Ptosis

Ptosis is when the upper eyelid droops over the eye. The eyelid may droop just a little, or so much that it covers the pupil. Ptosis can limit or even completely block a normal vision. Children and adults can have ptosis and can affect cosmetic appearances.

Ectropion

Ectropion is a condition in which your eyelid turns outward. This leaves the inner eyelid surface exposed and prone to irritation. Ectropion is more common in older adults, and it generally affects only the lower eyelid.

Entropion

Entropion is a condition in which your eyelid turns inward causing eyelashes and skin rubbing against the eye surface. This causes irritation and discomfort. When you have entropion, your eyelid may be turned in all the time or only when you blink hard or squeeze your eyelids shut.
