Corneal moss or ulcer

Corneal infection is manifested by bacterial moss or ulcers in the cornea, subcutaneous tissue-type dark filariasis, thin pus in subcutaneous tissue, and exudate in the cyst. If the cyst wall is not completely removed and sinus is left, it can be cured for a long time. Phaeohyphomycosis is a group of dark-colored fungi that cause skin, subcutaneous tissue, or systemic infections that are characterized by dark-colored hyphae in the tissue. This name was proposed by Ajello in 1974. There are scattered cases of filariasis in various parts of the world, but they are more common in the tropics. In recent years, sporadic cases have been reported in Shandong, Northeast China and Zhanjiang. The pathogenic pathways are mainly exogenous infections and conditional pathogenic infections. The infection may be caused by the implantation or inhalation of fungal spores by the pathogenic bacteria through the damaged skin. The clinical manifestations are superficial ulcers, petechiae, brown-black spots, or verrucous hyperplasia, conscious slight itching or mild pain, and some may have no conscious symptoms. Diagnose by mycology and histopathology. Most antifungal drugs are not sensitive and have poor efficacy.
