這幾種西藥 影響視力，甚至造成失明 ZT

雖然您應該檢查任何新藥物的潛在視覺副作用，但有些人會脫穎而出。這份清單隻提供了一些常見的罪魁禍首。

皮質類固醇：人們服用這些疾病可以治療各種疾病，從哮喘，過敏到關節炎和皮膚病。但無論是乳霜還是藥丸形式，它們都會導致眼睛後部或視網膜腫脹，並可能導致白內障。即使像Flonase這樣的非處方鼻噴霧也存在風險。

抗組胺藥：它們可能對抗過敏，但它們也會引起某些患者患青光眼的風險。有關風險等級特別高的人，請參閱下麵的更多信息。

抗精神病藥：Thorazine和Mellaril等藥物對視網膜有毒。

抗瘧藥：例如，用於治療瘧疾，狼瘡和關節炎的Plaquenil也對視網膜有毒性作用。

其他藥物可能會增加眼科手術的風險和其他條件，如果您有疑慮，請谘詢您的醫生。如果您服用有風險的藥物，請務必定期進行眼科檢查，以確保它們不會損害您的視力。

誰的風險最高？
服用可的鬆等藥物的人可能會出現視覺副作用。

但如果你患有青光眼或糖尿病，你應該特別警惕。有些人的眼睛被配置成具有“窄角”，使他們處於急性青光眼發作的風險中。像Topamax這樣的磺胺類藥物，或像Detrol或Ditropan這樣的某些抗組胺藥或失禁藥物，可以引起角度較小的人患青光眼的急性發作。

糖尿病患者特別容易因可的鬆而出現視力模糊。由於血糖水平過高，眼睛晶狀體內會暫時腫脹，導致視力模糊。由於血糖控製不佳，眼內可能發生結構性損傷，導致嚴重的視力喪失。

Which drugs pose the most concern?

A few stand out, although you should check for potential visual side effects with any new medication. This list offers just a few common culprits.

Corticosteroids: People take these for a range of conditions, from asthma and allergies to arthritis and skin conditions. But whether in cream or pill form, they can cause swelling in the back of the eye or retina and potentially lead to cataracts. Even an over-the-counter nasal spray like Flonase comes with risks.

Antihistamines: They may fight allergies, but they also can raise certain patients’ risk for glaucoma. See more information below for those with particularly high risk levels.

Antipsychotic medications: Drugs such as Thorazine and Mellaril can be toxic to your retina.

Antimalarials: For example, Plaquenil — used to treat malaria, lupus and arthritis — also has toxic effects on the retina.

Other drugs may raise eye surgery risk and other conditions, so talk to your doctor if you have concerns. And if you take a medication that comes with risk, be sure to have regular eye exams to make sure they don’t damage your vision.

Who has the highest risk?

Anyone taking medications such as cortisone and others listed above may experience visual side effects.

But if you have glaucoma or diabetes, you should be especially vigilant. Some people’s eyes are configured to have a “narrow angle” that puts them at risk for an acute onset of glaucoma. Sulfa drugs like Topamax, or certain antihistamines or incontinence medications like Detrol or Ditropan, can trigger an acute attack of glaucoma in someone with a narrow angle.

People with diabetes are especially prone to developing blurred eyesight from cortisones. With high blood sugar levels, there is temporary swelling within the lens of the eye, resulting in blurred vision. With poor control of blood sugar, structural damage can occur within the eye that can cause severe vision loss.
