Two Common Eye Ailments: Cataracts and Astigmatism

Author: Denise Villani

Everyone at some point in their life will have to deal wth some kind of eye problem. Some eye problems are easily treatable and others are much more serious. This artilce discusses two of the most common eye ailments: Styes and Astigmatisms.

A sty (sometimes spelled stye) is a tender, painful red bump located at the base of an eyelash or on, inside, or under the eyelid. A sty is caused by an infection of a clogged oil gland in the eyelid. A sty can also be caused by an infected hair follicle at the base of an eyelash.

The proper medical term for a sty is hordeolum. An external hordeolum refers to a sty that develops at the base of an eyelash involving a hair follicle of the eyelid, and a internal hordeolum refers to a sty caused by clogged glands in the eyelid. Nearly all styes, approximately 95%, are caused by the bacterium Staphylococcus aureus.

Styes will usually enlarge over several days as the infected follicle fills with pus, but most of the time it will clear up in three to seven days. The bump should not be squeezed, since this action could spread the infection and cause other styes to form.

Styes are not a serious health risk, and they do not affect vision. Although styes often recur they usually respond well to self-treatment.

Self-treatment of styes consists of applying a hot compress for 10 minutes three to four times a day. This effort may decrease pain and the stye may clear itself up. If there is no improvement after 48 hours of home treatment, a visit to the doctor my be advised and the stye may be opened and drained under sterile conditions. An antibiotic ointment or eyedrops for topical use on the eye may be prescribed.

Astigmatism is another common eye condition that affects many people. Astigmatism can be easily corrected by eyeglasses, contact lenses or surgery.

An astigmatism is an irregular curvature of the cornea. In astigmatism, the cornea is shaped more like a football, an oval shape, than the normal round shape like a baseball. This irregular shape causes two images to be focused. This type of disorder is also known as a refractive error. Nearly everyone has astigmatism to some degree. Astigmatism is usually present since birth and generally worsens as we get older. Some common causes of astigmatism are pressure from the eyelids on the cornea, incorrect posture or an increased use of the eyes for close work.

Common symptoms of astigmatism are headaches, fatigue, eyestrain and blurred vision at all distances. While these symptoms may not necessarily be the result of astigmatism, you should schedule an eye exam if you are experiencing one or more symptoms.

Treatment for astigmatism includes eyeglasses, special contacts, and certain refractive surgeries. Special contacts called toric can be specially designed for people with astigmatism. Minor degrees of astigmatism can be corrected with soft toric lenses. More serious cases of astigmatism are better corrected with eyeglasses or RGP toric contact lenses. Toric contact lenses are more expensive than normal contacts because of the extra correction provided on them.

Surgical treatments for astigmatism include LASIK Eye Surgery (Laser in-situ keratomileusis) and CK (Conductive keratoplasty) for people over 40, Astigmatic Keratotomy (AK), and Orthokeratology. LASIK reshapes the cornea by removing tissue. In Astigmatic Keratotomy, a surgeon places incisions in the periphery of the cornea to change its shape for better vision. Orthokeratology, or Ortho-K, uses RGP contact lenses to gradually reshape the cornea. The reshaping of the cornea is not permanent however and the special contact lenses will still be worn a few hours a day to keep the new shape. Only minor degrees of astigmatism are best treated with this method. There is ongoing research to develop better and more advanced methods of correction of astigmatism. New advances in materials and technology will greatly help people with astigmatism see clearly again.

      your eye colour is inherited from your parents, but the reason they are blue when born is because melanin the brown molecule has not been produced yet or exposed to the ultra violet light yet so that’s why it takes a while to show if you are going to have brown eyes, it also happens in kittens and some other animals too. as for it’s purpose it is just another distinguishing characteristic just like hair colour

    Why does my cat have a weepy eye?
    I recently adopted a kitten from the local shelter. He was tested for Feline Leukemia and other ailments and all results were normal. Last night when I brought him home, I noticed he has one eye that is very weepy. Is this something to worry about? Can it be treated at home? Someone please help!

    I have an odd eye ailment?
    This happens fairly often: I am going about my business, when suddenly I feel as thought I have something in my eye. After a little while, regardless of whether I physically attempt to remove the irritation or not, I spot a clear, string-like apparatus in my eye. I remove it, and it’s the same every time: It’s about the length of my eye, as thin as a piece of thread, very stretchy, wet, with the consistency of what feels like jelly. If I leave it out in the air, it hardens and becomes very tough.

    What is this that is in my eyes? Is it the lens shedding layers? Is it a particular illness? Any input is appreciated. All I know is that it is annoying as hell, and happens at least once every week or two.

      You omight have allergic problems with your environment. You should see your doctor and have them look at you and see if you have allergic conjuntivitis. You might have it and not even know it. They have drops you can use if this is the case.
