant eye for distance and the other eye for reading or computer range.
Reading glasses can be used over distance contact lenses if convenience is not an issue.
Astigmatism – If the amount of astigmatism is large enough it may require the use of a toric lens. A toric lens has to line up the prescription accurately and consistently in order to offer good visual acuity.
Cosmetic contact lenses are available to change the appearance of the eyes and can be prescribed without power as well. These types of lenses can help temporarily change the color of the iris, portray Halloween themes, or even allow you to promote your favorite sports team. Certain cosmetic lenses can cover up disfigurement of the eye and/or block out annoying light to the pupil in very poorly seeing eyes.
Soft Contact Lenses: We fit and have trials for a wide variety of major brands of soft spherical, toric (astigmatism), and bifocal/multifocal lenses such as: Acuvue brands, Soflens 66, Purevision, Air Optix, Extreme H2O, Avaira, Biofinity, Proclear, Focus Night & Day, and more.
Rigid Gas Permeable (RGP) Contact Lenses: We fit and carry standard and bifocal/multifocal RGP’s. Also available is the Wave contact lens that is custom fit to the contour of your cornea.
Another exciting lens that we offer is the SynergEyes hybrid contact lens. It offers the best of both worlds: the sharp vision of a rigid gas permeable lens and the comfort of a soft lens. This is achieved by placing the rigid lens in the center with a soft lens skirt. This product line also has available correction for Keratoconus, corneal distortion, and bifocal needs.
