What is astigmatism?

Many people are confused by the term “astigmatism” when they visit their optometrist. Many people think it is some sort of disease of the eye. It is actually a refractive condition of the eye like near-sightedness or far-sightedness. Astigmatism causes visual distortion due to the curvature of the front of the eye, known as the cornea, or the crystalline lens within the eye. The visual distortion results from the fact that the cornea or lens are not perfectly spherical, like a baseball, but have two different curvatures, like a football. The curve of any lens is one of the main things to give it power, therefore, if the cornea or lens has two different curvatures, it has two different powers, and is bent to two different points within the eye, depending on the orientation of the light entering the eye. This causes distortion. This can be corrected by your optometrist with eyeglasses or contact lenses that have two different curvatures to perfectly counter-balance the curves in your cornea or lens.

Diabetes and Eye Exams

 

For the many people who suffer from diabetes, it is of utmost importance to have a yearly dilated eye exam. Diabetes is a disease that affects the blood vessels of the body, particularly the eyes and feet. Having a yearly dilated eye exam will allow your optometrist to directly view the blood vessels in your retina, checking for any bleeding or leaking. In severe cases of diabetic retinopathy, new blood vessels can start to grow into the retina. This is especially dangerous because these new blood vessels destroy healthy retinal tissue. If this occurs, retinal laser surgery or other treatments are necessary to stop them before blindness results. A yearly dilated exam with your optometrist will help to catch any problems earlier, when they are much easier to treat and less irreversible damage has occurred.

Watch for the Giant Papillary Conjunctivitis!!

Giant papillary conjunctivitis is a common condition in which large bumps form under an individuals eyelid.  It is an allergic response that is most common in soft contact lenses that have a longer planned replacement time frame.  The residual proteins on the lens incite the allergic reaction, which can lead to irritation and excess movement with contact lens wear.  The prevalence of GPC has decreased since disposable contact lenses have become popular.  In addition to prescribing medications and/or discontinuing contact lens wear an eye doctor may switch someone with mild to moderate GPC to daily disposable contact lenses as a viable option.

Bloody Red Eyes!

Many people come into their optometrist’s office in a panic because they have a blood red eye. This is called a subconjunctival hemorrhage (SCH).

This is similar to a bruise elsewhere on the body, but because the conjunctiva overlying the blood is clear, it looks bloody. This condition is usually no more harmful than a bruise and will resolve uneventfully with time. They are caused by trauma to the eye, anything that affects blood clotting, such as use of blood thinners, and straining, such as with lifting, vomiting, pushing during childbirth, and straining using the restroom.

Diabetes and Eye Exams

It is very important for everyone to have a yearly dilated eye exam, especially if you are diabetic. Diabetes affects blood vessels throughout the body. Two of the most common parts of the body affected are the eyes and feet. Diabetes can cause bleeding and decreased oxygen supply to the retinal tissues. This can cause new blood vessels to grow into the retina, which damage the surrounding healthy tissue. If not found and treated, blindness can result. Yearly dilated eye exams can detect changes early when treatment is easier and often more successful.

What is Presbyopia?

Presbyopia is a condition in which the lens of the eye becomes hardened.  As this happens the eye slowly loses it’s ability to focus objects from distance to near.   Individuals usually start to notice a difficulty focusing at forty and it usually worsens until the mid sixties when it stabilizes.  It will eventually affect everyone and can easily be monitored and treated with yearly eye exams.  Different treatment options may include glasses, contacts or different types of refractive surgery.

How long will LASIK vision correction last?

Lasik should ideally provide a permanent vision correction.  Once the cornea is modified it should never revert back to its original shape and should only change slightly as a person ages.  While the cornea should remain stable, there are other parts of our eyes that will continue to change as we age.  The most significant vision change people notice after Lasik is due to the lens changes that occur around the age of 40.  The lens of our eyes slowly stops being able to accommodate, or focus, as we age. This causes near vision to become blurred and brings on the need for reading glasses. This process happens to all of us whether we have had Lasik or not.  So  while a patient’s distance vision should remain clear permanently, even post-Lasik patients will  eventually need glasses again for  reading and near work.  It is importance after any corrective vision surgery to continue to have yearly eye exams.  Your doctor will be able to monitor the health of your eyes and prescribe the proper reading correction when the time comes.

What do Preservatives have to do with my eyes?

Preservatives are a common chemical preparation used in most ocular medications and contact lens solutions. These chemicals prevent bacterial growth within the bottle once it has been opened , thus preventing the spread of possible infections. These preservatives, however, can occasionally irritate and damage the eyes outer surface. There are several groups of preservatives that are tolerated quite well by our eyes without any adverse reactions. One group , the mercurials which includes thimerosal, was once a main stay in early contact lens solutions. Many patients though the use of these thimerosal based products developed an allergic sensitivity and were forced to discontinue not only the contact lens solution but even the contact lens. Today thimerosal is not a common preservative in name brand contact lens products instead there is a broad selection of excellent solutions the patient can safely use. The doctors at Rinkov Eyecare Center always consider the patients allergy history in prescribing the proper products for the care of their eyes and contact lens.

Bloodshot Eye! Why?

A common condition seen in the eye doctor’s office is a subconjunctival hemorrhage (SCH). This condition usually sends people into their eye doctor’s office in a panic, but is actually not an emergency. Patients will often wake up with bleeding over the white of their eye. This is nothing more than a bruise in the eye. In a normal bruise, the skin on top of the blood causes it to have a purplish hue. In the eye, the blood is under the conjunctiva, a clear tissue that lines the white of the eye.  Since the tissue over top is transparent, the bruise looks bright red. This can be caused by trauma to the eye, exertion from heavy lifting,  straining using the restroom, pushing during labor, coughing, and vomiting. In rare cases, it can be due to a clotting problem with the blood. This is only suspected if it occurs repeatedly. For this reason it is more common in people who are on blood thinners or NSAIDs. The treatment for a SCH is time. As with any bruise it will fade with time as the body reabsorbs the blood from the broken blood vessel.
