Trabeculectomy Bleb Revision (Ab Interno)

Dr. Razeghinejad performs a cataract extraction followed by ab interno bleb revision and external bleb needling. Viscoelastic is injected to keep the eye formed. A spatula is placed from the anterior chamber through the trabeculectomy sclerostomy into the subconjunctival space. The I/A handpiece is used to pressurize the anterior chamber, which demonstrates that the bleb is still encapsulated. Bleb needling is then performed to break the subconjunctival adhesions and develop a responsive bleb.
