If you have trichiasis, it is generally not advisable to wear orthokeratology lenses until the trichiasis is treated. The treatment for trichiasis is straightforward. If there are only a few inverted eyelashes, electrolysis can be performed. If there are many, surgical treatment can be carried out. This is because trichiasis can easily lead to various pathological changes in the conjunctiva and cornea, such as conjunctivitis and keratitis. Keratitis can lead to the formation of corneal nebula, plaques, leukoma, or neovascularization. Therefore, it is crucial to treat the condition actively. Once the condition is stable and completely healed, then orthokeratology lenses can be worn. If there are only a few inverted eyelashes, electrolysis can be performed, and if there are many, surgical treatment can be considered, which is relatively simple.

Does trichiasis require a fundus examination?

Trichiasis refers to a condition where the eyelashes grow inward toward the eyeball, a sign related to the eye. Common symptoms include a foreign body sensation in the eye, photophobia, tearing, and even eye pain. Generally, an ophthalmologist can confirm the diagnosis with an examination under a slit lamp microscope. Therefore, it is not necessary to perform a fundus examination for trichiasis; a diagnosis can be clearly established just by using a slit lamp microscope examination.

Can trichiasis be treated without surgery?

Whether surgery is needed for inverted eyelashes depends on the specific situation. If it is just one or a few eyelashes irritating the eyeball and the symptoms are not significant, you can choose the local electrolysis method to destroy the hair follicles of these eyelashes, preventing their regrowth. This will not affect the appearance and can fundamentally solve the problem. However, if there are a large number of inverted eyelashes causing significant irritation to the eyeball, surgery is recommended for correction. Without surgery, long-term irritation from the eyelashes could cause irreversible damage to the eye, such as scarring or ulcers on the cornea, which could eventually affect vision. Some patients might intermittently pull out the eyelashes, but this is not advisable, as the eyelashes will grow back.

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.

What should I do if trachoma causes entropion and trichiasis?

Trachoma is a common ophthalmic disease caused by Chlamydia infection of the conjunctival tissue of the eye, resulting in inflammation. Trachoma can lead to substantial scarring of the conjunctiva. As scar tissue contracts, it can cause the eyelids to curl towards the eyeball, leading to entropion and trichiasis. Initially, it is necessary to use antibiotic eye drops to eliminate the Chlamydia infection and prevent the condition from worsening. Commonly used treatments include Levofloxacin eye drops, Rifampicin eye drops, and Sulfacetamide Sodium eye drops. Once the infection is completely eliminated, surgical correction of the entropion can be performed to alleviate the irritation caused by trichiasis to the patient's eyeball. (Please use medication under the guidance of a doctor.)

The harms of trichiasis

Trichiasis refers to the condition where eyelashes grow backward and irritate the eyeball. There are many causes of trichiasis, including eye injuries such as burns which can lead to scar formation and subsequently scarring trichiasis. Other causes include blepharitis and meibomian gland dysfunction. The harm posed by trichiasis is significant; the misdirected growth of eyelashes towards the eyeball and their constant friction can lead to conjunctival congestion, corneal opacity, ingrowth of new blood vessels into the cornea, and potentially result in keratitis and corneal ulcers.
