vesicular ophthalmia
Introduction
Introduction to vesicular ophthalmia Follicular ophthalmia is a delayed allergic reaction caused by an epithelial tissue to certain endogenous toxins and is generally considered to be allergic to Mycobacterium tuberculosis proteins. Follicular ophthalmia is a delayed allergic reaction caused by a certain endogenous toxin in the conjunctival epithelial tissue. It is generally considered to be allergic to Mycobacterium tuberculosis protein, and often occurs in female children and adolescents with malnutrition and adenopathy. It is caused by allergies to staphylococcal and intestinal parasitic diseases. There are three main types of vesicular ophthalmia: vesicular conjunctivitis, vesicular keratoconjunctivitis, and vesicular keratitis. Laboratory tests revealed an increase in eosinophils in the secretions. basic knowledge The proportion of sickness: 0.01% Susceptible population: malnutrition and female children and adolescents with adenopathy Mode of infection: non-infectious Complications: keratitis

Prevention
Follicular ophthalmia prevention
It can be treated with corticosteroids and antibiotic eye drops for a short period of time to eliminate inflammation and prevent infection. In addition, correcting partial eclipse, supplementing multivitamins and enhancing physical fitness can have an effect on preventing the occurrence of this disease.
Complication
Follicular ophthalmia complications Complications keratitis
Generally there are no special complications in this disease.
Symptom
Symptoms of vesicular ocular symptoms Common symptoms of tears keratitis X-phenotype herpes Y-phenomenon and rhomboid phenomenon gray-white nodular eyelids
1, self-conscious symptoms, if only the conjunctiva is involved, only mild light, tears, foreign body sensation; if the cornea is involved, there is a high degree of fear of light, tears, eyelids, children often cover their faces with their hands, hiding in the dark, refuse an examination.
2, (1) vesicular conjunctivitis: one or several gray-white nodules appear in the bulbar conjunctiva, about 1 to 3 mm in diameter, composed of serous exudation and lymphocytes, monocytes and macrophages, nodules Peripheral conjunctival hyperemia was present around the body. After a few days, the top of the nodule collapsed and subsided, and healed after 1 to 2 weeks.
(2) Follicular keratoconjunctivitis: The above nodules appear at the junction of the conjunctiva and cornea, slightly higher than the cornea, and the conjunctival vessels of the congested blood vessels fan out, and the corneal margins are uneven after the healing.
(3) vesicular keratitis: herpes is located on the cornea, grayish white, round, clear border, one or several, varying in size, ulceration after ulceration, accompanied by neonatal blood vessels, can leave scar after healing The herpes on the margin often forms a shallow ulcer, recurrent, gradually moving toward the center, and has a bundle of blood vessels following, like a comet, called fascicular keratitis, which has a bundle of thin sputum after healing, but The blood vessels can shrink.
Examine
Examination of blistering ophthalmia
Eye examination. Laboratory tests revealed an increase in eosinophils in the secretions.
Diagnosis
Diagnosis and diagnosis of blistering ophthalmia
Identification with epidemic keratoconjunctivitis, vesicular ophthalmia, pterygium, trachoma, chronic catarrhal conjunctivitis.
