- How Do Lasers Cure Spots Before Your Eyes?

- QUESTION: When mother complained about suddenly seeing lots of spots floating
- around before her eyes, she consulted her eye doctor who rushed her off to the
- hospital for immediate treatment. As he described it, he used a laser to
- "glue" the back of her eye back in place. She is doing fine now, but can you
- tell us what happened? We do not live in the same town as Mother and find it
- difficult to get the doctor on the phone.

-
- ANSWER: Your Mother's problem was a retinal tear or detachment. The retina
- is the tissue at the back of the eye that translates the images of light into
- nerve impulses. When these impulses reach the brain, they are interpreted
- into the visual images we see. The retina is normally attached to the wall of
- the eyeball, which supplies it with oxygen and nutrients through small blood
- vessels. In front of the retina, we find the vitreous body, which is a firm,
- jelly like substance that fills a large portion of the ocular globe or
- eyeball.
- As we grow older, the vitreous becomes softer and may pull away from the
- retina causing a break or tear to occur. When fluid from the vitreous seeps
- through these breaks, it can cause the retina to detach from the wall of the
- eye. If the delicate nerve tissue of the retina loses contact with its
- nourishing arteries from the wall of the eyeball, it soon dies and vision is
- lost.
- The spots or floaters were composed of collagen fibers that tie the
- retina to the vitreous, and are a warning sign to the doctor that a tear in
- the retina may have occurred. Since early repair results in the best results,
- rapid treatment is most advisable. The laser beam passes through the clear
- parts of the eye, and is focused precisely on the edge of the tear. There,
- its intense heat causes a small burn, leading to the formation of a scar,
- which seals the tear, and fastens (or "glues") the retina back to the wall.
- This treatment is highly effective in preventing any additional vision loss,
- but sometimes must be repeated to obtain maximum results.
