Conjunctivitis
Does conjunctivitis require isolation?
Infectious conjunctivitis can lead to epidemic infection, therefore it is essential to take preventive measures. Conjunctivitis is often spread through contact, thus it is advocated to frequently wash hands and faces, and avoid wiping eyes with hands or sleeves. Patients with infectious conjunctivitis must be isolated, and any toiletries used by the patients must be isolated and disinfected. Medical staff should also wash and disinfect their hands after examining patients to prevent cross-infection.
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.
How long is the incubation period for conjunctivitis?
Hyperacute bacterial conjunctivitis, caused by gonococci or meningococci, is characterized by a short incubation period of 10 hours to two to three days, with rapid disease progression. Acute or subacute bacterial conjunctivitis, also known as acute catarrhal conjunctivitis, commonly known as pink eye, has a sudden onset with an incubation period of one to three days, affecting both eyes either simultaneously or one to two days apart.
Does conjunctivitis require an IV drip?
Conjunctivitis generally does not require intravenous treatment; it is mainly treated according to the cause, with local administration of medication being the primary approach. Systemic medication may be required when necessary. Eye drops are the most basic method of administering medication for conjunctivitis. Eye ointment can also be applied to the eyes; since it remains in the conjunctival sac for a longer duration, it is advisable to use it before bedtime. When there is a lot of secretion in the conjunctival sac, a non-irritating rinse solution can be used to wash the conjunctival sac. In severe cases of conjunctivitis, such as gonococcal conjunctivitis and chlamydial conjunctivitis, systemic antibiotics or sulfa drugs are needed in addition to local treatment.
Trachoma conjunctivitis symptoms
Trachoma is a chronic infectious conjunctivitis and keratitis caused by Chlamydia trachomatis, which can lead to blindness. During the acute phase in both eyes, symptoms include redness, pain, foreign body sensation, tearing, and purulent discharge, along with swollen lymph nodes, increased papillary formation in the palpebral conjunctiva, and multiple follicles covering the superior and inferior fornices. After the acute phase, which lasts one to two months, it enters a chronic phase where conjunctival congestion decreases, and the conjunctiva thickens with increased papillary and follicular formation. Complications in the later chronic stage mainly include entropion and trichiasis, eyelid ptosis, symblepharon, essential keratoconjunctivitis sicca, and chronic dacryocystitis leading to corneal opacity, among others.
How long does it take for conjunctivitis to heal?
Conjunctivitis can be categorized by the speed of onset into hyperacute, acute or subacute, and chronic. Depending on the severity of the condition, it can be classified as mild, moderate, or severe. Acute conjunctivitis is usually self-limiting, with the condition lasting about two weeks. After treatment with sensitive antibiotics, recovery can occur within a few days. Chronic conjunctivitis is not self-limiting and is more challenging to treat.
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.
Conjunctivitis symptoms
Conjunctivitis is an inflammation that occurs in the thin layer of structure on the surface of the white eyeball and the inner surface of the eyelid. Conjunctivitis can be caused by infections such as bacteria, viruses, chlamydia, fungi, parasites, etc., and by environmental factors like sand, smoke, ultraviolet exposure, and chemical injuries from acids, alkalis, or toxic gases. It can also be an inflammatory response of the conjunctiva due to allergic or systemic diseases including tuberculosis, syphilis, thyroid disorders, or surrounding tissues of the eye such as the cornea, sclera, eyelids, nasal cavity, and sinuses. Common symptoms of conjunctivitis include red eyes, a sensation of a foreign body in the eye, burning, itching, photophobia (sensitivity to light), tearing, and increased discharge. Sometimes it can also cause eye pain.
What are the symptoms of conjunctivitis?
According to the onset speed of conjunctivitis, it can be divided into hyperacute conjunctivitis, acute or subacute conjunctivitis, and chronic conjunctivitis. The symptoms of conjunctivitis mainly include foreign body sensation, burning sensation, itching eyes, photophobia, tearing, and significant signs include conjunctival congestion, edema, increased secretions, papillary hyperplasia, follicles, pseudomembranes and true membranes, granuloma, and so on.
Is conjunctivitis prone to recurrence?
Conjunctivitis is a type of localized inflammation, similar to other inflammations. This disease may recur frequently, especially in children, infants, elderly or frail patients, or those with chronic debilitating diseases such as diabetes. Due to weaker bodily resistance, these individuals are more susceptible to repeated bacterial infections. To avoid such situations, it is advised to pay attention to healthy dietary habits, avoid spicy and irritating foods, and appropriately increase physical exercise to enhance resistance, thereby minimizing the chances of disease recurrence.
