  3. Approaches for Ant.Vit. • Ant. Approach from limbal side port. • Pars Plana approach 3mm post to limbus.

  4. Pathogenesis • The term PCO is misleading. • A-cells : fibrousmetaplasia fibrous PCO • E-cells : mitosis PCO with ‘pearls’

  5. Other cells involved in formation of PCO • Infammatory cells –WBCs • RBCs • Collagen deposition • Iris melanocytes
