During the spring season, people often have hot, itchy eyes, fear of the sun, have to hide in the dark, not much eye mucus but in the form of sticky silk; this is “springtime conjunctivitis”. Spring conjunctivitis is most common in children and adolescents with allergies, especially in boys who are most likely to get it. It often develops in the spring when the weather is warming up, and then fades away in the late fall and winter when it is cold. It is believed that this disease may be related to light, heat, dust, pollen and other stimuli, and is the effect of allergy of the eyes to plant pollen or certain substances in the air in the spring. The main manifestation of springtime keratoconjunctivitis is a congested, hypertrophic conjunctiva on the eyelids, especially on the upper eyelids, where large flattened papillae can appear, making the conjunctival surface look like a cobblestone pavement, and in some patients, the bulbar conjunctiva is congested, with a grayish-yellow gel-like bulge at the corneal junction, and the bulbar conjunctiva can thicken on both sides and appear dirty brownish-yellow. If the disease progresses further, keratitis and corneal ulcers can develop, which can lead to eye pain, photophobia, tearing, and vision loss. What should I do if I have springtime katatonic conjunctivitis? There is no specific cure for keratoconjunctivitis, but children with the disease can avoid external stimuli such as tinted glasses to reduce the stimulation of sunlight, smoke and sand during the onset of the season, and children should be persuaded to avoid playing in dusty, pollen-rich places as much as possible. In terms of treatment: local anti-allergy eye drops, such as sodium cromoglycate, Alamax, Patanlo and other eye drops, any one of which can be used for a long time; in addition, with the point of corticosteroid eye drops, short-term use, such as cortisone, dexamethasone, point Bischoff, Afluron and other eye drops; the above eye drops can eliminate the symptoms and reduce the feeling of eye itching, but can not completely cure. Other places can also take oral antihistamine drugs and calcium; or radiation therapy with beta radiation. However, it should be noted that corticosteroid eye drops should not be used indefinitely because long-term application of such eye drops can cause hormonal glaucoma. It is important to follow medical advice on the use of medication and frequent hospital checkups during the use of medication to prevent drug-induced glaucoma. Many patients with springtime cataract conjunctivitis can gradually heal naturally by the time they reach adulthood, so there is no need to worry too much about this.
