What are the symptoms of allergic conjunctivitis in children?

Eyes are a very important organ in our human body, but they are also a very fragile organ. There are many types of eye diseases, but allergic conjunctivitis is the most common. In recent years, due to the deterioration of the living environment, the incidence of this disease has been on the rise, especially among children, the increasing trend is more serious. So what are the symptoms of allergic conjunctivitis in children?

Allergic conjunctivitis is an allergic reaction of the conjunctiva caused by contact with allergic antigens, which is mainly a type I allergic reaction mediated by IgE. Anyone who is genetically or physically susceptible to specific antigens may develop immediate or delayed allergic conjunctivitis when exposed to such antigens, often accompanied by allergic rhinitis. Vernal keratoconjunctivitis is more common in children and often occurs or worsens in spring and summer. Atopic conjunctivitis is more common in middle-aged men, and often has a history of mild allergies in the early stages. Some cases of vernal keratoconjunctivitis and atopic conjunctivitis can cause serious corneal complications and even endanger vision. Like all allergic diseases, allergic conjunctivitis occurs when the conjunctival mucosa of the eye comes into contact with allergens, resulting in conjunctival inflammation.

Seasonal allergic conjunctivitis is most common in young and middle-aged people. It has a rapid onset and occurs when exposed to allergens. Symptoms are relieved when away from allergens. The main difference between perennial and seasonal conjunctivitis is that allergic symptoms exist all year round. Contact allergic conjunctivitis has a clear history of exposure, such as exposure to drugs or cosmetics.

Giant papillary conjunctivitis is often associated with a history of contact lens (corneal contact lens) wear. Vernal keratoconjunctivitis is more common in children and often occurs or worsens in spring and summer. Atopic conjunctivitis is more common in middle-aged men, and often has a history of mild allergies in the early stages. Some cases of vernal keratoconjunctivitis and atopic conjunctivitis can cause serious corneal complications and even endanger vision.

Typical symptoms: Skin itching (80%), conjunctival congestion (75%), conjunctival edema and corneal ulcers (75%), unbearable itching in both eyes (65%). Most patients with allergic conjunctivitis experience unbearable itching. In addition, there are symptoms such as conjunctival congestion and edema, mucous secretions, and redness and swelling of the eyelid skin. The closer to the corner of the eye, the more serious the condition. Patients generally do not have eye pain, no obvious visual impairment, and their pupils are normal. The symptoms will improve or worsen with the change of seasons and recur repeatedly, which means that in addition to the patient's allergic constitution, climate change and the patient's activities are important factors in the onset of the disease. Generally speaking, the symptoms will worsen on warm and dry days when flowers are blooming. In addition to eye discomfort, some patients may also have nasal allergy symptoms. This condition is also clinically called allergic rhinitis conjunctivitis.

From the above introduction, we know the symptoms of allergic conjunctivitis in children. Therefore, once a child suffers from allergic conjunctivitis, it is necessary to take the child to the ophthalmology department of the hospital for examination and treatment in time, and take medication under the doctor's instructions. Parents should also note that allergic conjunctivitis has certain allergens, so in seasons prone to allergies, parents should try to keep their children out as little as possible to avoid allergies.
