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.
Will surgery for inverted eyelashes leave scars?
The types of trichiasis can be divided into two categories. One type is simple trichiasis, where the eyelashes grow inward. Its treatment can be through electrolysis, which involves using an electric needle to destroy the hair follicle before plucking it out, preventing future eyelash growth from that follicle. The other type is caused by entropion of the eyelid, which requires corrective surgery for the inward-turning eyelid, involving an incision in the skin. Therefore, treatment of this type of trichiasis will result in scars on the skin.
Is high intraocular pressure always glaucoma?
Glaucoma is a group of eye diseases characterized by typical optic nerve atrophy and visual field defects, with high intraocular pressure and visual field loss as features. Clinically, some patients have long-term high intraocular pressure but do not exhibit optic nerve and visual field damage. This condition is not called glaucoma, but is referred to as ocular hypertension. Meanwhile, some patients may have normal eye pressure but still exhibit typical glaucoma optic nerve damage and visual field defects; this condition is called normal-tension glaucoma. Therefore, high intraocular pressure does not necessarily indicate glaucoma, and normal intraocular pressure can also potentially be glaucoma.
Does floaters need surgery?
The commonly mentioned "floaters" in ophthalmology refer to the turbidity in the vitreous body of the eyes. In most cases, this phenomenon is normal; it is a normal physiological degenerative change of the vitreal body and generally does not have much impact on vision. In such cases, surgery is not needed. However, if there is a pathological change in the eye, such as bleeding at the base of the eye, and blood flows into the vitreous body, causing turbidity, surgery can be considered if this severely affects vision.
