Summary

This case study highlights a patient with advanced primary open angle glaucoma who experienced uncontrolled intraocular pressure after cataract surgery. The findings emphasize the challenges in managing glaucoma after prior filtering surgery.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Surgical Outcomes

Background:

  • A patient with monocular vision and primary open angle glaucoma underwent filtering surgery in the right eye.
  • Cataract surgery with intraocular lens implantation was performed years later.

Observation:

  • Post-cataract surgery, the filtration bleb became avascular and shallowed.
  • The patient's intraocular pressure increased significantly and was refractory to medical management.

Findings:

  • Despite maximal medical therapy, intraocular pressure remained uncontrolled.
  • Visual field testing revealed a small central island of vision.

Implications:

  • This case underscores the potential for filtration bleb compromise after subsequent ocular surgery.

  • Management of uncontrolled intraocular pressure in such complex glaucoma cases requires careful consideration.
