Entropion is treated surgically by removing a part of the eyelid skin to correct the entropion and prevent the eyelashes from irritating the conjunctiva or the cornea. The surgical outcomes for this condition are generally good. Over time, as eyelids may become more lax, entropion can recur. However, this is not considered a recurrence but rather a progression of the condition. Following these occurrences, the primary focus should be on maintaining good eye hygiene, proper eye usage, avoiding staying up late, consuming a bland diet, and avoiding spicy and irritating foods. Regular follow-ups are recommended, along with consuming fruits and vegetables that are high in vitamins E, A, and C.

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.

What will happen if trichiasis is not treated?

If trichiasis is not treated and allowed to progress, it can cause damage to the conjunctiva and the cornea. Particularly, corneal damage can lead to keratitis and corneal neovascularization, severely affecting vision and the transparency of the cornea. During treatment, if scarring occurs, such as thin corneal opacities, plaques, or leukomas, it can severely affect vision, and even lead to blindness. Therefore, while trichiasis itself is not severe, not treating it can lead to serious consequences. Currently, the main treatments for trichiasis include electrolysis of the eyelashes and surgical treatment, along with the use of eye drops, which generally results in a quick recovery.

Will trichiasis cause the eyes to tear?

Trichiasis can cause the eyes to tear. Patients with trichiasis exhibit significant tearing symptoms because the cornea is rich in nerve endings and is very sensitive to foreign stimuli. In trichiasis, the eyelashes poke and irritate the cornea, thus stimulating the nerve endings and causing reflex tearing. Therefore, patients with trichiasis should be treated promptly to avoid irreversible damage to the cornea, such as scars or corneal ulcers. For minor trichiasis, local electrolysis can be used to destroy the hair follicles so they no longer grow; for more severe cases, it is recommended to visit a hospital for surgical correction of the trichiasis.

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.

Will there be scars after entropion surgery?

After the surgery for trichiasis, scars may remain in the eyelid area. However, because the skin on the eyelids has a strong healing ability, the scars usually are not conspicuous. Trichiasis is usually caused by a spasm in the orbicularis oculi muscle inside the eyelid, leading to entropion. Eyelashes poking toward the corneal tissue scratch the corneal epithelium with each blink, causing redness, eye pain, foreign body sensation, photophobia, and tearing. If not treated promptly, it can easily lead to keratitis and may form scars within the corneal tissue, reducing corneal transparency and thus affecting the patient’s vision. Treatment typically requires surgery to remove excess loose skin on the eyelids and to eliminate part of the spasmodic orbicularis oculi muscle, returning the eyelid to its normal position and alleviating the symptoms.
