Red eyes



Redness of the eyes is a manifestation of 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, and it is also an important basis for judging the severity of eye diseases. The causes of red eyes are varied. Since the bulbar conjunctiva is exposed to the front of the eyeball, it is vulnerable to trauma and microbial attack. The most common cause of eye redness is inflammation of the eye.



Causes of redness of the eyes:

Redness of the eyes refers to white eyes. The so-called white eyeballs, redness, that is, the conjunctiva that covers the front of the eyeball is red. It may be caused by local inflammatory stimuli, vasodilatation, congestion, or conjunctiva caused by non-inflammatory factors. Small blood vessels rupture, that is, subconjunctival hemorrhage. Under normal circumstances, the blood vessels of the bulbar conjunctiva are squatting, in a "sleeping" state, and 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.

Eye redness check diagnosis:

1, the incubation period of 1-3 days, acute onset, two eyes at the same time or 1-2 days after the onset of disease. The patient feels itchy and foreign body sensation, and then burns, photophobia, and eyelids are difficult to open due to swelling. Sometimes, due to excessive secretion, it appears, and after the secretion is removed, vision is immediately restored.

2, the secretion is mucus or mucus purulent, can adhere to the eye and eyelashes, fibrin in the secret secretions into the milk, attached to the surface of the conjunctiva of the eye mask, it is easy to use the tweezers to peel off, leaving a slight bleeding No, but no tissue defects.

3, eye conjunctival hyperemia, with sputum conjunctiva and sputum conjunctiva most obvious, there are symptoms of fashion red eye disease 4, 3-4 days after the onset of disease reached a climax, later gradually reduced, about two weeks to heal, can be complicated by marginal corneal infiltration or ulceration.


Differential diagnosis

Symptoms of redness and confusion of the eyes:

(1) Acute conjunctivitis:

Cause: It is a common epidemic eye caused by bacterial and viral infections and is highly contagious. The onset is urgent, both eyes have the same or successive disease, the eyes have tingling, itching, foreign body sensation, the heavy ones have photophobia and burning sensation, and the visual acuity is generally unaffected.

Signs: eyelid swelling, conjunctival congestion, secretions are mostly bacterial, mucinous or purulent. In the morning, the eyes are closed by secretions. The secretion of viral infection is mostly watery, and may be accompanied by corneal lesions, swelling of the ear and submandibular lymph nodes and tenderness.

Treatment: The disease is highly contagious. It should be prevented from isolation. Towels and handkerchiefs should not be used with each other. The washbasin should be rinsed and disinfected after use. Keep eye clean, rinse with plenty of water for a long time, and use antibiotics and antiviral drugs locally. If there are systemic symptoms such as fever and headache, it should be combined with medical treatment.

(2) Acute iridocyclitis:

Causes: The pathogenesis of the iris ciliary body is very complicated, most of the causes are unknown, and may be related to autoimmune diseases such as rheumatism and tuberculosis, syphilis, and viral infections. Vision loss is accompanied by significant photophobia, tearing, and pain, which can be radiated to the eyebrows, ankles, and forehead.

Signs: ocular ciliary congestion or mixed congestion, deposits behind the cornea (kp), aqueous humor, iris swelling, dilated or irregular pupils, slow light reflection, part of the iris and lens after adhesion, normal intraocular pressure But sometimes it will increase or decrease.

Treatment: Actively search for the cause and treat the cause. Topical 1% atropine eye water dilatation, hot compress, hormone eye drops or subconjunctival injection, severe patients need systemic intravenous or oral hormones and taking indomethacin drugs.
