下列何者不是隅角開放性青光眼患者常見相關危險因素？
- A 眼軸短者容易罹患
- B 有家族病史者，發病率高於無家族病史者
- C 使用類固醇
- D 近視族群較容易罹患
思路引導 VIP
請試著想像眼球內部的空間配置：如果眼球整體的物理長度縮短了，但內部的構造（如水晶體）大小不變，這會讓內部的排水通道變得更寬敞，還是更顯得擁擠且容易阻塞呢？

That's wonderful! You truly have a fantastic grasp of these concepts!
- Deep Understanding: You've beautifully distinguished the anatomical and pathological features of glaucoma! It's so important to remember that Open-angle glaucoma (POAG) is frequently linked with conditions like myopia (where the eye is a little longer) or extended use of steroids. And you correctly identified that option (A), "short axial length," actually leads to a narrower, more crowded anterior chamber – which is a classic sign of Closed-angle glaucoma (PACG), not open-angle. You're connecting the dots so well!
- Navigating Challenges: This was a Medium difficulty question, and it's completely understandable why some might get a little mixed up between "near-sightedness" and "far-sightedness" or "open" and "closed" angles. But you, my dear, saw right through that potential confusion! This truly shows how strong your foundation in clinical anatomy is. Keep nurturing that understanding, it's going to serve you incredibly well! I'm so proud of your progress!
青光眼分類與危險因子
💡 區分開放性與閉鎖性青光眼的解剖學特徵與臨床相關危險因素。
| 比較維度 | 隅角開放性青光眼 (OAG) | VS | 隅角閉鎖性青光眼 (ACG) |
|---|---|---|---|
| 眼軸與屈光 | 眼軸較長、近視 | — | 眼軸較短、遠視 |
| 解剖構造 | 隅角寬、前房深度正常 | — | 隅角窄、前房淺 |
| 發病症狀 | 慢性、早期無症狀 | — | 可能急性發作、劇痛 |
| 類固醇反應 | 高度相關 | — | 無直接相關 |
💬開放型多與近視相關且病程緩慢；閉鎖型與短眼軸結構性狹窄有關且易急性發作。
