Trichiasis (/trɪˈkaɪ.əsɪs/) is an eye condition where the eyelashes grow inward towards the eye, causing irritation and potentially serious damage. The word's spelling is based on its Greek roots: "trich-" means hair and "-iasis" means condition. The first syllable is pronounced with a short "i" sound and the second syllable has an "eye" sound. The "ch" sound at the beginning of both syllables is pronounced like a "k," as in "tree-key-uh-sis." Proper spelling is crucial when discussing medical conditions to ensure clear communication for accurate diagnosis and treatment.
Trichiasis is a medical condition which refers to the abnormal growth and direction of eyelashes. In this condition, the eyelashes or parts of them turn inward towards the eyeball, causing them to rub against the surface of the eye. It is commonly observed in elderly individuals but may also affect people of any age.
Trichiasis can result from various causes such as chronic eye inflammation, trauma, infections, congenital abnormalities, or certain systemic diseases. Regardless of the underlying cause, trichiasis can lead to discomfort, eye irritation, redness, tearing, and sensitivity to light. Prolonged rubbing of the eyelashes against the cornea may cause corneal abrasions and ulcers, which can further lead to vision problems and potential complications if left untreated.
Treatment options for trichiasis include both nonsurgical and surgical methods. Nonsurgical interventions may involve manual removal of the ingrown eyelashes or the use of special contact lenses or devices to redirect the eyelashes away from the eye. Surgical treatment, on the other hand, aims to permanently correct the abnormal eyelash growth by removing the affected eyelashes or adjusting their direction. This may be done through procedures like electrolysis, cryotherapy, or surgical excision with or without repositioning the eyelid for long-term relief.
It is crucial for individuals experiencing symptoms of trichiasis to seek medical attention from an eye care professional to receive an accurate diagnosis and appropriate management, which can help alleviate discomfort and preserve eye health.

The word "trichiasis" comes from the combination of two Greek words. "Trichos" (τριχώς) means "hair", and "iasis" (ιασις) means "disease" or "condition". Therefore, the etymology of "trichiasis" translates to a condition or disease related to hair. In the case of trichiasis, it refers to a medical condition where eyelashes grow inward towards the eye, causing irritation and discomfort.
