· 发病原因
· 眼结膜下出血系由于结膜小血管破裂。见于外伤和眼部手术后,更为常见的是自发性出血。见于严重急性结膜炎的结膜下出血,可能是由微小血管栓塞所致。自发出血多见于老年人、背驮重物、恶心呕吐、剧烈咳嗽、喷嚏、便秘等诱因,亦可致小血管: 破裂出血。坏血症、各种血液病、紫癜、动脉硬化、糖尿病、高血压以及疟疾等高热性传染病亦可发生。
· 当颅骨底部骨折后,出血沿眶底向前扩延到下穹隆部、下方球结膜及下睑皮下,出血量一般较大。蝶骨骨折晚期出血出现在颞侧较其他部位多。一般这种出血多发生在头颅外伤后,是颅底骨折重要体征之一。
· 严重眼球钝挫伤,结膜下出血量大,呈黑红色者应注意排除巩膜破裂之可能。结膜下出血呈鲜纡色。平坦、境界清楚、点或片状,出血量多时呈黑红色。除急性结膜炎引起的出血外,不伴炎症体征。出血逐渐吸收,颜色由红色变为棕、黄色雨消失,不留痕迹。局部无需治疗,通常1~3周可吸收消退。反复出血者应查找致病原因,予以治疗。
· 发病
· 1、高血压∶好发于老年人,若合并“结膜下出血”,应定期测量血压,其他如糖尿病或心血管疾病患者也易引发,需加以留意。
· 2、急性结膜炎∶由70型肠病毒所引起,具高度传染性,若合并结膜水肿,眼皮肿胀,分泌物增加时需高度怀疑。
· 3、局部轻微受伤引起∶例如因过敏性结膜炎或干眼症用力揉擦眼睛所造成;需闭气用力的便秘解便、生产、搬重物等;以及伤风感冒、被辛辣食物呛到而导致咳嗽的情况。

Subconjunctival hemorrhage (broken blood vessel in eye ...
https://www.mayoclinic.org/diseases-conditions/sub...
A subconjunctival hemorrhage (sub-kun-JUNK-tih-vul HEM-uh-ruj) occurs when a tiny blood vessel breaks just underneath the clear surface of your eye (conjunctiva). In many ways, it's just like having a bruise on your skin. The conjunctiva can't absorb blood very quickly, so the blood gets trapped. You may not even realize you have a subconjunctival hemorrhage until you look in the mirror and notice that the white paart of your eye is bright red.
A subconjunctival hemorrhage often occurs without any obvious harm to
your eye. Even a strong sneeze or cough can cause a blood vessel to
break in the eye. You don't need to treat it. A subconjunctival
hemorrhage may look alarming, but it's usually a harmless condition
that disappears within two weeks or so.

Symptoms
The most obvious sign of a subconjunctival hemorrhage
is a bright red patch on the white (sclera) of your eye.
Despite its bloody appearance, a subconjunctival hemorrhage looks worse than it is and should cause no change in your vision, discharge or pain. Your only discomfort may be a scratchy feeling on the surface of the eye.
When to see a doctor
If you have recurrent subconjunctival
hemorrhages or other bleeding, talk to your doctor.结膜下再次或反复出血或其他部位同时出血需要咨询专业的医生
Causes
The cause of a subconjunctival hemorrhage isn't always
known. The following actions may cause a small blood vessel to rupture
in your eye:
· Violent coughing
· Powerful sneezing
· Straining
· Vomiting
In some cases, a subconjunctival hemorrhage may result from an eye injury, including:
· Roughly rubbing your eye
· Trauma, such as a foreign object injuring your eye
Risk factors
Risk factors for a subconjunctival hemorrhage include:
· Diabetes
· High blood pressure (hypertension)
· Certain blood-thinning medications, such as warfarin (Coumadin, Jantoven) and aspirin
· Blood-clotting disorders
Complications
Health complications from a subconjunctival
hemorrhage are rare. If your condition is due to trauma, your doctor
may evaluate your eye to ensure you don't have other eye complications
or injury.
Prevention
If the bleeding on the surface of your eye has a
clearly identifiable cause, such as a bleeding disorder or
blood-thinning medication, ask your doctor if you can take any steps
to reduce the risk of a subconjunctival hemorrhage.
If you need to rub your eyes, rub them gently. Rubbing too hard can cause minor trauma to your eyes, which may lead to a subconjunctival hemorrhage.
