Unbearable itching of eyes
Introduction
Introduction The unbearable itching of the eyes is a prominent symptom of spring catarrhal conjunctivitis. Spring catarrhal conjunctivitis is the most common eye disease, characterized by strong seasonality and often invading the eyes.
Cause
Cause
The cause of the disease may be caused by an allergic reaction to free pollen or other substances in the air. The disease is more common in children and young people, more men, no contagious.

The unbearable itching of the eyes is the most prominent symptom of the disease. At the same time, it can also have a burning sensation. It is even worse when it is hot or after blinking. It has mild photophobia, tearing, and a lot of secretions, but it is characterized by sticky silk. shape.
In the spring, conjunctivitis is clinically divided into sacral conjunctiva, limbal and mixed type.
1, sacral conjunctival type
The lesion is characterized by conjunctival conjunctiva and does not invade the iliac crest. The lower conjunctiva is often invaded or has only mild lesions. At the beginning, the conjunctival hyperemia is very dramatic, followed by a lot of hard and flat nipples in the upper conjunctiva, which vary in size and are covered with sacral conjunctiva. The crack between the nipples is light blue, and the surface of the nipple presents a milky turbidity. There are not many secretions, it is very sticky, and it is drawn into a filament. For smear examination, it can be seen that eosinophils increase. If there is a lesion in the conjunctiva of the lower jaw, the nipple is small and small, and it is not as prominent as the conjunctiva.
2, limbal type
Corresponding to the corneal edge of the cleft palate, or at the upper limbus, one or more yellow-gray gel-like bulging nodules are visible, and the conjunctival hyperemia is corresponding. These gels can be joined to each other, even completely around the limbus. The bulbar conjunctiva is often stained brown. Fine vasospasm and superficial epithelial keratitis are common in both the conjunctival and limbal types.
3, mixed type
If the above two types exist at the same time, they are mixed.
Diagnosis
Differential diagnosis
It should be differentiated from general eye itching: eye itch is more common in ocular inflammatory lesions such as conjunctivitis, blepharitis, dry eye, allergies or contact dermatitis.
If the eye itching is not on the eyeball, but in the eyelids and corners of the eye, and there is no obvious secretion, then you may have blepharitis.
Another common eye disease that can cause itchy eyes is dry eye. Dry eye syndrome is an ocular surface lesion caused by insufficient tear secretion or unstable tears. It is related to the long-term use of computers, televisions, and contact lenses. In the early stages of dry eye, most dry eye syndromes can be alleviated through the use of appropriate rest and artificial tears. However, dry eye syndrome, which has not been effectively treated for a long time, may reduce the number of functional cells on the ocular surface or decrease the activity, eventually further aggravating dry eye syndrome and making it more difficult to treat.
If you have symptoms of itchy eyes, it is best to see a doctor as soon as possible. If you take some inappropriate methods, it will delay the treatment of the disease and cause unnecessary trouble to your life.
