眼科檢查:

5個重要的理由

Eye Exams: 5 Reasons They Are Important

Jan 21, 2019

年度眼科檢查,不只是檢查您的視力或確保您的視力不模糊。

以下是眼科檢查很重要的五個原因 ........

為什麼你應該每年進行一次眼科檢查來保護你的眼睛健康。

1.眼科檢查幫助孩子在學校取得成功

父母們 , 您是否知道兒童在課堂內外學習時,有80%的時間需要良好的視力嗎? 這是真的 ... 這統計數據已經存在很久,還有向上修正的空間,現今社會的孩子們對著屏幕時間越來越多。每年一次的眼科檢查 ,可確保您的孩子在課堂上及各體育項目取得成功。

2. 近視正在成為一種流行病

 

現今患有近視的兒童大幅上升,為什麼這是一個大問題?

在發育期間如幼童患有近視,而沒有及時發現,近視會有增加及惡化的可能性。

這使他們在成長後增加患嚴重眼疾的風險: 包括白內障、青光眼和視網膜脫落等。

定期眼科檢查是評估孩子近視風險的最佳方法。 在早期,可以採取近視控制措施來減緩近視的進展,並降低孩子長大後患有嚴重眼疾的風險。

3.視力普查不能代替眼科檢查 

通常父母會因為孩子通過了一般的學校視力普查,而認為他們的視力沒有問題。

同樣地有些成年人通過駕駛部門的視力篩查也會認為自己視力正常。

這些假設都不一定正確。

視力篩查的檢驗比較簡單有些時候未必可以全面知道眼睛出了問題,

這樣或會錯過治療的黃金期。 

驗光師或眼科醫生能透過進行全面眼科檢查給予適切的眼睛護理同時亦能及早發現眼疾,例如有些致盲眼疾包括青光眼、眼癌並沒有早期症狀。

4.青光眼 

 

我已經兩次提到青光眼。所以讓我們深入探討一下...... 在所有嚴重的眼疾中,青光眼可能是最偷偷摸摸的。

青光眼可導致視力永久喪失,如患者沒有定期眼科檢查,

他們不容易察覺到任何視覺問題。因為青光眼早期,大多數沒有明顯的症狀 ,

直至永久喪失部份視力。

如沒有及時使用藥物治療和/或手術,青光眼可導致失明。 只有定期眼科檢查才能及早發現高眼壓和青光眼的其他症狀。

5. 每年一次的眼科檢查可以發現其他嚴重的健康問題

許多人初期是透過眼科例行檢查發現自己身體出現問題,如糖尿病,高血壓,高膽固醇甚至癌症。所以我們的眼睛被稱為“靈魂之窗”。

在全面的眼科檢查中,眼科醫生藉著觀察和評估視網膜血管的狀況,可預測身體血管是否出現問題。通過視網膜血液供應和血管的外觀變化可看出糖尿病,高血壓和高膽固醇等病症。 年度眼科檢查對於患有糖尿病或高風險患者(由於肥胖,家族史或其他原因)尤其重要。糖尿病上眼可導致失明,由於毛細血管受到高血糖影響而引起視網膜出現水腫、出血、滲出物、血管增生等情況。全球2.6%的盲症可歸咎於糖尿病。初期糖尿眼沒有明顯的症狀,只有全面的眼科檢查才能發現病變跡象,讓治療得以及早開始,以防止視力下降。

The annual eye exam is not just about checking your vision to make sure your vision is not blurred. Here are five reasons why eye exams are important - why you should have an eye exam every year to protect your health.

1. Eye exams help children succeed in school.

 

OK, this one is for you parents. Did you know that 80 percent of what children are expected to learn in and outside the classroom requires good vision? It's true — and that statistic, which has been around for a long time, probably should be revised upward because of the ever-increasing amount of screen time kids are exposed to these days.

An annual eye exam is the only way to ensure your child is seeing clearly and comfortably to succeed in the classroom. It’s also the only way to know for sure if kids are seeing their best for sports and other activities, too.

2. Myopia is becoming an epidemic.

 

The number of children who are developing myopia(nearsightedness) is growing faster than ever. And more kids are getting nearsighted at a very early age.

Why is this a big concern?

Children who become nearsighted very early in life tend to experience a worsening and progression of nearsightedness that continues throughout childhood — and this puts them at a significantly greater risk of very serious and potentially sight-threatening eye conditions later in life, including cataracts, glaucoma and retinal detachment.

Scheduling annual eye exams is the best way to assess your child's risk of myopia. When detected early, myopia control measures can be taken to slow the progression of myopia and reduce your child’s risk of serious eye problems later in life.

3. Vision screenings are no substitute for an eye exam.

 

Too often, parents are led to believe their child is seeing perfectly well because she passed a school vision screening. Or adults think they see perfectly because they pass a vision screening at the motor vehicle department. Frequently, neither of these assumptions are correct.

Vision screenings are just that — they screen out individuals who have serious (and usually quite obvious) vision problems. Screenings can identify apparent problems a person might have with specific visual tasks, such as seeing a chalkboard clearly in the classroom or recognizing road signs and other objects from behind the wheel.

Only a comprehensive eye exam by an optometrist or ophthalmologist can ensure your vision is as clear and comfortable as possible — and that you're free from potentially serious eye diseases that don’t have obvious early symptoms, including glaucoma and even eye cancer.

4. Glaucoma

 

OK, I've mentioned glaucoma twice already. So let’s dig into it a little deeper...

Of all serious eye diseases, glaucoma is probably the sneakiest. That's because there are no discernible symptoms in most cases of early glaucoma — nothing to alert you that something's going wrong.

People who fail to have routine eye exams and develop glaucoma typically become aware of it only after they’ve sustained permanent vision loss from the disease. And by that time, controlling glaucoma to prevent additional vision loss can be very difficult. Without successful control with medical treatment and/or glaucoma surgery, the disease can lead to blindness.

Early detection of high eye pressure and other risk factors for glaucoma is possible only with routine eye exams. Vision screenings do little to nothing to identify or prevent glaucoma.

5. Annual eye exams can detect other serious health problems

Did you know that many people first learn they have serious health conditions such as diabetes, high blood pressure, high cholesterol and even cancer from — yes, you guessed it — a routine eye exam.

Our eyes have been called "the window to our soul." It turns out, they also are often a very effective window to our overall health.

During a comprehensive eye exam, your eye doctor can observe and evaluate the health and condition of the blood vessels in your retina, which are a good predictor of the health of blood vessels throughout your body. Conditions such as diabetes, hypertension and hypercholesterolemia all are visible by changes in the appearance of the retinal blood supply and blood vessels.

Annual eye exams are especially important for anyone with diabetes or who might be at risk for the disease (due to obesity, family history or other reasons). More than 30 million Americans with diabetes and another 84 million who have prediabetes are at risk for developing diabetic eye disease, the leading cause of blindness among adults. In its early stages, diabetic eye disease has no visible symptoms; only a comprehensive eye exam can detect signs of the disease so treatment can begin soon enough to prevent vision loss.
