24
Q 
It is the commonest variety and involves only the lower lids. It occurs due to following age-related changes:

“paralysis of 7th nerve”

27
Q

It occurs in conditions where either the lower lid is pulled down (as in tumours) or pushed out and down (as in proptosis and marked chemosis of the conjunctiva).

  • Cicatricial ectropion
  • Paralytic ectropion
  • Mechanical ectropion
A

Mechanical ectropion

“pulled down”

28
Q

Grade I: In it only punctum is everted.
Grade II: Lid margin is everted and palpebral
conjunctiva is visible.
Grade III: The fornix is also visible.
