ciliary congestion
Introduction
Introduction Congestion and redness of the eye is one of the common signs in ophthalmology patients. It is often said that red eye is a general concept, which refers to conjunctival hyperemia and ciliary congestion. Conjunctival hyperemia is limited to conjunctival disease or related superficial stimulation, while ciliary congestion includes diseases of the cornea, sclera, and anterior pigmentation, often with certain severity.
Cause
Cause
Ciliary congestion is deep congestion, caused by inflammation or irritation of the cornea, iris, ciliary body, etc.
Ciliary congestion is deep hyperemia, which is the reaction of the ciliary vascular system Cilary (anterior ciliary system, posterior arterial system), usually the inflammatory reaction of the cornea, iris ciliary body, choroid, sclera and so on. It is manifested in the cornea (next to the black eyeball). It is deeper and has a brush-like shape. It is short and straight, and the pressure is not retreating. The color is dark. Conyun, the conjunctival vasculature, is completely two systems with different performances, derived from different diseases, and is also the theoretical basis for clinical identification of diseases.

Corneal examination
Diseases characterized by ciliary congestion are:
1 keratitis;
2 scleritis and superficial scleritis;
3 uveitis, including iritis, ciliary body inflammation, iridocyclitis and choroiditis;
4 glaucoma, with acute angle-closure glaucoma as obvious, even showing mixed hyperemia, followed by chronic angle-closure glaucoma, glaucoma ciliary body syndrome, etc.;
5 eyeball injury, regardless of eye contusion or trauma, can show ciliary congestion, severe cases can be mixed hyperemia, trauma can be used as a reference.
Diagnosis
Differential diagnosis
Scleral congestion: refers to the expansion and congestion of the blood vessels of the conjunctiva and sclera in some cases, showing whitening and redness. Periodic episodes of scleral congestion: Periodic episcleitis (periodic episcleitis) is also known as transient episcleritis. Most occur in women's menstrual period. The scleral surface and the bulbar conjunctiva of the lesion were diffusely congested and edematous, and were purple-red. It is a periodic episode, each episode is short-lived, and the constant is small or several days. Recurrence is not limited to one eye or the same site. The anterior sclera area usually occurs, and no localized nodules are formed.
Eye congestion: The general concept is that the eyes are red. When the blood vessels of the bulbar conjunctiva and sclera are dilated and congested under certain conditions, when they are congested or hemorrhage, they may appear white and red. Because the blood supply of different parts of the eye is different, the appearance of the eye congestion is different, and the lesions are not the same. Therefore, eye congestion is a common symptom common to many eye diseases. Conjunctival hyperemia: eyeball congestion is divided into two types: shallow and deep. The former is bright red, called "conjunctival hyperemia"; the latter is dark red, called "ciliary congestion". Both have a "mixed congestion". The different congestion in these cases is very meaningful in the examination and diagnosis of doctors. It is also an important basis for judging the severity of eye diseases, but it is difficult for ordinary laymen to distinguish clearly. Some people think that the more the eyes are red, the more serious the condition. Some people don't care too much about the redness. actually not. For example, acute conjunctivitis, acute onset, and heavy congestion, but it is not a serious illness, if there is no special situation, it will not cause major problems, it is easier to cure. However, for chronic iridocyclitis, scleritis, glaucoma and other diseases, the symptoms of congestion are not obvious, but it is a serious eye disease that cannot be ignored. Most of the internal eye diseases are not congested on the outside, but they may cause blindness. So don't judge the severity of eye disease from the weight of red eye or the congestion of eyes.
