青光眼能预防吗?

Here's why having regular eye exams is one of the best ways to save your eyesight.

When was the last time you had your eyes thoroughly checked? If it's been more than a year or two, you might want to ask your doctor if you're due to be examined for 青光眼, 什么是导致失明的主要原因.          

开角青光眼, 最常见的类型, occurs when pressure builds in your eye, 通常是由于液体过多, 和 causes damage to your optic nerve. Healthy eyes successfully drain 流感id through a spongy tissue near the front of the eye. If you have 青光眼, 流感id builds up because it can't drain quickly enough, like a sink backing up.          

Since 青光眼 doesn't usually cause symptoms in the early stages, many people don't find out they have it until they start losing their eyesight. 虽然你不能预防青光眼, it's a good idea to get tested for it so you can take action to protect your vision before it's too late.

定期眼科检查的重要性

Detecting 青光眼 early gives you the best chance of slowing or preventing vision loss. That's why it's important to have regular comprehensive dilated eye exams. Checking for 青光眼 typically involves:

• measuring your eye pressure, cornea thickness 和 optic nerve
• 评估周边视力
• 检查排水角度
• dilating (widening) your pupil to check for optic nerve damage

Talk with your doctor about how often you should be examined, since this depends in part on age 和 risk factors. You have a higher risk for 青光眼 if you:

• have a family history of the disease
• are older than 60 (though it can occur at any age)
• are African American or Hispanic/Latino 和 are older than 40
• 眼压高
• 是近视眼还是远视眼
• 曾经伤过你的眼睛
• have certain conditions, such as diabetes, high blood pressure, migraines or poor circulation
• have used steroid medications for a long time

如果你有症状, such as blind spots (typically in your peripheral vision) or tunnel vision, call your doctor so you can be examined.    

Also be aware there's a rare type of 青光眼, 称为急性闭角型青光眼, 哪个是医疗紧急情况. Seek care immediately if you have this combination of symptoms:

• 严重的眼痛
• 恶心想吐
• 眼睛发红
• 视力模糊

如何保护视力

青光眼 is often treated with prescription eye drops, which help relieve eye pressure. If eye drops aren't effective, your doctor might recommend laser treatment or surgery.          

In addition to having regular checkups 和 following your doctor's advice, these simple steps may help keep your eyes healthier:

• exercise moderately (but not too intensely)
• wear protective gear when doing home improvements or playing sports
• eat lots of leafy greens, fruits 和 vegetables
• practice good dental hygiene, since gum disease may affect the optic nerve
• elevate your head (about 20 degrees) when you sleep
• discuss your blood pressure medication with your doctor, since low blood pressure may cause vision problems

Although you can't restore eyesight lost due to 青光眼, you may be able to prevent further vision loss by taking good care of your eyes 和 overall health.
