21
Q

Out rolling or outward turning of the lid margin

  • ECTROPION
  • SYMBLEPHARON
A

ECTROPION

“outward turn”

22
Q

In this condition, lids become adherent with the eyeball as a result of adhesions between the palpebral and bulbar conjunctiva.

  • ECTROPION
  • SYMBLEPHARON
A

SYMBLEPHARON

“adhesion bet. palpebral and bulbar conjunctiva”

23
Q

This is very rare, but may be seen in Down syndrome and blepharophimosis syndrome.

  • Congenital ectropion
  • Involutional ectropion
A

Congenital ectropion

24
Q 
It is the commonest variety and involves only the lower lids. It occurs due to following age-related changes:
• Horizontal laxity of eyelid,
• Medial canthal tendon laxity,
• Lateral canthal tendon laxity, and
• Disinsertion of lower lid retractors.
  • Congenital ectropion
  • Involutional ectropion
A

Involutional ectropion

“age-related changes”

25
It occurs due to scarring of the skin and can involve both the lids. * Cicatricial ectropion * Paralytic ectropion * Mechanical ectropion
Cicatricial ectropion "scarring of the skin"
26
It results due to paralysis of the seventh nerve. It mainly occurs in the lower lids. * Cicatricial ectropion * Paralytic ectropion * Mechanical ectropion
Paralytic ectropion "paralysis of 7th nerve"
27
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
Mechanical ectropion "pulled down"
28
LID MARGIN IS OUTROLLED. 1. The fornix is also visible. 2. Lid margin is everted and palpebral conjunctiva is visible. 3. In it only punctum is everted. * Grade I * Grade II * Grade III
1. Grade III 2. Grade II 3. Grade I 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.
29
Paralytic ectropion results due to paralysis of the _________ * third cranial nerve * seventh cranial nerve
seventh cranial nerve
30
This happens when a tumor or other mass in your eyelid pulls the eyelid down. * Cicatricial ectropion * Paralytic ectropion * Mechanical ectropion
Mechanical ectropion "eyelid down"
31
It results from healing of the kissing raw surfaces upon the palpebral and bulbar conjunctiva. * ECTROPION * SYMBLEPHARON

32
Common causes are thermal or chemical burns, membranous conjunctivitis, injuries, conjunctival ulcerations, ocular pemphigus and Stevens-Johnson syndrome. * ECTROPION * SYMBLEPHARON

39
It is usually associated with symblepharon. * ANKYLOBLEPHARON * BLEPHAROPHIMOSIS * LAGOPHTHALMOS

40
In this condition the extent of the palpebral fissure is decreased. It appears contracted at the outer canthus. * ANKYLOBLEPHARON * BLEPHAROPHIMOSIS * LAGOPHTHALMOS
BLEPHAROPHIMOSIS
41
a congenital anomaly in which the eyelids are underdeveloped such that they cannot open as far as usual and permanently cover part of the eyes. * ANKYLOBLEPHARON * BLEPHAROPHIMOSIS * LAGOPHTHALMOS
BLEPHAROPHIMOSIS
42
This condition is characterised by inability to close the eyelids voluntarily. * ANKYLOBLEPHARON * BLEPHAROPHIMOSIS * LAGOPHTHALMOS
LAGOPHTHALMOS
43
It is characterised by incomplete closure of the palpebral aperture associated with features of the causative disease. * ANKYLOBLEPHARON * BLEPHAROPHIMOSIS * LAGOPHTHALMOS
LAGOPHTHALMOS
44
It refers to the involuntary, sustained and forceful closure of the eyelids. * BLEPHAROSPASM * PTOSIS
BLEPHAROSPASM
45
It is a rare idiopathic condition involving patients between 45 and 65 years of age. * Essential (spontaneous) blepharospasm * Reflex blepharospasm
Essential (spontaneous) blepharospasm
46
It usually occurs due to reflex sensory stimulation through branches of fifth nerve (trigeminal) * Essential (spontaneous) blepharospasm * Reflex blepharospasm

47
Abnormal drooping of the upper eyelid * BLEPHAROSPASM * PTOSIS * LID RETRACTION
