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.

Can trichiasis cause corneal damage?
If trichiasis persists in rubbing against the cornea, it will cause damage to the cornea. Long-term abrasion can lead to corneal neovascularization, damage the corneal epithelium, and leave opacity, sometimes forming speckled opacity or even leukoplakia, severely affecting vision. Once trichiasis occurs, active treatment is necessary. If there are only a few lashes involved, electrolysis of the eyelashes can be done; if there are many, surgery is essential. The surgery for trichiasis is generally successful, fully capable of correcting the condition, protecting the cornea, preserving vision, and alleviating the symptoms of the patient.

Does trichiasis need to be corrected?
Trichiasis must be treated because it can cause damage to the conjunctiva and cornea. Damage to the cornea can lead to unnecessary corneal inflammation, thinning of the cornea, spotty opacity, scarring, and neovascularization, seriously affecting vision. Therefore, proactive treatment is essential. If there are only a few lashes involved in trichiasis, electrolysis can be used for treatment. If there are many lashes involved, surgical treatment is necessary. During this period, anti-inflammatory eye drops should be used, such as levofloxacin eye drops and erythromycin eye ointment, along with eye drops that protect the corneal epithelium, such as sodium hyaluronate and calf blood deproteinized extract drops. With these treatments, complete recovery is possible. (Please use medication under the guidance of a doctor)

The difference between trachoma and stye
Trachoma is a chlamydial infection, while a stye is an infection caused by Staphylococcus aureus. Trachoma manifests as the formation of trachoma follicles, hyperplasia, and inflammation on the inner surfaces of the eyelid and conjunctiva, with symptoms including redness, swelling, pain in the eyes, neovascularization of the cornea, and vascular pannus. A stye presents with redness, swelling, heat, and pain in the eyelid, mainly caused by inflammation. In terms of treatment, trachoma mainly uses rifampin eye drops; styes are treated with levofloxacin eye drops, and erythromycin or tobramycin ointment at night, with no hot compresses applied. Typically, a stye can heal within about a week, whereas trachoma requires a longer treatment period, and it is important to rest and undergo regular check-ups. (The use of medications should be carried out under the guidance of a physician)

What happens if glaucoma worsens?
Glaucoma, if left untreated or improperly treated leading to worsening, can result in blindness, which is referred to as absolute glaucoma. In such cases, it becomes impossible to recover vision; in other words, it is irreversible. Therefore, it is crucial to proactively treat glaucoma after its onset by reducing eye pressure to protect vision, adjusting one's mindset, resting adequately, and avoiding close-range activities. The treatment is generally quite successful nowadays. Glaucoma can be classified into acute angle-closure glaucoma and open-angle glaucoma, both of which are types of primary glaucoma. Additionally, it can be categorized into primary glaucoma, secondary glaucoma, congenital glaucoma, and mixed glaucoma. With active treatment, the outcomes for glaucoma are generally good.

Does retinal detachment cause eye pain?
After retinal detachment, there is usually no pain in the eye. Symptoms include low ocular pressure, blurred vision, and visual field defects, which means seeing things partially or missing a half. In such cases, it is important to actively seek an ophthalmological examination. This includes checking the uncorrected visual acuity, corrected visual acuity, intraocular pressure, eye ultrasound, and fundus photography. Once diagnosed, it is crucial to undergo surgery as soon as possible. The earlier the surgery is performed, the better the potential recovery of vision. Generally, there is a high possibility of restoring vision after surgery.

Can strabismus be redone if it recurs?
After strabismus surgery, if the eye alignment is still incorrect, reoperation should be considered only after six months. Additionally, one should consider the uncorrected visual acuity, corrected visual acuity, eye movement, and the condition of the eye muscles to determine whether the issue is due to refractive errors or eye muscle paralysis. Reoperation must be approached with caution. The primary cause of strabismus is an issue with the eye muscles, and this can lead to various eye diseases. Therefore, it is crucial to conduct thorough ophthalmological examinations and pay attention to the eye movement and the condition of the binocular vision system.

Is night blindness related to myopia?
Night blindness generally has little to do with myopia. Night blindness can be divided into congenital night blindness and acquired night blindness, caused by retinal dysfunction. Myopia makes distant objects appear blurry and near objects clear, primarily due to changes in the eye's axis. Night blindness does not involve changes in visual acuity or the eye's axis. Once night blindness occurs, one should actively seek an ophthalmological examination and receive proper treatment. Currently, the treatment for myopia mainly includes corrective glasses, orthokeratology (corneal reshaping therapy), and surgical treatments.
