Scleral hyperemia
Introduction
Introduction Scleral congestion refers to the expansion and congestion of the blood vessels of the conjunctiva and sclera in some cases, showing whitening and redness. The most striking symptom of inflamed eyes is redness. For example, acute and chronic conjunctivitis, various keratitis, iridocyclitis, scleritis, glaucoma, and chemical burns of the eyes are the causes of eye congestion.

Clinical examination:
1. Symptoms: Eye redness is the most striking symptom of the eye.
2, such as acute and chronic conjunctivitis, various keratitis, iridocyclitis, scleritis, glaucoma, chemical burns in the eyes are the causes of eye congestion.
3. According to the medical history, clinical manifestations, and patient descriptions, relevant eye examinations are performed to diagnose.
4, pay attention to the diagnosis should pay attention to eyeball congestion is divided into shallow and deep two. The former is bright red, called "eye congestion", the latter is dark red, called "ciliary congestion". Both have a "mixed congestion".
Diagnosis
Differential diagnosis
Differential diagnosis of scleral congestion:
1. Retinal hemorrhage: Retinal hemorrhage is not an independent eye disease, but a common condition in many eye diseases and certain systemic diseases. Clinically, it is generally known as fundus hemorrhage.
Retinal hemorrhage is most common with capillary lesions, mainly capillary endometrial damage, increased permeability, blood exudation; followed by bleeding from the vein, mostly in local or systemic lesions, venous blood flow or retention, blood Viscosity changes, venous thrombosis, inflammation of the vein wall, etc.; bleeding from the arteries is relatively rare, mainly in the vascular wall local atherosclerosis or vascular embolism.
Chinese medicine believes that: blood temperature is blood, blood stasis is blood coagulation, clinical qi deficiency or qi deficiency is delayed, or qi stagnation is blocked, it is easy to cause upper fundus hemorrhage, blood stasis block the eye, often leading to floating clouds in front of the eye, such as The flag is shaken, and the black spot is not seen. Repeated attacks can cause eye pain and so on until blindness.
2, ciliary congestion: congestion of the eye is one of the common signs of 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.
3, conjunctival hyperemia: under normal circumstances, the bulbar blood vessels are squatting, in a "sleeping" state, there is no blood in the blood vessels, so the sclera always looks so white and flawless. When encountering bacteria, viruses, etc., the "sleeping" blood vessels will be immediately "awakened" and then expanded. Then the red blood swarmed from all sides, and the sclera became red. The most striking symptom of inflamed eyes is redness. If you have acute or chronic conjunctivitis, various keratitis, iridocyclitis, scleritis, glaucoma, chemical burns on the eyes, etc., you may have different degrees of eye congestion. 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.
4, spontaneous intrabulbar hemorrhage: common habits in the uveal tumor, more common in 40 to 60 years old, regardless of gender or left and right eyes, can occur in any part of the choroid, but common in the posterior pole of the eye, sometimes Spontaneous intrabulbar hemorrhage occurs, but the overall incidence is one in a million to two.
5, periodic episodes of scleral congestion: periodic episcleitis (periodic episcleitis) also known as transient episcleitis (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.
