Arlt's line

Arlt's line is a thick band of scar tissue in the conjunctiva of the eye, near the lid margin,[1][2] that is associated with eye infections. Arlt's line is a characteristic finding of trachoma, an infection of the eye caused by Chlamydia trachomatis.[2] The line runs horizontally, parallel to eyelid, and is found at the junction of the anterior one third and posterior two thirds of the conjunctiva.[1]

The line is named after the Austrian ophthalmologist Carl Ferdinand von Arlt.
