What is the cause of eye congestion? There are these reasons

There are physiological and pathological causes for fundus congestion, the most common of which are conjunctivitis, keratitis, glaucoma, and scleritis. If it is caused by disease, it must be diagnosed and treated in time. Pay more attention to protecting your eyes in daily life, and you can use some appropriate eye drops.

1. Causes of eye congestion:

It turns out that under normal circumstances, the blood vessels of the conjunctiva are deflated and in a "sleeping" state, and no blood flows through the blood vessels, so the sclera always appears so white and flawless. When invaded by bacteria, viruses, etc., the "sleeping" blood vessels will be immediately "woken up" and then expand. Then red blood rushed in from all directions, and the sclera turned red. The most obvious symptom of inflamed eyes is red eyes. Acute and chronic conjunctivitis, various keratitis, iridocyclitis, scleritis, glaucoma, and chemical burns to the eyes can all cause eye congestion. There are two types of eye congestion: superficial and deep. The former is bright red and is called "eye congestion"; the latter is dark red and is called "ciliary congestion". The combination of both is called "mixed congestion".

2. Examination and diagnosis of ocular congestion:

(1) Acute conjunctivitis:

Cause: It is a common epidemic eye disease caused by bacterial and viral infection and is highly contagious. Symptoms: Acute onset, both eyes affected simultaneously or successively, the affected eye has stinging, itching, foreign body sensation, severe cases have photophobia and burning sensation, vision is generally not affected.

Symptoms: Red and swollen eyelids, conjunctival congestion, and secretions that are mostly bacterial, mucous or purulent. When I woke up in the morning, my eyes were closed with secretions. The secretions of viral infections are mostly watery and may be accompanied by corneal lesions, enlargement and tenderness of the preauricular and submandibular lymph nodes.

Treatment mechanism: This disease is highly contagious and should be prevented and isolated. Towels and handkerchiefs should not be used by each other, and washbasins should be rinsed and disinfected after use. Keep the eyes clean. When there is a lot of secretion, rinse with clean water and apply antibiotics and antiviral drugs locally. If there are systemic symptoms such as fever and headache, medical treatment should be combined.

(2) Acute iridocyclitis:

Cause: The causes of iris and ciliary body diseases are very complex, and most of them are unknown. They may be related to autoimmune diseases such as rheumatism, tuberculosis, syphilis, viral infections, etc.

Symptoms: ciliary congestion or mixed congestion, precipitates behind the cornea (abbreviated as KP), turbid aqueous humor, swollen iris, constricted or irregular pupil, slow light reflex, posterior adhesion of part of the iris and lens; intraocular pressure is generally normal, but sometimes it may increase or decrease, decreased vision is accompanied by obvious photophobia, tearing, pain, and the pain may radiate to the eyebrow arch, temporal and forehead.

Treatment mechanism: Actively find the cause of the disease and treat it. Use 1% atropine eye drops topically to dilate the pupil, apply hot compresses, or use hormone eye drops or subconjunctival injections. Severe patients require systemic intravenous or oral hormones and anti-inflammatory drugs.
