one's eyes become bloodshot
Release time : 06/02/2025 09:30:02
The baby has been rubbing their eyes before bedtime, and I've noticed that the skin around the corner of their eye is red. After they wake up, it disappears. Just tonight, I noticed a lot of red blood vessels in the white part of the right eye, with congestion. Is this a sign of red eye disease? Or could it be due to a collision? Should we go to the hospital or just take care of it ourselves? What causes conjunctival congestion? The general concept refers to the redness of the eyeball.
When the blood vessels in the bulbar conjunctiva and sclera tissues expand, congest, swell or bleed, it can manifest as eye whiteness.
Due to the different blood supply sources for various parts of the eye, their congestion manifestations differ, and the affected areas also vary.
Therefore, conjunctival congestion is a common symptom of many eye diseases.
The eyeball congestion can be divided into superficial and deep layers.
The former appears bright red and is called "conjunctival congestion".
The latter is dark red and is called "ciliary congestion."
Those with both features are referred to as "mixed congestion."
These conditions, different degrees of congestion, are an important basis for assessing the severity of eye diseases. However, laypeople often struggle to discern them clearly.
The cause of the eye redness was confirmed by the doctor's thorough examination, and it was confirmed that Mi Le had contracted keratitis.
Mei Le was puzzled, how could she have developed keratitis? The doctor told her that there are many causes of conjunctival congestion, and different manifestations represent different etiologies.
1. Acute conjunctivitis - This is a common epidemic eye disease caused by bacterial and viral infections, with strong infectivity.
Symptoms: The onset is swift, with both eyes developing symptoms simultaneously or sequentially. The affected eye experiences a sensation of itching, irritation, or foreign body feeling, with more severe cases experiencing a sense of light sensitivity and burning sensation. Generally, vision is not affected.
Eyelid swelling, conjunctival congestion, and exudate mostly bacterial, mucoid or purulent.
Upon waking, my eyes are sealed by secretions.
The secretions of viral infections are mostly watery and may be accompanied by corneal lesions, swelling and tenderness of preauricular and submandibular lymph nodes.
Treatment and Precautions: This condition is highly contagious, and it is necessary to prevent isolation. Do not use the same towel or handkerchief for different people; after using a basin, rinse it thoroughly and disinfect it.
Maintain eye hygiene; when there is excessive secretion, rinse with water. Apply antibiotics or antiviral agents topically.
Should there be symptoms such as fever and headache, internal medicine treatment should be combined.
Eye congestion is a common symptom in many eye diseases. 2. Acute Iridociliary Pulmonitis - The pathogenesis of the iris and ciliary body is complex, with most causes unknown. It may be related to autoimmune diseases such as rheumatism, tuberculosis, syphilis, and viral infections. Symptoms: Conjunctival hemorrhage or mixed congestion, corneal posterior deposits (KP), cloudy anterior chamber, dilated or irregular pupil, delayed light reflex, and posterior lens-ciliary body adhesion.
Eye pressure is generally normal but may increase or decrease at times.
Visual impairment accompanied by obvious photophobia, tearing, and pain, which can radiate to the brow arch, temporal region, and forehead.
Treatment and precautions: Actively search for the cause and treat it.
Local application of 1% atropine eye drops for dilation, hot compresses, steroid eye drops, or subconjunctival injections may be required. In severe cases, systemic intravenous injections or oral administration of corticosteroids and anti-inflammatory drugs are necessary.
3. Corneal Ulcers - Most cases of keratitis are caused by foreign infections.
Minor corneal injuries often serve as a precipitating factor for infection, with common pathogens including bacteria, fungi, and viruses.
Additionally, corneal immunodeficiency or malnutrition can cause keratitis.
Symptoms include pain in the affected eye, foreign body sensation, blepharospasm, photophobia, tearing, and sudden vision loss.
The symptoms of keratitis caused by different etiologies share common features, but the basic signs include: ptosis and conjunctival swelling, conjunctival congestion with significant redness, mixed congestion of the bulbar conjunctiva accompanied by edema, corneal opacification or ulceration formation, presence of deposits in the anterior chamber, and accumulation of purulent material.
Treatment and Precautions: To treat keratitis, the first step is to eliminate the cause.
The majority of keratitis is caused by infection, so appropriate antibiotics and antiviral drugs are important.
We can diagnose various types of conjunctivitis by observing the clinical characteristics, exudates or ulcer tissue scrapings stained with a microscope and cultured for bacteria.
Drug sensitivity tests and other procedures are used to accurately diagnose the cause of illness.
If it is bacterial keratitis, broad-spectrum antibiotics can be used; If it is caused by Pseudomonas aeruginosa, tobramycin, polymyxin, and colistin can be added.
Fungal keratitis can be treated with antifungal drugs such as amphotericin B and aureomycin.
Viral keratitis can be treated with acyclovir, viral acne, etc. The administration route can be local drip or subconjunctival injection.
In addition, 1% atropine eye drops can be used to dilate the pupils, paralyze the ciliary muscle to relieve pain, and prevent posterior adhesion of the iris.
Local heat therapy, using eye pads for bandaging, can be beneficial in relieving pain, promoting local blood circulation, and facilitating the resolution of inflammation and the healing of ulcers.
In cases where the etiology is not immediately clear, broad-spectrum antibiotics or a combination of multiple antibiotics can be employed for treatment.
4. Acute Posterior Syndrome Glaucoma - Its etiology is relatively complex, with women being two to four times more likely than men, and it commonly occurs in middle-aged and older women, presenting as a bilateral condition and related to genetic factors.
The primary cause is due to the closure of the pupil angle, obstructing the pathway for the outflow of aqueous humor, leading to elevated intraocular pressure.
Symptoms: Elevated eyelid and conjunctival swelling, marked congestion of the sclera, cloudy corneal edema, extremely shallow anterior chamber, engorged iris, dilated pupil, absent light reflex, and very high intraocular pressure, which can exceed 60 mmHg.
Vision suddenly declines, severe eye pain, unilateral headache, and nausea or vomiting (easily misdiagnosed as gastrointestinal disorders).
Treatment and Precautions: Acute angle-closure glaucoma is a rapidly developing condition with severe symptoms that can lead to blindness within minutes. Timely intervention is crucial, aiming to control the intraocular pressure within 24 to 48 hours.
In principle, medication should be used to control intraocular pressure and surgery should be performed as soon as possible.
Medications to lower intraocular pressure mainly include 20% mannitol solution, 50% glycerin, and acetazolamide tablets.
5. Subconjunctival Hemorrhage: It is mostly caused by hypertension, arteriosclerosis, impaired coagulation function, local inflammatory conditions, or increased fragility of the blood vessels, and it occurs after vigorous straining or trauma.
The patient generally has no discomfort, with occasional mild soreness that is often discovered incidentally or by others.
Spots or patches of bleeding are visible on the sclera. The pressure does not cause color to fade, fresh bleeds are bright red, and older ones are dark red.
To treat keratitis, the primary step is to eliminate the cause of the disease. Precautions:
The symptoms of eye congestion, and upon returning home, Mi Le hastily removed her contact lenses and put on her spectacles to look at herself in the mirror. She notices that the white part of her eyes is covered with a large number of small, long, and short red strands, which are quite extensive.
Upon checking online, I found out that this is due to eye redness.
Mila was suddenly puzzled: what's this about red eyes? Simply put, it refers to the appearance of redness in the white part of the eye.
The medical causes leading to eye redness include dilation, congestion, engorgement, or bleeding of the blood vessels in the sclera and cornea tissues under certain circumstances.
Due to the different blood supply sources of various parts of the eye, the appearance of congestion varies and the sites of the pathological changes also differ.
Therefore, eye congestion is a common symptom shared by many eye diseases.
Chronic conjunctivitis, characterized by the conjunctival redness, represents primary or secondary diseases of the conjunctive or its associated structures.
Conjunctival congestion represents a disease of the eye itself, such as corneal ulcers, scleritis, uveitis, congestive glaucoma, etc.
If the blood vessels themselves are diseased or damaged and rupture, then bleeding can accumulate beneath the conjunctiva, known as subconjunctival hemorrhage, which is also a form of conjunctival congestion.
From the perspective of patients, eye inflammation generally results in certain clear symptoms in the eyes.
In the early stages, patients may only experience a sensation of itchy eyes and have a strong urge to rub them.
However, as inflammation intensifies, the patient's eyes may exhibit prominent symptoms such as redness and congestion, possibly accompanied by pain and other discomfort.
What to do if the eyes are red? Doctor Mi Le told her that her keratitis is not serious. Generally speaking, there are several basic treatment measures for this kind of inflammation-induced eye redness.
1. For those with bacterial infection factors, antibiotic eye drops can be used, three to four times a day.
For non-infectious factors, it is not appropriate to misuse or routinely use as a placebo.
2. The use of corticosteroid eye drops can be considered as a pilot treatment, but it should not be prolonged and monitoring of intraocular pressure is essential.
3. Pearl Eyesight Liquid, three to four times daily.
4. If oral administration of decoctions is unsustainable, one may consider taking yin-nourishing and fire-lowering pills such as Yin Qi Sheng Huo Wan, Zhi Bai Di Huang Wan, or Yin Qiao Jie Du Wan.
Of course, the most important thing is to treat the specific cause in a targeted manner, which can effectively control and cure the condition.
How to prevent eye redness? Eyes are the window of the soul, but eye redness not only affects appearance, but also causes inconvenience for daily use.
So, how do we prevent eye redness? Let's learn more about it together.
1. Blinking 300 times a day.
20-40 years old normal people blink 20 times a minute. When you stare at the moving fast computer screen, your blinking rate will decrease to 4-5 times a minute and cause severe lack of tear secretion, which results in dryness and irritation of eyes.
Consequently, deliberate blinking is highly effective in protecting the eyes.
Generally speaking, it is appropriate to blink 300 times every day. This not only helps promote tear secretion and alleviate symptoms of dryness and astringency but also cleanses the eyes and provides gentle massage for the eyes, thereby relieving eye fatigue.
2. The method of hot compress often uses hot water, hot towels or steam to soak the eyes, which can promote blood circulation in the eyes and reduce eye fatigue.
Massage Method: Close your eyes, gently press and rub the eyeballs with the tips of your index, middle, and ring fingers.
Do not hold it for too long or press hard, stop in 20 seconds.
4. When you look at something for a long time, try to look away and gaze at the distant scenery. If it's green or seascapes, even better. Look away from the thing for 10 to 15 minutes, and your eyes will feel more comfortable.
5. Intake of sufficient Vitamin C can weaken the damage caused by light and oxygen on the lens, and have a function to prevent eye congestion.
