- What Causes the Center of Vision to Become Blurry?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I am 58 years old and have always had good eyesight. I've never
- had to wear glasses, but lately I have been having a weird problem with my
- vision. The very center of my field of vision is blurry, while everything
- else is in focus. What could cause this? Am I going blind? Is there any
- treatment for what I have?
-

- ANSWER: Without seeing you in person, I naturally cannot make a positive
- diagnosis, but what you have described sounds like macular degeneration. The
- macula is the part of the eye that is responsible for sight in the center of
- the field of vision. Peripheral or side vision is usually not affected.
- Macular degeneration is caused by damage or the breakdown of the macula. In
- about 70% of cases, the degeneration is caused by aging. As patients get
- older, the tissues of the macula thin or break down.
- Another 10% of cases are caused by a leak or break in the blood vessels
- that nourish the back of the eye. When this happens, scar tissue can form,
- and often new abnormal blood vessels grow in the scar tissue. Central vision
- may become severely distorted and blurred.
- Other more rare forms of the condition are inherited or caused by injury,
- infection or inflammation. There is no cure for the most common age related
- form of this problem, and judging from your age, this is probably what you
- have. You can be reassured, however, that you will not go blind, since this
- problem affects only the center of vision. There are currently many low
- vision optical aids that can help improve your condition. Some of those
- available include spectacles, special hand or stand magnifying devices and
- even closed circuit television.
- The most important thing to remember is that in the majority of cases
- these aids can help the patient lead a relatively normal life, but you must
- see an ophthalmologist immediately. We can use his expertise to assure us of
- the diagnosis, and offer advice as to appropriate treatment which may be
- available to solve this problem. For example he may suggest laser treatment
- to stop the slow leak of blood from capillaries, and he will certainly be
- aware of the latest in the changing world of new developments in therapy for
- this vexing situation.
