What do you do if a small Descemets perforation occurs during the dissection, but a deep anterior chamber is maintained?
The normal non-penetrating open-angle glaucoma procedure can continue if the size of the perforation is estimated to be less than 1.5mm. A valuable step in the procedure is to decompress the anterior chamber with a parasentesis as soon as Schlemm’s canal is located and prior to creating a Descemet’s window. This intraocular pressure reduction often avoids a macro-perforation caused by the iris being pushed through the opening by higher pressures. When positioning the AquaFlow glaucoma implant in these cases, the device should be positioned over the micro-perforation and used as a tampanade to control the flow.
