Eye puncture then bleeding?!


Question: Eye puncture then bleeding.?
I'm fine now as this accident happened when I was a kid. I just want to know if this lead to my near-sightedness.

When I was a kid, maybe 15 years ago, I got hit by a tennis racket accidentally. The blow hit my eye, but I didn't feel pain, it went numb.

I ran to a mirror and saw my eye was bleeding. Now that i think about it, I wasn't scared or in panic. I went to my mother and told her what happened. They were the ones that panicked. But after telling them that I'm not blind nor was my vision blurred, they calmed down a little.

Not that they can do anything about it, we were up in the mountains for a summer vacation. And any hospital would be hours away. A little wash and lots of rest later, I finally let them examine it. A millimeter beside my iris was a red spot. It was clearly a wound, and were relieved it was just the white part of my eye that got injured.

Years later, I developed some uncontrollable blinking. The doctor said it's because my tear ducts/glands/whatever was damaged, and that I need artificial tears. Well it solved itself after a while and I was normal.

By high school I started having difficulty reading from afar. I didn't relate my problem to that incident and thought it was just my time to wear glasses.

The red spot is now just a brown smudge in my eye, but it proves that I just survived an almost "blinding" accident. Thank God.

But now that I think about it... if I was able to have my eye get checked thoroughly right after being hit with that tennis racket, would I have had a normal pair of eyes.? Health Question & Answer


Answers:
I am no optometrist, but here's my view anyway (I am a physics student, however, and we've studied light and sight).

Our eyes try to produce a sharp image on the retina.
It does this by focusing light mainly via the cornea, which is situated in front of the iris (it is the curvy outside bit of our eye in front of the colored place, or iris)
The cornea is able to focus this light because of its distinct curvature.
Myopia, which is most likely the condition you have (also known as short-sightedness--the incapacity so see clearly far away) is caused by the excess curvature of the cornea. The excess curvature causes light to focus at a non-ideal place in your eye, producing a blurry image onto the retina.

An injury like yours should not have been able to cause the excess curvature of the cornea. also, you were injured below the retina, so your cornea would not have been directly affected by the incident.

You also mentioned that you could initially see clearly after the incident. This would indicate that your cornea was unscathed from the incident.

Myopia happens most often to people under a period of growth, as the growth may cause the cornea to grow out of proportion in a way that is excessively curved. You mentioned that you began to have trouble seeing afar in high school. Puberty may be the reason. (I became short-sighted in high school, so did many people I knew)

I think that you would've been shortsighted regardless of whether the accident occurred.

If both your eyes cannot see clearly from far away, then my theory is most likely correct.
If only your injured eye cannot see distant objects clearly, then without a doubt, the accident would've been the cause of the seeing defect.

Nevertheless, even if the injury is the cause of your seeing defect today, it would've been unlikely that thorough checking and medical aid would have made a difference to your condition today.
