Eye infection

Introduction Eye infection refers to the local tissue inflammation caused by pathogens such as bacteria, viruses, fungi, and parasites invading the human eye. The most commonly infected sites include the eyelids, conjunctiva, cornea and sclera.

Cause

There are many causes of infection, including not paying attention to eye hygiene, bacterial or viral infection caused by rubbing your eyes by hand; direct or indirect infection by infected people; dust and other foreign matter entering the eye can also cause infection; mother-to-child transmission can also cause eye Department of infection.

The main infectious viruses include herpes simplex virus, varicella zoster virus, cytomegalovirus, human immunodeficiency virus, adenovirus and enterovirus.

The incubation period of eye infection is longer and the course of disease is slower. The clinical diagnosis depends on the medical history and eye signs. The diagnosis depends on fungal examination.

Histopathology, exfoliative cytology, immunofluorescence, electron microscopy, nucleic acid hybridization, and polymerase chain reaction can be used to directly detect the presence of viral particles or specific antigens in lesions. Microbiology examinations, etc.

Differential diagnosis

Symptoms of ocular infection

Acute conjunctivitis, fungal corneal ulcer, gonococcal conjunctivitis, trachoma and the like.

The incubation period of eye infections is longer and the course of disease development is slower. Clinical diagnosis depends on medical history and eye signs, and the diagnosis must be based on fungal examination. Isolation and culture of viruses is the most specific diagnostic method. After culture, enzyme antiserum or nucleic acid probe technology is used to detect reverse transcriptase activity in culture supernatants or to detect viral antigens. The isolation and culture of the virus needs to be carried out in a specific laboratory.
