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 meant by the term allergic conjunctivitis? Is that the same as “pink eye”?
A: Allergic conjunctivitis is the clinical term for inflammation of the lining or membrane of the eye, called the conjunctiva, caused by allergic reactions to substances. Although a patient may present with red or pink eyes from excess inflammation, the common term "pink eye" can signify a broad range of conditions and can be misleading, as viruses, bacteria, fungi, and other irritating substances can cause redness resembling a "pink eye." Your eye doctor can differentiate between an allergy and a true infection, which can lead to faster healing with the right treatment.
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: I have seasonal allergies. How come my eyes are still itchy even after I take a Claritin pill?
A: You may need an anti-allergy eye drop to target the symptoms in the eye. Sometimes, oral antihistamine medications are not that effective at treating the ocular symptoms, especially within the first few days of treatment. In fact, many of them can cause dry eyes, which worsens eye discomfort. Depending on the severity of the symptoms, over-the-counter or prescription-strength eye drops can provide relief.
Q: What is Amblyopia?
A: Sometimes called Lazy eye, it is the underdevelopment of central vision in one or sometimes both eyes; it also prevents both eyes from working together.
Q: How will I know if my child's amblyopia is getting better? Is it too late to help if the problem is detected after age 6?
A: Lazy eye will not go away on its own. We have what is called electrodiagnostic testing which can determine the effectiveness of amblyopia treatment without relying on the response of the child to "tell" us how well they are seeing. Oftentimes, parents worry that the eye exam is not accurate if their child is not old enough to read the chart or is uncooperative due to anxiety surrounding an eye exam. This test is non-invasive and fast (30 minutes) and can be done right here in our office for patients of all ages, starting in infancy. We can track over time how the therapy is working and the prognosis of their vision.
Q: Does reading my smartphone or tablet in the dark damage my eyes?
A: Reading from a tablet or smartphone in the dark is okay for your eyes, as long as it's not for a long period of time. These devices have decent lighting and good contrast. However, they give off blue light, and long-term exposure may cause damage to the structures of the eye. As well, studies have shown that blue light at night disrupts melatonin production and interferes with healthy sleep cycles. Optometrists recommend wearing blue light blocking eyewear for extended digital device use, and limiting screen time during the last hour before bedtime.
Q: What are multifocal lens implants?
A: Multifocal lens implants are often used in cataract surgery to reduce the dependency upon glasses for both distance and near vision after the surgery is completed. As with other medical technology, not everyone will be a good candidate for this type of surgical implant. Patients with conditions such as diabetic retinopathy, glaucoma and macular degeneration, etc. may not receive the full benefit of these lenses. Also, some patients with corneal scarring or those with significant astigmatism are not always the best candidates for these lens implants either. Your eye care professional can help determine if this lens implant option is right for you.
Q: Can younger people get cataracts?
A: You may have a cataract from birth. Yes. Very rare but you could be born with cataracts or cataracts could be caused from injury or surgery. Some cataracts may have a little dot - congenital cataract that doesn't affect your vision and you won't even notice. The doctor may see it on exam.
Q: What are cataracts and how can they be treated?
A: Cataracts occur when the natural lens of the eye, positioned just behind the pupil, changes from clear to cloudy. This causes increasingly blurry vision that eyeglass prescription changes cannot help. When the blurriness worsens to the point that it interferes with a person’s ability to read or drive or hinders their lifestyle, the cloudy lens is surgically removed and replaced with a clear plastic one, restoring clear vision. These days, cataract surgery can take as little as 20 minutes, and with little down-time and excellent outcomes.
Q: What is a cataract? How will I know when I have one? What can be done to fix it?
A: A cataract is a clouding of the crystalline lens. The crystalline lens sits behind the iris, or the colored part of the eye. Its function is to fine tune our focusing system by changing shape as we view objects at different distances. Our lens eventually loses its ability to change shape; this is when we require reading glasses or bifocals. In addition, the crystalline lens can become cloudy or yellow as a part of normal aging. This is also known as an age-related cataract. Normal, age-related cataracts are unavoidable and everyone will develop them at some point if they live long enough. The discoloration of the lens leads to an overall blur, a decrease in contrast sensitivity, and a worsening of glare, especially at nighttime. Because they tend to develop gradually, the symptoms are often unnoticed by the patient. A yearly eye exam will allow your optometrist the opportunity to identify the cataracts and advise on how to proceed. When your optometrist decides your cataracts are affecting your vision and are advanced enough to remove, you will meet with an ophthalmologist. Cataract surgery is a safe and effective out-patient procedure that will reverse any vision loss caused by the cataracts; and it is usually covered by your medical insurance.
Q: Do I have to wait until my cataracts are "ripe" before I can have them removed?
A: No! Waiting for cataracts to get "ripe" refers to an outdated surgical technique. Today, we recommend cataract removal when your quality of vision interferes with your quality of life. It is possible to have 20/20 vision, yet be so disabled by glare from headlights or sunlight, that cataract surgery may be the right treatment. We will monitor your cataract progression and help you decide the proper timing of cataract surgery.
