What to do with Metal in the Eye?

Unfortunately, something that is seen in the optometrist’s office not infrequently is metallic foreign bodies in the front of the eye. The small pieces of metal become embedded in the cornea due to grinding or cutting metal while not wearing safety glasses. These metal pieces are removable from the eye with a rotating burr while the eye is numbed. However, besides being unpleasant to have and to have removed, these foreign bodies leave scars in the cornea, the severity of which depends upon how deep they are embedded.These scars will at best cause glare and at worst cause permanent decreased visual acuity or blindness. This can all be avoided by simply wearing safety glasses to protect the eyes from flying debris. Safety glasses can even be made by your eye doctor with your eyeglass prescription in them.

Ocular Anesthetics

Ocular local anesthetics are common pharmaceutical substances the optometrist may utilize during the course of a vision examination. These agents as in tetracaine or proparacaine, are derived and modified from the common drug cocaine. The cornea and the conjunctiva are readily anesthetized or numbed by these drops. The anesthetics are used in certain types of glaucoma testing, including tonometry for eye pressure determination and in pachyometry for measuring the corneal thickness. More commonly these drugs are used in diagnosing eye conditions as corneal abrasions and also in both diagnosing and removal of foreign bodies in the cornea and conjunctiva. Anesthetics, however can not be prescribed alone to relieve pain and discomfort since they actually slow down and prolong the healing process.

Will eating carrots really improve my vision?

Carrots contain a high level of beta carotene which the body converts to Vitamin A.  Our eyes depend on certain amounts of Vitamin A to maintain the health of the eyes surface as well as the proper function of the eyes retina.  Excessive amounts of Vitamin A will not increase the eyes function but too little Vitamin A can be detrimental to our vision.  Vitamin A deficiency is the leading cause of blindness in third world countries where malnutrition often leads to dehydrated corneas and retinal eye disease.  Proper diet can have a significant impact on our vision.  Eating a health balance of fruits, vegetables, fish, and nuts will provide the nutrients needed for our eyes to work to their best ability.

Why is it important to monitor the corneal endothelial cells?

Many people have asked me recently why it is important to monitor the corneal endothelial cells with a specular microscope, so I thought it would be a good topic to address.  The corneal endothelial cells have many important functions.  The most important are that they form a tight barrier to keep fluid from crossing from the aqueous (fluid in the front chamber of the eye) into the cornea and they pump excess fluid from the cornea.  This is important in allowing someone to see clearly because excess fluid can cause hazy or fluctuating vision.  Endothelial cells do not regenerate and due to the normal aging process the central cornea can lose 100 to 500 cells per year.   This number may be increased due to disease processes, contact lens overwear, surgery or trauma.   As these cells die they fall off into the anterior chamber of the eye and the remaining cells must change to accommodate the gap.  They do this by stretching or sliding into the empty position to fill the missing gap.  As they do this they change shape which is normal to a certain level, but when pushed to extremes can result in a breakdown of the cornea’s normal functions.   The specular microscope allows us to assess the health of the cells with pictures and also a numerical analysis so we may make appropriate changes to protect someone’s cornea.

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.
