- Glaucoma tube implant surgeries (aqueous shunting procedures) have become an increasing popular alternative to conventional filtration surgery in patients with refractory glaucoma (previous failed glaucoma surgery or poor surgical prognosis).
- Early post-operative complications associated with tube shunt insertion include ocular hypotony, inflammation, bleeding, infection or blockage of the tube.
- Late postoperative complications include corneal edema due to a persistent flat chamber from hypotony, corneal decompensation from tube-cornea touch, cataract, tube migration, scleral erosion, and diplopia.
- Observation for bleeding, worsening hypotony, increasing IOP or inflammatory signs.
- Medical treatment for inflammation or infection.
- Tube repositioning or exchange.
- Penetrating keratoplasty for decompensated cornea.
