Dry Eye

What Is Dry Eye? Symptoms, Causes, Diagnosis, and Treatment | Everyday  Health

Dry eye is a chronic ocular surface disease caused by multiple factors, is caused by the quality, quantity and dynamics of tear abnormalities resulting in tear film instability or ocular surface microenvironmental imbalance, can be accompanied by ocular surface inflammatory reaction, tissue damage and neurological abnormalities, resulting in a variety of eye discomfort symptoms and (or) visual dysfunction. Simply put, the eyes are dry. One of the typical symptoms of dry eyes is redness, increased thickening of conjunctival blood vessels, and red color.

To prevent dry eye, we should try to intervene in various aspects, such as reducing the time spent on cell phones and computers, controlling the distance between eyes, blinking more, using humidifiers in air-conditioned rooms, adjusting sleep, improving sleep quality, reducing late nights, etc.

Glaucoma is a type of pathologically high eye pressure, caused by optic nerve atrophy and visual field loss as a common feature of the disease. Although not all glaucoma patients will eye red, usually acute angle-closure glaucoma sudden increase in intraocular pressure will appear eye red.

The headache is usually in the forehead and temples, and can be either severe migraine or dull pain that may be mild or severe. Severe pain may be accompanied by nausea and vomiting.

Photophobia, afraid to open their eyes in the sunlight, always blinking or even only closed eyes, constantly weeping.

If any of the above conditions occur, that is, a rapid increase in intraocular pressure, prompt medical attention should be sought to avoid irreversible damage to the eye caused by prolonged high intraocular pressure.

Subconjunctival hemorrhage

Subconjunctival hemorrhage is a condition in which the capillaries under the conjunctiva rupture and cause bleeding, and the exuded blood is confined between the conjunctiva and the eyeball, resulting in acute red eye. This is usually a red patch on top of the white eyeball. This condition is not a cause for concern, as the congestion usually resolves on its own within 7-12 days. People often confuse “conjunctival congestion” with “subconjunctival hemorrhage”, because red blood will appear in the eye after a late night or when the eye is overly tired.

Subconjunctival hemorrhage is usually caused by external stimuli, such as forceful eye rubbing, violent coughing, vomiting, and forceful bowel movements. When people cough or have constipation, the abdominal pressure rises due to excessive force, shaking the blood vessels and causing them to rupture. If a patient has recently become fatigued, his or her hormones are likely to change, making the capillaries weaker and more likely to cause subconjunctival hemorrhage. In addition, inflammation of the conjunctiva, arteriosclerosis, hypertension, blood disorders, kidney disease, and certain infectious diseases (such as sepsis and typhoid) can also cause subconjunctival hemorrhage.

Acute conjunctivitis

The most common symptoms of acute conjunctivitis are redness and swelling, tearing, and increased discharge. Many people say, “I haven’t done anything, why do I have acute conjunctivitis? In fact, it “comes” to you when you are not looking for it. Acute conjunctivitis, also known as “pink eye,” is one of the most common infectious eye diseases seen in eye clinics and is highly contagious. Since the incubation period of pink eye is about 24 hours, individual longer will last 3-5 days, and the incubation period will not have too many manifestations, so many patients actually do not realize that they have the disease after the disease.

Special Tips

Once you find red eyes with pain and increased discharge, you should go to the hospital in time to avoid aggravation and spread of the disease due to pink eye.

Chronic conjunctivitis

What Causes Conjunctivitis?

The symptoms of chronic conjunctivitis are not exactly the same as those of acute conjunctivitis, and the manifestations are diverse. The more obvious symptom is the redness of the white part of the eye with blood, and the patient will feel dry, itchy and dry eyes. As a common eye disease in modern life, the incidence of chronic conjunctivitis has been increasing in recent years. The symptoms of chronic conjunctivitis are not serious and do not affect life much. Therefore, many patients often do not pay enough attention to it and easily miss the best time for treatment.

If not treated in time, the condition will continue to worsen, and serious cases can lead to dry eyes, acute and chronic dacryocystitis and other diseases, and eventually seriously affect the patient’s daily life.
