Q: What are specialty contact lenses?
A: Specialty contact lenses are contact lenses made for people who have trouble wearing regular contact lenses because of some type of eye health or vision issue. If you have dry eyes, or astigmatism, or kerataconus, you may have been told that you can't wear contact lenses. However, we now have new technology that allows us to fit all different types of patients with contact lenses that are comfortable, and provide great vision. These contact lenses require special fittings, performed by an eye doctor who is trained in this area, and knows what contact lenses will be best for your particular condition.
Q: What is the Optomap? Is it important?
A: Absolutely! A major part of your eye examination is when your eye doctor looks through the pupil and examines the inside of the eye. Evaluating the retina is an extremely important health test that should be done regularly, especially since many of the eye diseases we routinely diagnose do not have any symptoms. The Optomap is a fast, easy, inexpensive way of quickly taking a very thorough and detailed image of the inside of the eye. It provides several benefits to the patient. First, it creates a digital record of the inside of the eye, which can be referred to in the future to make sure the eye is healthy and stable. Second, it provides your doctor with multiple images that help them assess certain types of eye problems in ways that they cannot with the naked eye. Third, it is much more comfortable for the patient compared to the extended light sensitivity that comes with dilation. Finally, it is just plain cool. Many people are curious about what we look at during the eye examination and the Optomap allow us to look inside the eye together. Your doctor typically uses the Optomap and a special microscope to look inside the eye and assess the health of the retina. The doctor is looking for cataracts, glaucoma, macular degeneration, retinal tears, or any other eye diseases. Depending on the appointment or symptoms, your doctor may recommend Optomap, dilation, or both.
Q: How does high blood pressure affect vision?
A: High blood pressure alone does not usually affect vision directly, however hypertension is a known risk factor in the onset and/or progression of other eye disease, such as glaucoma, diabetic retinopathy, and macular degeneration, as well as blocked veins and arteries in the retina or nerves of the eye that can severely affect vision. In malignant hypertension, very high blood pressure can damage organs, and may cause swelling of the macula and acute loss of vision.
Q: What is diabetic retinopathy?
A: Diabetic retinopathy (DR) is an eye disease that can occur at any stage and with any type of diabetes. In fact, sometimes diabetes is identified during an eye exam in a person who never suspected it. It is caused by damage to the very delicate blood vessels within the retina at the back of the eye. As DR progresses, these blood vessels may start to leak blood and fluid into the retina or other areas of the eye, and new vessels may begin to grow within the retina, which can cause vision loss, and sudden complications including internal bleeds and retinal detachment.
