What condition is characterized by the misdirection of eyelashes toward the globe?

Trichiasis is the condition described by the misdirection of eyelashes towards the globe of the eye. This can occur when the eyelashes grow abnormally, causing irritation and potential damage to the cornea, as they continuously rub against the eye surface. Patients with trichiasis may experience discomfort, tearing, and increased risk of infections due to the abnormal positioning of the lashes.

Other conditions mentioned have distinct characteristics that differentiate them from trichiasis. For instance, epiblepharon involves an additional fold of skin that may cause eyelashes to misdirect, but it is primarily a cosmetic issue rather than an abnormality of eyelash growth. Entropion refers to the inward turning of the eyelid, which can lead to similar symptoms as seen in trichiasis, but it involves the eyelid itself rather than the eyelashes specifically misdirecting. Ectropion, on the other hand, involves the outward turning of the eyelid, leading to exposure of the inner eyelid, rather than misdirected eyelashes.

Understanding these distinctions clarifies why trichiasis is the correct answer for the condition that specifically involves the misdirection of eyelashes towards the eye.
