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.

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.
Is vitreous floaters close to retinal detachment?
Floater syndrome and retinal detachment generally have no necessary connection. Floater syndrome is the clouding of the vitreous body. Mild vitreous clouding does not affect vision and manifests as floating objects in front of the eyes. Pathological vitreous clouding that affects vision requires further examination by an ophthalmologist, including an ocular B-ultrasound to diagnose the extent of the vitreous clouding, and proactive treatment should be administered. Retinal detachment generally involves the separation of the retina from the choroid. Once a clear diagnosis of detachment is made, active treatment should be pursued promptly to restore vision as soon as possible. If the treatment is delayed, it can easily lead to retinal atrophy, resulting in the shrinkage of the eyeball.
How to treat blurry vision and floaters?
Blurry vision and floaters should prompt an examination by an ophthalmologist. Physiological vitreous opacities generally do not affect vision, but if they do, active treatment is required. Vitreous cloudiness can also be seen in patients with refractive errors, which include myopia, hyperopia, astigmatism, and presbyopia. In these cases, correct pupil dilation and optical correction should be done. After alleviating the issues with glasses, it is important to use the eyes properly, and orthokeratology can also be used. Once the prescription stabilizes, surgical treatment can be considered. However, surgical treatment generally only relieves the refractive condition and does not solve the nature of eye surrounding issues. Hence, it is crucial to use the eyes correctly and be cautious of further increase in the prescription.
Warm compress or cold compress for trachoma
Trachoma generally does not recommend hot or cold compresses, as it is caused by a Chlamydia trachomatis infection. For the treatment of trachoma, the main medications used are rifampicin eye drops, ofloxacin eye drops, and an eye ointment such as tobramycin ointment used once at night. Trachoma is somewhat contagious, mainly transmitted through contact; it is not transmitted without contact. Therefore, its contagious nature should be noted. The treatment process for trachoma is relatively slow, and recovery is also slow. It is relatively easy to reduce the symptoms in the eyes, but complete recovery is currently difficult. Therefore, it is important to persist with the medication, generally for about a month.
