Dislocation of a posterior chamber intraocular lens resulting in the formation of pupillary block glaucoma.

  • Pupillary block glaucoma may commonly occur secondary to:
    • Aphakia or pseudophakia with either anterior vitreous displacement, dislocated anterior or posterior intraocular lens, or pupillary capture by intraocular lens implant
    • Ectopia lentis
    • Phacomorphic glaucoma due to cataractous lens intumesence
  • Management:
    • Anti-glaucoma therapy (i.e. aqueous suppressant therapy) initially
    • Miotic drops may be helpful to eliminate the pupillary block / iris bombe
    • Surgical therapy often needed (procedures may include laser iridotomy, laser iridoplasty, surgical iridectomy, or glaucoma filtering surgery)
