Red eye is a often experienced by people and is a common presentation in the emergency department. However, in most cases, the cause is quite trivial and requires primary treatment. If you are worried about red eye and its causes, the following paragraphs will cover all your doubts.
What is red eye?
Red eye is a non-specific term and is also commonly called as bloodshot eyes. Medically, it is called as subconjunctival hemorrhage or hyposphagma. It is bleeding that happens under the conjunctiva. The conjunctiva has may fragile blood vessels that can easily be ruptured. When they rupture, it leads to blood leaking into the space present between the sclera and conjunctiva.
One never realizes they have developed a red eye, till they see themselves in a mirror or someone tells them about their bloodshot eye or eyes. The white of the eye turns bright red due to the bleeding. As the blood cannot get absorbed by the conjunctiva, the redness will persist for about 1 to 2 weeks. However, this is quite a harmless condition.
Symptoms of red eye
The bloodshot eyes are the main and obvious symptom of red eye. There is no discharge or change in vision due to blood eye. One may only feel a bit scratchy on the eye surface.

Diagnosis of red eye
The ophthalmologist will have a look at the eye and diagnose the condition. There are no other tests required to confirm red eye. However, he may ask you to check your blood pressure or carry out a routine blood test to check for any underlying causes.
Treatment of red eye
