Introduction

  • An adhesion between 2 conjunctival surfaces: between cornea and conjunctiva, or between nictitans and conjunctiva or cornea.
  • Cause: usually acquired following severe conjunctival damage, injury or infection in which apposing conjunctival surfaces lose their epithelial surface.
  • Signs: adhesion of conjunctiva to other conjunctival sites, cornea (especially limbus) or nictitans.
  • Diagnosis: signs.
  • Treatment: rarely treated unless vision impairing.
  • Profylaxis: depends on encouraging rapid and uncomplicated conjunctival healing following injury or surgery.
  • Prognosis: variable, recurrence common.

Pathogenesis

Etiology

  • diseases causing conjunctival ulceration , such as chemical burns.
  • Conjunctival injuries.
  • Bacterial infection in association with conjunctival injuries or diseases.
  • Surgical incisions. If not primarily closed, dehiscence occurs.
  • Congenital abnormality.

Pathophysiology

  • Adhesion - usually the result of a conjunctival injury or infection that results in loss of conjunctival epithelium and various amounts of stroma with subsequent apposition of ulcerated surfaces.
  • Rarely seen as congenital abnormality with microphthalmos.
