How will staying up late affect keratitis?
Keratitis can worsen if you stay up late. Keratitis can range from mild to severe. In severe cases, it may lead to blindness, while mild cases can usually heal within about a week with active treatment. If keratitis is not actively treated, it can eventually lead to corneal clouding such as nebula, macula, and leukoma, which can severely affect vision. Additionally, improper treatment of keratitis may lead to corneal ulcers or perforations, severely impacting vision. Another issue is recurrent keratitis, which can cause neovascularization affecting vision. Therefore, keratitis should be treated actively upon onset, with careful attention, regular follow-ups, and monitoring of vision.
Will nearsightedness be inherited?
Myopia has a certain hereditary aspect, but it is mainly caused by improper use of the eyes. Myopia is characterized by clear near vision and blurred distant vision, primarily due to changes in the eye's axial length. After the onset of myopia, it is crucial to properly dilate the pupils and conduct an optometric examination to rule out false myopia and amblyopia. Currently, the main treatments for myopia are still corrective glasses or orthokeratology lenses. Surgical treatment can also be considered for individuals aged 20 to 45. Once myopia develops, proper eye usage should be practiced, reducing close-range activities to avoid eye strain, and regular follow-ups are advised.
Can people with trichiasis undergo myopia surgery?
Generally, people with trichiasis should not undergo myopia surgery, as trichiasis primarily affects the eyeball. It causes abrasion to the cornea, affects the corneal epithelium, and can lead to neovascularization of the cornea and corneal pathology. Following the occurrence of trichiasis, surgical treatment should be considered. If there are only a few ingrown lashes, electrolysis of the eyelashes might be performed. After active treatment and once the condition has stabilized, the possibility of undergoing myopia surgery can be considered. Current options for myopia surgery include corneal laser reshaping surgery and ICL (Implantable Collamer Lens) surgery.
Can erythromycin ointment be used for keratitis?
Keratitis can be treated with erythromycin eye ointment, but it should be used at night, not during the day. Keratitis involves inflammation of the cornea, and can be classified into bacterial keratitis, viral keratitis, fungal keratitis, corneal ulcers, and corneal perforation. If not treated promptly, it can severely affect vision. After the onset of keratitis, it is important to properly use eye drops and ointment for treatment. Regular rest and a light diet should be maintained. Avoid spicy and irritating foods, do not stay up late, use your eyes correctly, do not rub your eyes with dirty hands, have regular check-ups, and monitor your vision.
Can strabismus undergo laser myopia surgery?
If it is an adult with strabismus who also has myopia, it should be considered on a case-by-case basis whether myopia surgery is appropriate. For alternating strabismus, myopia surgery might be considered, but generally, it is not recommended. Since strabismus can cause many problems for the eyes, such as inappropriate positioning of the eyeballs during movement, which can easily lead to diplopia or monocular vision, causing issues like double images or binocular vision dysfunction, meaning there is no stereo vision. Patients with strabismus should first undergo strabismus surgery, then consider myopia surgery.
How long will the keratitis caused by dry eye syndrome take to heal?
Due to the damage to the corneal epithelium caused by dry eye, resulting in keratitis, it is essential to treat it promptly. With active treatment, recovery is generally possible within about a week. Treatment mainly involves the use of sodium hyaluronate eye drops, calf serum deproteinized extract eye drops, levofloxacin eye drops, and acyclovir eye drops. At night, use eye ointment once, specifically tobramycin eye ointment. Do not apply heat, rest well, engage in appropriate physical exercise to boost the body's immunity, adjust your mindset, reduce close-up activities to avoid eye fatigue, have regular follow-ups, pay attention to the condition of your vision. Active treatment is crucial to prevent future complications like thinning of the cornea, spots, and leukoma, which can significantly impact vision and lead to severe consequences.
Can opening the eye corner cure trichiasis?
Trichiasis, if caused by epicanthus, can be corrected by canthoplasty. If it is not caused by epicanthus but by entropion of the eyelid, canthoplasty will not be effective. For trichiasis with few lashes involved, electrolysis can be used for treatment. If there are many lashes involved in trichiasis, entropion surgery can be performed. The surgery is minor and complete recovery is possible; usually, dressings are changed after surgery and recovery can be expected within about a week. If trichiasis severely wears down the cornea, active treatment should be sought to protect vision and the cornea.
Can strabismus and myopia be treated at the same time?
Surgery for strabismus and myopia cannot be performed at the same time. Strabismus involves surgery to adjust the eye muscles. There are two surgical methods for myopia: one is corneal laser ablation surgery, and the other is ACL surgery. Myopia surgery mainly requires stable vision, the patient must be over 18 years old, have a strong desire to stop wearing glasses, and have a clear diagnosis from examinations, then surgery can be considered. Strabismus must be classified; early stage paralytic strabismus is generally not advised for surgery. Concomitant strabismus may be treated surgically. If there is also refractive error, dilated refraction and prescription glasses should also be considered.
What tests should be done at the hospital for floaters?
To diagnose floaters, hospitals primarily use ultrasound B-scans, which are the most objective and non-invasive examinations, providing insights into the condition of the vitreous body. Floaters can be either physiological or pathological. Physiological floaters generally do not affect vision, and addressing them usually involves rest and proper eye care. If needed, treatment options may include Amniotic Iodine eye drops or oral intake of Lecithin Iodine complexes. However, if the floaters are pathological, proactive eye examinations and rigorous treatment are necessary. In severe cases, surgical intervention might be considered to preserve vision, as the causes of pathological vitreous opacities are diverse.
Can I pluck an inverted eyelash myself?
It is best not to pluck ingrown eyelashes yourself, as they will grow back even harder than before, and will grow irregularly in multiple directions instead of just outward. This will cause the eyelashes to grow disorderly. Ingrown eyelashes generally cause abrasion to the conjunctiva and cornea. If there are few ingrown eyelashes, treatment can be done by propping them up; if there are many, surgical treatment can be considered. To protect the corneal epithelium from ingrown eyelashes, certain eye drops like sodium hyaluronate may be used, along with anti-inflammatory eye drops like levofloxacin. With active treatment, recovery is usually complete. If not properly treated, it could gradually lead to corneal diseases, severely affecting vision.
