Conjunctival congestion

Under normal circumstances, the blood vessels of the bulbar conjunctiva are cramped and in a "sleepy" state. There is no blood in the blood vessels, so the sclera always looks so white and flawless. When encountering invasion by bacteria, viruses, etc., the "sleeping" blood vessels are immediately "woken up" and then dilated. The red blood swarmed from all directions, and the sclera became red. The most striking symptom of an inflamed eye is redness. If you have acute or chronic conjunctivitis, various keratitis, iridocyclitis, scleritis, glaucoma, or chemical burns on the eyes, you can have eye hyperemia in varying degrees. Eye congestion is divided into two types: superficial and deep. The former is bright red and is called "conjunctival congestion"; the latter is dark red and is called "ciliary congestion". Both are called "mixed congestion". These different types of congestion are very meaningful in the doctor's examination and diagnosis, and also one of the important basis for judging the severity of the eye disease, but it is difficult for ordinary laymen to distinguish clearly. Some people think that the more red your eyes are, the worse your condition will be. Some people don't care much about jealousy. actually not. For example, acute conjunctivitis has an acute onset and heavy congestion, but it is not a major illness. If there is no special condition, it generally does not cause major problems and is relatively easy to cure. However, for chronic iridocyclitis, scleritis, and glaucoma, the symptoms of congestion are not obvious, but they are serious eye diseases that cannot be ignored. Most internal eye diseases are not congested on the outside but can cause blindness. Therefore, do not judge the severity of eye disease solely by the severity of red eyes, or the presence or absence of eye congestion.
