- 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).
- Complications:
- 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.
- Management:
- 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.
