What are the causes of eye infection symptoms

The eyes are the most vulnerable part of the human body. If you do not pay attention to eye hygiene and often rub your eyes with your hands, it will cause bacterial or viral infection. The infected eyes are prone to inflammation, such as common conjunctivitis or keratitis. The general symptoms are eye congestion, tears when exposed to light, frequent eye mucus, and sometimes itching, accompanied by pain. Once this happens, in addition to going to the hospital for treatment, you should pay more attention to eye hygiene and avoid eating spicy and irritating foods.

reason

There are many causes of infection, including bacterial or viral infection caused by not paying attention to eye hygiene and rubbing the eyes with hands; direct or indirect infection by an infected person; dust and other particles entering the eyes and causing corneal foreign bodies can also cause infection; mother-to-child transmission can also cause eye infection.

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

examine

The incubation period of eye infection is long and the course of the disease progresses slowly. Clinical diagnosis relies on medical history and eye signs, and the final confirmation requires fungal examination.

Histopathology, exfoliative cytology, immunofluorescence technology, electron microscopy, nucleic acid hybridization and polymerase chain reaction can be used to directly examine the presence of viral particles or specific antigens in lesion specimens. Microbiological examination, etc.

Differential Diagnosis

Confusing Symptoms of Eye Infections

Acute conjunctivitis, fungal corneal ulcer, gonococcal conjunctivitis, trachoma, etc.

Eye infections have a longer incubation period and progress more slowly. The clinical diagnosis relies on medical history and ocular signs, and the definitive diagnosis must be based on fungal testing. Virus isolation and culture is the most specific diagnostic method. After culture, enzyme immunoassay or nucleic acid probe technology is used to detect reverse transcriptase activity in the culture supernatant or detect viral antigens. The isolation and culture of viruses must be carried out in a specific laboratory.

Mitigation methods

Precautions:

① Ensure the cleanliness and hygiene of the affected area and thoroughly disinfect the affected area;

② Use antibacterial eye drops appropriately;

③Avoid eating spicy food;

The ocular administration methods of antibiotics include topical drops, subconjunctival, intraocular and systemic administration. Systemic administration is necessary for infections of the conjunctiva and superficial or orbital areas. For severe conjunctival and corneal ulcers, systemic and subconjunctival injections can be used simultaneously.
