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.
What eye drops are used for trachoma?
Once diagnosed with trachoma, not only is it necessary to use local eye drops, but also systemic treatment is required. Commonly used local eye drops for trachoma include 0.1% rifampin eye drops, 0.5% penicillin eye drops, yellow safety eye drops, tetracycline eye ointment, erythromycin eye ointment, sulfa eye ointment, and the treatment course needs at least ten to twelve weeks. In the acute phase or severe cases of trachoma, systemic antibiotic treatment is also needed, generally for three to four weeks. Adults take oral tetracycline, while it is contraindicated for pregnant women, nursing women, and children under seven years old, who may alternatively use erythromycin. Note: Medication should be used under the guidance of a doctor.
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.
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 treat refractive errors of the eyes?
Refractive error refers to the condition where, without accommodation, parallel light rays passing through the refractive media of the eye do not form a clear image on the retina, but rather form an image in front of or behind the retina. This includes hyperopia (farsightedness), myopia (nearsightedness), and astigmatism. For myopia treatment, light to moderate myopia can be corrected with appropriate concave lenses; in cases of hyperopia, if vision is normal and there are no subjective symptoms, no treatment is needed. However, if there are symptoms of visual fatigue, appropriate convex lenses should be used for correction; astigmatism requires the correction with cylindrical lenses.
Trachoma has several treatment methods.
Trachoma is a chronic infectious conjunctival and corneal inflammation caused by Chlamydia trachomatis infection and is one of the leading causes of blindness. Around three hundred to six hundred million people worldwide are infected with trachoma. Treatment includes systemic and local ocular medication, as well as treatment for complications. Local treatments include 0.1% rifampicin eye drops, 0.1% tetrahydropalmatine eye drops, or 0.5% neomycin eye drops. Erythromycin or tetracycline eye ointments are used at night, with a treatment duration of at least ten to twelve weeks. Acute or severe cases of trachoma should be treated with systemic antibiotics. Surgical correction of trichiasis and entropion is crucial to prevent late-stage trachoma scarring that leads to blindness.
Can I drink alcohol with conjunctivitis?
Conjunctivitis is one of the most common diseases in clinical ophthalmology, often caused by inflammation or viral infections. Taking anti-inflammatory drugs and alternately using ribavirin eye drops and ofloxacin eye drops for treatment yields relatively good results. Avoid staying up late, rubbing eyes with hands, and consuming spicy and other irritating foods. Abstain from smoking and drinking alcohol. Smoking and drinking during treatment can exacerbate the condition and lead to recurrent episodes.
Can conjunctivitis be contagious?
Hyperacute bacterial conjunctivitis, acute or subacute bacterial conjunctivitis is highly contagious and requires isolation to prevent spread and epidemics. When one eye is infected, measures should be taken to prevent infection of the other eye. Strict attention should be paid to personal and communal hygiene, advocating frequent hand and face washing, and avoiding wiping eyes with hands or sleeves. Strict disinfection of face washing utensils, towels, and medical instruments used by the patient is also necessary.
What is the difference between refractive error and nearsightedness?
Myopia is a type of refractive error, which refers to the condition where, when the eye is not adjusting, parallel light rays after passing through the refractive action of the eye, do not form a clear image on the retina, but rather image in front of or behind the retina. This includes hyperopia, myopia, and astigmatism. When parallel light rays image in front of the retina after passing through the eye's refractive action, it is called myopia.
