After removing the misdirected eyelashes, it generally does not significantly affect the eyes. However, if they regrow after being plucked, they tend to be harder than before. Repeated plucking can cause inflammation of the eyelid and conjunctiva, long-term abrasion of the cornea, and may lead to the formation of new blood vessels in the cornea. Sometimes, it can also lead to corneal vascularization. Therefore, plucking is not advised. If there are only a few eyelashes, electrolysis can be performed; if there are many, surgical correction is possible, and generally, the results of the surgery are quite good. In such cases, it is advisable to use anti-inflammatory eye drops and eye drops that protect the corneal epithelium, such as levofloxacin and sodium hyaluronate eye drops. (Please consult a doctor before using any medication.)

Why did a trichiasis suddenly grow?

A sudden formation of an ingrown eyelash is usually due to chronic inflammation in the eyelid margin area, which causes abnormalities in the eyelash follicles. Consequently, the direction of the eyelash growth no longer points straight forward but instead grows toward the eyeball. As the eyeball moves and blinks, the eyelash rubs against the corneal epithelium, causing noticeable symptoms such as a foreign body sensation, stabbing pain, congestion, redness, photophobia, tearing, and a decline in vision. One can visit the ophthalmology department of a hospital for a face-to-face examination and confirmation of the condition. Removing the ingrown eyelash can alleviate the symptoms, but recurrence is possible. If it recurs repeatedly, electrolysis treatment for ingrown eyelashes can be considered. This involves inserting a specially designed probe deep into the follicle of the ingrown eyelash and then passing an electric current through it. The electric current will destroy the follicle of the ingrown eyelash, making it less likely to recur.

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.

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.

Besides surgery, how can trichiasis be treated?

Patients with trichiasis can undergo electrolysis treatment for trichiasis in addition to surgical treatment to eliminate symptoms. This involves using a specially designed electric probe that enters the follicles of the misdirected eyelashes, and through the action of electric current, destroys the follicle, thereby preventing the formation of trichiasis. However, electrolysis treatment for trichiasis is only suitable for patients with a small number of misdirected eyelashes, as treating a large number of them can lead to the growth of scar tissue on the eyelid margin, causing complications such as entropion or ectropion. Patients with extensive trichiasis generally need to undergo surgery for correction and treatment.

Can trichiasis be noticeable?

Trichiasis can be clearly seen with the naked eye; it causes friction on the conjunctiva, either on the sclera or the cornea, leading to damage to the corneal epithelium. This can result in keratitis, corneal neovascularization, and if not treated promptly, it can lead to further pathological changes in the cornea such as thinning, leukoma, and speckled opacities, severely impacting vision. Simple cases of minimal trichiasis can be treated with electrolysis, but more severe cases should be surgically treated. Complete recovery is possible after surgical treatment for trichiasis.
