B30.1

Clinical Causes: Infection by adenoviruses, a group of viruses that are common causes of respiratory illnesses, gastrointestinal infections, and conjunctivitis. Exposure to contaminated water, such as swimming pools or lakes, where the virus can survive in the water and infect the eyes. Close contact with an infected person, particularly through hand-to-eye contact or sharing towels and eye makeup. Environmental factors that facilitate virus transmission, including crowded conditions and poor hygiene.

Key Symptoms: Redness in the affected eye, often starting in one eye and potentially spreading to the other. A watery or mucous discharge from the eye, which may become thick and whitish or yellowish. Itching, grittiness, or a burning sensation in the eye. Sensitivity to light, known as photophobia. Swelling of the eyelids and conjunctiva. Foreign body sensation, as if something is in the eye. Possible fever or sore throat if associated with other viral symptoms.

Diagnosis Path: The diagnosis of adenoviral conjunctivitis is primarily clinical, based on the characteristic appearance and typical symptoms. An eye care professional will observe the eye for redness, swelling, and discharge. In some cases, laboratory tests such as eye swabs or conjunctival scrapings may be performed to confirm the presence of adenoviruses, particularly in outbreak situations or when the diagnosis is uncertain. These tests can include viral culture, polymerase chain reaction (PCR), or rapid antigen detection methods.

Treatment Protocols: There is no specific antiviral treatment for adenoviral conjunctivitis. Management mainly focuses on relieving symptoms and preventing transmission. Recommended approaches include: - Using artificial tears to soothe the eyes. - Applying cold compresses to reduce inflammation and discomfort. - Maintaining strict hygiene practices, such as frequent handwashing and avoiding touching or rubbing the eyes. - Disposing of contaminated towels, pillows, or eye cosmetics used during infection. - Avoiding contact with others to prevent spread, especially in communal settings. In some cases, healthcare providers may recommend antihistamine or anti-inflammatory eye drops to alleviate symptoms. Antibiotics are ineffective against viral infections and are only prescribed if bacterial superinfection occurs. The condition typically resolves within one to two weeks, but good hygiene and isolation are crucial to minimize spreading the infection.
