Q: What causes Keratoconus?
A: The characteristics of keratoconus have been known for at least 200 years, but the specific causes are still undetermined. Several theories have been proposed. One scientific theory is that keratoconus is genetic in origin. About 7% of patients have other family members with the disease. Another view holds that keratoconus is a degenerative condition perhaps linked to the altered balance between enzymes and inhibitors within the cornea. Keratoconus may also be secondary to some disease processes. A hypothesis has also been proposed that keratoconus may involve the endocrine system (hormones) since the condition is often diagnosed in young people at puberty or in their late teens. While the exact cause of keratoconus has not yet been determined, research into keratoconus continues and new treatment options are continually under development.
Q: Does your office treat any eye related problems that children may have?
A: Any health concern related to the eye and the surrounding area can be taken care of in our office. Red eyes, allergies, blurred vision etc can all be medically related problems, and we can treat them in our office.
Q: What exactly is astigmatism?
A: Astigmatism is usually caused by an irregularly shaped cornea, the front surface of the eye. Instead of being a perfect sphere, like a ball bearing or a marble, it can become a little more like a football, being more curved in one direction than the other. This brings light into focus at more than one point on the retina at the back of the eye, resulting in blurry or distorted vision.
Q: What are the common symptoms of OCULAR allergies?
A: Excessive tearing, frequent eye rubbing, constant irritation especially in the corners of your eyes closest to the nose, lid swelling or puffy eyes, and red or pink eyes are some of the most common ocular allergy symptoms.
Q: What is the difference between seasonal and perennial allergies? How would I know the difference?
A: Simply put, seasonal allergic conjunctivitis (SAC) is a more common and persistent form of ocular allergies that occurs during changes in season, which include outdoor weeds, grasses, and tree pollen. Whereas perennial allergic conjunctivitis (PAC) is a more mild and chronic presentation that occurs year-round from common indoor allergens, such as animal dander, molds, fungus, and even dust mites.
Q: My previous eye doctor told me I have “stigma!” Am I going to go blind?
A: Stigma is actually referring to a type of refractive error known properly as astigmatism, and no, you will not go blind from having astigmatism; it is not a disease. In fact, this condition is relatively common. There are three types of refractive errors: myopia, hyperopia and astigmatism. The former two are also known to as nearsighted (cannot see far away) and farsighted (cannot see up close). Astigmatism is simply the third category; it can affect both the near and far vision. Much like nearsightedness or farsightedness, astigmatism is corrected using glasses or contacts. Technically speaking an eye with astigmatism requires two different prescriptions to correct vision in one eye, due to the more oval shape of the cornea. For contact lens wearers, this will require a more specialized contact lens and a more in-depth fitting procedure.
Q: What is blue light and why is it dangerous?
A: Blue light is part of visible light and has a wavelength close to UV rays on the light spectrum. It is naturally produced by the sun, given off by fluorescent light bulbs, and emitted by LED screens on computer monitors, tablets, and smartphones. The eye's natural filters do not block blue light and chronic exposure may increase your risk for age-related macular degeneration. Evidence also shows that blue light exposure can lead to sleep problems.
Q: My doctor says I have a cataract, but he wants to wait a while before removing it. Why?
A: A cataract usually starts very small and practically unnoticeable, but grows gradually larger and cloudier. Your doctor is probably waiting until the cataract interferes significantly with your vision and your lifestyle. You need to continue to visit your eye doctor regularly so the cataract's progress can be monitored. Some cataracts never really reach the stage where they should be removed. If cataracts are interfering with your vision to the point where it is unsafe to drive, or doing everyday tasks is difficult, then it's time to discuss surgery with your eye doctor.
Q: Is wearing makeup or eye mascara harmful to my eyes?
A: Wearing makeup is not harmful to your eyes, if it's done properly. Eyeliner should be worn on the outer eyelid margin, not the inner margin where it can cause issues with infections and dry eyes if it blocks the openings of the meibomian glands, which secrete oil to keep your tears on your eyes longer. Additionally, all eye makeup should be removed every night before bed. We all have bacteria that lives on our skin, which is normal. However, the bacteria and mites that live in and around our lashes like to feed on the dried mascara and eyeliner overnight, which can cause bacterial overgrowth and infections. Replace your mascara every 3-4 months: that bacteria gets in the tube, too!
Q: Why does allergy season affect my eyes?
A: It’s that time of the year for allergies, and for those who suffer, it’s more than just sneezing. It can mean months of itchy, watery, and puffy eyes. Because many of the allergens are in the air, they easily get into the eyes and cause problems. For some people, a sudden case of red and watery eyes can feel like an infection when really, it’s just allergies. Eye allergies, known as “allergic conjunctivitis”, can often be treated with over the counter medication, but for some, it is not enough. Let us help you manage your allergies this season.
