G-Probe glaucoma device performs transscleral cyclophotocoagulation (TSCPC) to lower IOP through selective ablation of the ciliary processes. This simple, yet effective repeatable procedure can be performed in the office, operating room, or in conjunction with other procedures, like cataract surgery.
PLACEMENT
Hold the G-Probe™ parallel to the visual axis with the shorter edge of the footplate firmly between the anterior border and the middle of the limbus. Laser delivery is transscleral.
APPLICATIONS
Successive applications are spaced one-half the width of the G-Probe footplate apart by aligning a side of the probe over the indented center of the adjacent application.
TREATMENT
Administer 18-21 laser applications per treatment session over 270° (three quadrants, six or seven applications per quadrant), usually omitting the temporal quadrant.
G-Probe treatment parameters are suggested by IRIDEX and are based on recommendations by experienced clinicians. Ultimately, it is the physician’s responsibility to determine appropriate treatment parameters for each case.

This array of treatment parameters has been called the “slow coagulation” technique and has proven effective for most eyes.
