What's going on with bloodshot whites of the eyes

If you find that the whites of your eyes are bloodshot, you should pay attention to the causes. If it is an eye disease such as acute conjunctivitis or keratitis, it will usually show symptoms of bloodshot whites of the eyes, so you need to treat it symptomatically.

(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. If there is a lot of secretion, rinse with clean water and apply antibiotics or antiviral drugs topically. If there are systemic symptoms such as fever and headache, internal medicine 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, deposits behind the cornea (abbreviated as KP), turbid aqueous humor, swollen iris, constricted or irregular pupil, slow light reflex, and 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, and pain, and the pain may radiate to the eyebrow arch, temporal region, and forehead.

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

(3) Keratitis

Cause: Most keratitis is caused by external infection. Minor corneal trauma is often the cause of infection, and common pathogens are bacteria, fungi, viruses, etc. In addition, corneal immune dysfunction or malnutrition can cause keratitis. Physical symptoms: pain in the affected eye, foreign body sensation, blepharospasm, photophobia, tearing, sudden decrease in vision, etc.

Symptoms: Keratitis caused by different causes has its own characteristics, but the basic symptoms are blepharospasm and edema, obvious conjunctival congestion, mixed congestion and edema of the bulbar conjunctiva, corneal opacity or ulceration, visible sediment behind the cornea, and pus in the anterior chamber.

Treatment mechanism: The first step in treating keratitis is to remove the cause. Most keratitis is caused by infection, so it is important to choose appropriate antibiotics and antiviral drugs.
