F. conjunctivitis is a purulent inflammation of the mucous membrane of the eyeball, usually severe with suppuration of the hair follicles. Adults and children get sick. The causative agents of the disease are staphylococcus, pneumococcus, gonococcus, etc. Often the inflammatory process occurs as a result of the transition of the inflammatory process from the paranasal sinuses or from the face. Before redness of the eyelid skin, itching, burning, tingling, and photophobia are usually observed in the eyelash area. Swelling of the eyelids lasts 2-3 days. The formation of follicles and their purulent contents are characteristic. A large number of purulent crusts appear on the eyelashes, which dry out in infants and resemble yellow rice grains in the corners of the eyes. Later, deep pinpoint ulcers form. When the inflammatory process drags on and is not treated correctly, they merge with each other and form scars. Temperature rises to 38 °C and above. The general condition of the patient is somewhat depressed. Pus in the conjunctival cavity can melt the posterior commissure, and then liquid, the so-called scleritis, gradually accumulates. Patients feel severe pain behind the eyes. Their eyelashes fall out, the mucous membrane is hyperemic, and the eyelids are somewhat swollen. Treatment for F.K. should begin immediately after diagnosis.
