Is conjunctivitis contagious?

Hyperacute bacterial conjunctivitis has a short incubation period and progresses rapidly. It can be transmitted through genital-eye contact. Acute or subacute bacterial conjunctivitis, commonly known as pink eye, is highly contagious, prevalent in the spring and autumn, and is generally spread through contact with items used by an infected person. Therefore, it is essential to take preventive measures.

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 should chronic conjunctivitis be treated?

Chronic conjunctivitis is a chronic inflammation of the conjunctiva caused by various reasons, with complex etiology, mainly manifested as mild conjunctival congestion and a small amount of mucous secretion, often affecting both eyes. Chronic conjunctivitis is not self-limiting and can be difficult to treat. Treatment is targeted based on different causative factors, along with the appropriate use of antibiotic eye drops and ointments. In cases of chronic staphylococcal conjunctivitis, erythromycin responds quite well, while a broad-spectrum antibiotic eye drop, aminoglycoside eye drops, or ointments may be chosen for other bacterial causes. For cases where the above medications are ineffective, a conjunctival scraping can be performed for bacterial culture and sensitivity testing, and the medication can be adjusted based on the results.

Can you take a bath with conjunctivitis?

Patients with conjunctivitis can bathe, but should strictly pay attention to personal and collective hygiene, advocate frequent handwashing and face washing, and avoid wiping eyes with hands or sleeves. Do not share a towel with others. Patients in the acute phase need to be isolated to prevent transmission and curb the epidemic. When one eye is infected, precautions should be taken to prevent the other eye from being infected.

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.
