Will the inverted eyelashes grow back after being plucked?
Trichiasis, if plucked, can still regrow, and the new eyelashes may be harder than before, posing a more severe irritation to the conjunctiva and cornea of the eye, so plucking is not recommended. If there are few lashes, electrolysis of the eyelashes can be performed; if there are many, surgery can correct the trichiasis. Once trichiasis occurs, local anti-inflammatory eye drops should be used, such as levofloxacin eye drops, gatifloxacin eye drops, and eye ointment. Use tobramycin eye ointment and erythromycin eye ointment; do not apply heat, take rest, eat a light diet, reduce close work, have regular check-ups, and monitor your vision. (Please use medications under the guidance of a physician.)
Itchy eye corners conjunctivitis or keratitis
Itchy inner corners of the eyes are generally caused by medial or lateral canthal inflammation, mainly due to allergies or allergic rhinitis, or physical and chemical irritants. It is not conjunctivitis or keratitis. Conjunctivitis is characterized by the whitening of the eyeball turning red, photophobia, tearing, increased secretion, foreign body sensation, and burning sensation; Keratitis involves diseases of the pupil, primarily based on conjunctivitis but with more pronounced photophobia, mainly affecting vision severely. If keratitis is not treated actively, it can lead to a severe decline in vision, even blindness. Therefore, for these conditions, it is advised to first visit an ophthalmology outpatient clinic for a thorough examination and active treatment.
Can Polyfax eye drops be used for floaters?
Floaters generally result from vitreous opacification. For physiological floaters, it is usually not necessary to use proparacaine eye drops; instead, amide iodine eye drops and sodium hyaluronate eye drops should be used for treatment. Pathological vitreous opacification that affects vision requires further examination by an ophthalmologist and active treatment. Physiological vitreous opacification typically does not affect vision. It is only under bright light that moving objects may be seen floating in front of the eyes, which are less noticeable or disappear in dim light. Normally, taking care to rest, reducing close-up tasks, and avoiding eye fatigue should gradually lead to improvement, along with regular follow-up consultations. (Note: The use of medications should be carried out under the guidance of a professional doctor.)
What eye examinations are needed for floaters?
Common eye examinations for floaters typically include B-ultrasound of the eye, fundus photography, uncorrected visual acuity, corrected visual acuity, and intraocular pressure measurements, which help assess the extent of vitreous opacities. If the vitreous opacities are mild, meaning they are physiological, they generally do not affect vision and don’t require special treatment. Routine rest, proper eye usage, or treatment with amino iodine peptide eye drops may suffice. If the vitreous opacities are pathological, it is important to actively pursue medication or surgical treatments to attempt to restore some of the vision. Common pathological conditions associated with vitreous opacities include increased intraocular pressure, vitreous hemorrhage, and retinal pathology. (Please use medications under the guidance of a doctor)
How should acute floater syndrome be treated?
Vitreous opacity, also known as floaters, generally does not have acute attacks. Floaters can be divided into physiological and pathological types. Physiological floaters generally do not require special treatment because they do not affect vision. It's important to rest properly, use eyes correctly, and use Amupeptide eye drops when necessary. Pathological vitreous opacity affects vision and must undergo further ophthalmic examinations, such as tests for uncorrected visual acuity, corrected visual acuity, intraocular pressure, ocular ultrasound, and fundus photography. Treatment should be tailored according to the condition, especially treating the underlying cause. Vitreous opacity can affect vision, but with active treatment, vision generally can be partially restored.
Will you go blind from floaters as you get older?
Floaters generally do not cause blindness or loss of vision. Floaters can be divided into physiological floaters and pathological floaters. Physiological floaters generally do not cause changes in vision; their symptoms primarily appear under bright light, where one can see fixed floating objects in front of the eyes, appearing in various shapes, which become unclear in darker environments. In such cases, it is important to rest and use some aminoacyl iodine eye drops for improvement. Pathological floaters should prompt a visit to the ophthalmology department for serious and thorough examinations, proactive treatment, and can completely recover vision with regular follow-ups.
How to rule out glaucoma with high eye pressure?
Normal intraocular pressure ranges from 10-21mmHg. If it exceeds 21mmHg, it is considered to be increased intraocular pressure. Main symptoms of high intraocular pressure include eye distension, eye pain, tearing, photophobia, blurred vision, nausea, vomiting, headache, etc. High intraocular pressure is a primary diagnostic criterion for glaucoma, but it is not the only standard. Glaucoma can be divided into primary glaucoma, secondary glaucoma, congenital glaucoma, and mixed glaucoma. Primary glaucoma can further be subdivided into open-angle glaucoma and angle-closure glaucoma. Only during an acute attack of angle-closure glaucoma does the intraocular pressure increase, whereas open-angle glaucoma generally does not affect intraocular pressure. Therefore, the diagnosis of glaucoma mainly relies on a comprehensive assessment of the angle of the anterior chamber, intraocular pressure, visual field, visual acuity, and the condition of the optic disc.
Can flying mosquito disease go untreated for over twenty years?
If it is physiological floaters, generally there is no special treatment, and they are relatively stable and do not affect vision. Patients mainly experience floating shapes that vary in appearance in front of their eyes. Typically, these floaters are more visible under bright light and less visible or invisible under dim light. If there are not many floaters, it is advised to rest and treat the symptoms accordingly. If the patient requests treatment, therapies like amino iodine eye drops or sodium hyaluronate eye drops can be used. Treatment can improve the patient's mood, but generally, the condition does not worsen.
Can people with floaters drink alcohol?
Floaters refer to vitreous opacities, which can be classified into physiological vitreous opacities and pathological vitreous opacities. Physiological vitreous opacities generally do not affect vision. Their main symptom is that objects floating in front of the eyes become more noticeable in bright light and less visible in darker environments or at night. Drinking alcohol does not affect physiological vitreous opacities. However, pathological vitreous opacities do affect vision and require active treatment and examination to alleviate their impact on vision. For pathological vitreous opacities, it is generally advised not to consume alcohol, to follow a light diet, to rest adequately, and to undergo regular check-ups.
Can nearsightedness surgery correct astigmatism?
Surgery for nearsightedness can correct astigmatism, and surgeries for nearsightedness can be divided into corneal laser surgery and ICL surgery. Corneal laser surgery can be considered if the astigmatism is less than 400 degrees, while ICL surgery can be considered if the corneal astigmatism is less than 600 degrees. Additionally, astigmatism can be classified as regular and irregular. The treatment is generally more effective for regular astigmatism. If it is irregular astigmatism, further ophthalmologic examination should be conducted to rule out corneal and other ocular conditions.
