The
Entropion

        Ashesh nagar
What it is??
• “Inward rolling of the lid margin”
A disorder of


Lid??
 NO

Eyelid
Knowing a bit of eyelid will
be helpful
     •   The tarsus
     •   Muscles of lid
     •   Glands
     •   The margin
     •   The tarsal conjuctiva
entropion   trichiasis
What causes entropion???


Disparity in length and tone between
  the
• anterior skin-muscle
        or
• posterior tarsoconjuctival lamina
  of eyelid
It menifests as…
•   Redness and pain around the eye
•   Sensitivity to light and wind
•   Sagging skin around the eye
•   Excessive tears
•   Decreased vision, especially if the cornea is damaged
1. involutional        2. cicatririal


            classification




  3.spastic           4.congenital
Involutional
     Dehisance of
      posterior lid retractors
     Laxity of canthal
      ligaments
     Vertical lid laxity
     Atrophy of orbital fat
Tx of involutional
Corrective measure                      procedure

Vertical skin-muscle shortening         Zieglar cautery

Horizontal tightening of lid at lower   bick procedure
tarsal border                           Fox procedure
 Barricading of orbicularis fibers      Weis procedure,
                                        Jone’s procedure

Tightning of orbicularis fibres         Wheeler
                                        procedure
Reattachment of inferior retractors     Jone’s procedure
Cicatricial
• cicatrization of palpebral conjunctiva.
(trauma, chemical burns, Stevens-Johnson
   syndrome, ocular cicatricial pemphigoid
   (OCP), infections, or local response to topical
   medication)
• Examination of the tarsus and palpebral conjunctiva
   usually will point to the diagnosis in these cases.
Treatment of cicatritial entropion
  • Depending on the degree of scarring and entropion,
    the etiology of the cicatricial changes, and the status
    of the tarsal plate.
  • Wedge resection
  • Tarsal fracture
  • Wies procedure
  • More extensive scarring may require oral mucous
    membrane (eg, buccal mucosa) or cadaveric dermis
    (eg, Alloderm) grafts.
Wedge resection
Spastic entropion
  ocular irritation in the form of
   inflammation
   trauma
   Recent surgery
   Tight bandaging
  or due to degeneration of
   palpebral connective tissue separating the fibers of
    orbicularis muscle
   Age related degeneration of tarsal muscle

Notes de l'éditeur

  1. Lower lid retractor repair for entropion. A. Lower lid retractor defect contributes to tarsal instability. Note the failure of attachment of the lower eyelid retractor to the inferior tarsal border. B to C. A skin-muscle flap is elevated and the orbital septum penetrated to identify the lower eyelid retractor. D to E. The lower eyelid retractor is attached to the inferior tarsal border with interrupted nonabsorbable sutures. F. Final skin closure.
  2. Transverse tarsotomy (Weis) procedure. A. A lower eyelid crease incision is made and (B) extended to full thickness of the lower eyelid. C.Double-armed mattress sutures approximate the conjunctiva and lower lid retractor to the orbicularis muscle and skin, effectively everting the eyelid margin
  3. Cicatricialentropion—upper eyelid. A. The tarsus is incised and the posterior lamella is recessed. B and C. A free graft is sutured to the edges of the recessed tarsus
  4. In 19 patients including one case that had previous surgery, improvement was immediate and sustained. However, one other patient who had previous entropion surgery did not improve as expected. The volume on toxin that tended to pull the eyelash margin away from the globe resulted in immediate improvement. The actual effect on the eyelid margin was visible within 3 to 4 days of infection. The duration of improvement varied from 8 to 16 weeks. However, a 4-year-old child showed sustained improvement for a period of 26 weeks [Table 1]. Corneal defects in two children healed following correction of entropion. No side effect was noticed.Although surgical correction of senile entropion is definitive and permanent, botulinum toxin injection results in temporary correction of senile entropion as documented in a previous study.[1,4] It is a safe and quick outpatient procedure, results in temporary but immediate improvement of the condition. The toxin has a longer effect in patients with less lower lid laxity.
