2. Congenital lid condition
1.Epicanthus:-
Most common congenital lid condition.
Unilateral or bilateral.
Epicanthus is a condition in which a fold of
skin stretches from the upper to the lower
eyelid, partially covering the inner canthus.

3. 2.Telecanthus:-
Telecanthus is an increased distance between
the inner corners of your eyelids (medial
canthi).
• It’s usually a symptom of a genetic disorder.
Telecanthus often occurs with other eye
issues that may affect eyesight.
• Surgical correction is the main treatment for
telecanthus by plastic surgery.

4. 3.Lid coloboma:-
• Eyelid coloboma is a rare congenital
condition where there is an absence of the
development of eyelid tissue.
• Unilateral or bilateral and upper or lower
Eyelid
• Treatment: Urgent plastic repair at a
very early age to prevent exposure
keratitis and corneal ulcer.

5. 4.Districhiasis:-
Distichiasis is a congenital or acquired
condition where eyelashes arise from the
meibomian glands on the posterior
lamella of the eyelid margin.
• Eyelashes may irritate cause to corneal
epithelial defects.
• May be also seen in Stevens Johnson’s
syndrome.

6. 5.Blepharophimosis:-
Blepharophimosis syndrome is a genetic
disorder that causes problems with how
eyelids develop.
If have this syndrome, have narrow eye
openings, droopy eyelids and folds of skin
on the inner part of eyes going from the
bottom to the upper corner.

7. Eyelashes Abnormalities
1.Trichiasis:-
•Inward misdirection of eyelash
which irritate the cornea and/or
Conjunctiva.

erosion
(PEE) or may cause frank corneal
ulcer.

luxuriant
eyelashes.

the lower lid.
• It is unilateral or bilateral ,most
common in lower lid.

16. INFLAMATION OF THE LIDS
1. Angular Blepharoconjunctivitis :-
Anguler Blepharoconjunctivitis involving the
lateral canthal angle of the eye (the lateral aspect
of where the eyelids meet closest to the temples).
Redness, skin scaling, and irritation will be present
in the canthus area of the eye.
Blepharoconjunctivitis is the combining of a
severe case of blepharitis and conjunctivitis.
Blepharitis is an irritation and inflammation of the
eyelids. Conjunctivitis is an irritation and
inflammation of the conjunctiva.

medication, hair dyes, cosmetics and

the eyelashes or tear production.
A• Squamous blepharitis:-

.
– Falling of eyelashes (madarosis)
– Thickening of the lid margins
-Redness ,photophobia

20. B. Ulcerative blepharitis:-
Ulcerative blepharitis is usually caused by bacterial infection
(usually staphylococcal) of the eyelid margin at the origins of
the eyelashes.
It may also be due to virus ( herpes simplex).

bleeding.

yellowish streaks shining through
the conjunctiva

22. 6.Stye(Hordeolum):-
External hordeolum:-
• An external hordeolum arises from a
blockage with secondary inflammation of the
