Distichiasis – Congenital and Acquired

  • Distichiasis is a condition in which an extra row of eyelashes occupy the usual site of meibomian glands
  • It is of 2 types
    • Congenital distichiasis
      • The meibomian glands open into the hair follicles of the extra row of eyelashes as ordinary sebaceous glands
      • The eyelashes are directed backwards and may require epilation if they rub on the cornea
    • Acquired distichiasis (metaplastic lashes)
      • The meibomian glands undergo metaplasia to form hair follicles
      • It is seen in conditions like late stage of cicatrizing conjunctivitis due to chemical injury, Stevens-Johnson syndrome, ocular cicatricial pemphigoid
