Acute conjunctivitis, commonly known as pink eye or "fire eye," is more prevalent in spring and summer. It is a seasonal contagious disease, mainly transmitted through contact. Transmission often occurs by touching the secretions from the eyes of an infected person, shaking hands with someone who has pink eye, or by rubbing the eyes with dirty hands. Acute conjunctivitis is highly contagious, and the symptoms of eye irritation are quite severe, including sensations of stinging, burning, foreign body sensation, as well as photophobia, tearing, and purulent discharge. It is essential to seek medical attention promptly and to emphasize isolation and disinfection.

What to do with acute conjunctivitis?

Acute conjunctivitis is the acute inflammatory response of the conjunctiva, primarily caused by bacterial infection. The main treatment is the local use of antibacterials, such as tobramycin eye drops, ofloxacin eye drops, or chloramphenicol eye drops. Simultaneously with antibacterial treatment, it is necessary to practice frequent hand washing, avoid rubbing the eyes, wash the face with running water, and keep items like towels and handkerchiefs separate from others and frequently disinfected. During acute conjunctivitis, it is important to avoid contact with others, as it can be contagious through contact.

Does conjunctivitis require infusion?

Generally, conjunctivitis does not require intravenous treatment. Treatment primarily focuses on targeting the cause and applying local medications, with systemic medication used when necessary. During the acute phase, it is crucial to avoid bandaging the affected eye. The most basic method of administering medication for conjunctivitis is through eye drops, along with the application of eye ointment before sleep. When there is substantial secretion in the conjunctival sac, it needs to be flushed. In severe cases of conjunctivitis, such as gonococcal conjunctivitis, systemic antibiotics are required in addition to local medications.

Does conjunctivitis require a dietary restriction?

When we look at our phones and computers for long periods, it can lead to conjunctivitis due to eye strain. Among conjunctivitis cases, allergic conjunctivitis is the most common, especially during the spring and autumn seasons when symptoms like itchy eyes often occur. During such times, it is best to avoid spicy, irritating foods and seafood, as consuming these can exacerbate the itching. Additionally, if it is bacterial conjunctivitis, it is also recommended to limit the intake of spicy and irritating foods.

How to distinguish between viral conjunctivitis and allergic conjunctivitis?

Allergic conjunctivitis mainly presents with itching and conjunctival edema, generally without obvious secretions. Viral conjunctivitis usually has watery secretions and lacks significant itching. In terms of treatment, viral conjunctivitis is primarily treated with antiviral medications, such as aciclovir eye drops and ganciclovir eye drops. The treatment for allergic conjunctivitis mainly involves steroid eye drops and non-steroidal eye drops, and also requires the use of anti-inflammatory eye drops. Neither type of conjunctivitis should be treated with warm compresses. For allergic conjunctivitis, it is also important to avoid allergens, while for viral conjunctivitis, it is crucial to be aware of any visual impairments. (Note: The use of medications should be carried out under the guidance of a professional doctor.)
