Is it good to apply heat to acute conjunctivitis?
Acute conjunctivitis is usually caused by bacterial infection, also known as pink eye. In the early stages of treating acute conjunctivitis, it is necessary to choose sensitive antibiotics for anti-infection treatment, such as antibiotic eye drops. Frequent application can alleviate symptoms. Generally, it is not recommended to apply heat as this can easily lead to the spread of local infection and may also lead to cross-infection. However, appropriate local cold compresses can be applied, as acute conjunctivitis is characterized by symptoms such as redness, swelling, heat, pain, and increased secretions. Local cold compresses can help reduce symptoms and relieve discomfort.
How to deal with acute conjunctivitis?
Acute conjunctivitis can also be called pink eye. It is an acute inflammatory reaction of the conjunctiva, mainly caused by bacterial infection, commonly by Staphylococcus aureus. The treatment mainly involves local anti-infection treatment, using antibiotic eye drops such as chloramphenicol eye drops, ofloxacin eye drops, or tobramycin eye drops. While using topical antimicrobial drugs, it is important to avoid rubbing the eyes with hands and avoid prolonged use of the eyes.
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.
Can retinal detachment heal by itself?
Retinal detachment refers to the separation between the neural epithelial layer and the pigment epithelial layer of the retina. Based on its cause, it can be categorized into rhegmatogenous retinal detachment, tractional retinal detachment, and exudative retinal detachment. Rhegmatogenous retinal detachment requires repositioning of the retina and closure of the break. If it is tractional retinal detachment, it is necessary to remove the cause, generally requiring vitrectomy and retinal reposition surgery. Exudative retinal detachment generally occurs due to inflammation or other irritations causing exudation or bleeding in the retina, resulting in detachment, typically without retinal breaks. This type of retinal detachment only requires treatment for the underlying disease, and aggressive treatment of the primary disease can generally lead to a cure. Therefore, retinal detachment must be treated; it cannot heal on its own.
Does retinal detachment cause eye pain?
Retinal detachment refers to the separation between the neural epithelial layer and the pigment epithelial layer of the retina at the back of the eye. Its main symptoms include flashes of light, blurry vision, and visual obstruction. It is characterized by a painless, sudden decrease in vision. Therefore, patients experiencing retinal detachment will notice flashes of light and a rapid decrease in vision prior to the condition developing, without feeling pain, thus there is no pain associated with retinal detachment.
What does a detached retina feel like?
The professional term for retinal detachment is "retinal detachment." It primarily refers to the separation between the neuroepithelial layer and the pigment epithelial layer of the retina. Early manifestations of retinal detachment may include mild vision loss, accompanied by floaters, flashes of light, or a shadow that obscures vision. As the condition progresses, symptoms gradually worsen, and when the macular area of the retina is involved, significant vision loss occurs.
Is praying to gods and worshipping Buddha effective for trichiasis?
Trichiasis generally has two types, one is simple trichiasis, which can be treated through electrolysis. By using an electric needle to destroy the hair follicle, the follicle will no longer produce eyelashes. The other type is caused by entropion of the eyelid, which requires surgical correction of the entropion to be cured. Therefore, the treatment of trichiasis needs to be conducted in a hospital; praying to gods and worshipping is of no effect and serves only as a psychological effect.
Trachoma stones are formed how?
Trachoma calculus is mainly caused by infection with Chlamydia trachomatis resulting in calculus formation. It is not actually a stone or calculus in the true sense, but rather a coagulum accumulated in the depressions or crypts of the conjunctival epithelium, consisting of desquamated epithelial cells and degenerative cells. Thus, it's not a real calculus, and is commonly seen in adults, primarily occurring in patients with chronic eye diseases such as trachoma and chronic conjunctivitis.
At what degree of myopia do you need to wear glasses?
Myopia is a refractive state in which, when the eye's accommodation is relaxed, parallel light rays from the outside, after passing through the eye's refractive system, focus in front of the retina, this condition is called myopia. The occurrence of myopia is influenced by a combination of various factors including genetics and environment. Common clinical symptoms of myopia include decreased vision, which also affects normal daily life. It is recommended to wear glasses regardless of the degree of myopia if it impacts daily activities.
The difference between amblyopia and myopia.
Amblyopia refers to a condition where, through examination, the eyeball has no organic lesions, but the vision is poor. Even after correction, the vision remains significantly lower than normal, generally less than or equal to 0.8, without any organic lesions in the eyeball. In such cases, amblyopia can be considered. Myopia, on the other hand, refers to poor vision that can reach normal or better levels after correction. The difference between the two is that amblyopia cannot be fully corrected through adjustment, whereas myopia can be completely corrected. In terms of treatment, myopia can be corrected by wearing glasses or undergoing surgery, while amblyopia can only be managed by wearing glasses or undergoing specific amblyopia treatments.
