Q: How does high blood pressure affect vision?
A: If the blood pressure is very high it can be called malignant hypertension and cause swelling of the macula and acute loss of vision. Otherwise hypertension can cause progressive constriction of the arterioles in the eye and other findings. Usually high blood pressure alone will not affect vision much, 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 nerve of the eye that can severely affect vision.
Q: What is diabetic retinopathy?
A: Diabetic retinopathy is a condition which can occur at any stage or type of diabetes. In fact, many times diabetes is identified during an eye exam in a person who never suspected they may have diabetes. It is caused by damage to the very delicate blood vessels within the retina. Over time, these blood vessels may start to leak blood and fluid into the retina or other areas of the eye. If the condition progresses, new vessels may begin to grow within the retina, which places the retina at risk of additional and sometimes sudden complications including internal bleeds and retinal detachment.
Q: My eye is suddenly red and irritated/painful, what should I do?
A: Whenever you get a red eye, it is very important to make an emergency eye appointment immediately with our eye doctor to see what the cause is. Some red eyes will go away with rest, but some are vision threatening and could cause blindness within 24 hours (ie. If the cause was a microorganism from contact lens wear). If you wear contact lenses, remove them immediately and do not wear until the redness subsides. Our doctor uses a high magnification slit lamp to examine your eyes to determine the exact cause of the problem and will treat accordingly. A family doctor usually does not have the necessary equipment and will treat based on your symptoms only. If your eyes need antibiotic eye drops, our eye doctor can prescribe the proper ones for your condition.
Q: How do I know if I have Dry Eye?
A: Dry eye can cause quite a few symptoms, anything from the eyes actually feeling dry to the eyes watering often, or having a burning, itchy, or irritated feeling. One of the most common symptoms is the eyes feeling gritty or like something is in your eye. Most people will often experience blurred vision since the tears, which comprise the outermost surface of the eye, are unstable.
Q: I have "spots" floating around in my eye. Should I be worried?
A: Spots and floaters are usually harmless. However, in some cases it can be a sign of a retinal detachment or bleeding. Anyone experiencing symptoms of flashing lights and flashing spots should contact our office immediately for a detailed eye exam.
Q: I suddenly see random wavy lines, zig-zagging, and/or blotches of missing vision in my vision that last for no more than 30 minutes, should I be concerned?
A: You may have just experienced an ophthalmic migraine or a migraine with aura. Usually these are harmless and indicates some sort of stress. However, it is a diagnosis of exclusion, meaning we need to always make sure that isn’t any other ocular concern within the eye itself that may be causing your symptoms. It is a good idea to make an appointment within a few days to have your vision and eye health examined. Emergency minor evaluations are usually MSP covered.
Q: What exactly is glaucoma?
A: Glaucoma is a condition in which the eye's intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it's not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.
Q: Am I a good candidate for refractive surgery?
A: Patients who are at least 18 years of age, have healthy eyes that are free from retinal problems, corneal scars, and any eye diseases are generally suitable. Many patients who are nearsighted, farsighted or have astigmatism are potential candidates. We will also discuss your lifestyle needs to help you decide if LASIK is the best alternative for you. If you would like to schedule a free LASIK consultation, please contact our office.
Q: Is there any way to prevent macular degeneration?
A: Doctors aren't sure how to prevent macular degeneration. Research suggests that ultraviolet light (and possibly blue light) factors into the problem, so sunglasses could be very beneficial. What you eat also affects your macula. Researchers know that antioxidants (vitamins A, C and E), zinc, lutein, zeaxanthin and essential fatty acids all can aid in preventing and slowing down macular degeneration. Read more about nutrition and eye health. Ask your doctor about recommended nutritional supplements. Exercising and quitting smoking might also be helpful.
Q: What are the signs of a retinal detachment?
A: A detachment of the retina may be preceded by flashes of light, increased “floater” spots in the vision or areas of “wavy, distorted vision”, etc. Most retinal detachments are painless. They can happen as a result of recent or past trauma such as falls, automobile accidents or other types of head injury. In some instances, people may be at risk for retinal detachments based on family history and increased nearsightedness. If you experience any of the above symptoms, consult your eye care professional as soon as possible.
