Trichiasis describes eyelashes growing in which direction relative to origin?

Explanation:
Trichiasis is when the eyelashes grow inward toward the eye, rubbing against the cornea and conjunctiva. That inward, toward the eyeball direction is described as posteriorly relative to the eyelid margin. Normal lashes grow outward from the lid margin, away from the globe, so an inward (posterior) direction is what defines trichiasis. The other directions describe outward or horizontal growth and don’t match the inward misdirection that causes the irritation and potential corneal damage.
