Iridex announces new study in TVST on glaucoma treatments

Iridex (IRIX) announced a newly published study in Translational Vision Science & Technology, TVST, examining the thermal dynamics of transscleral laser treatments for glaucoma. Led by Tomas M. Grippo, MD, of the Grippo Glaucoma & Cataract Center, the study provides the first quantitative computer model comparing the thermal tissue effects of continuous wave transscleral cyclophotocoagulation, CW-TSCPC, and transscleral laser therapy using MicroPulse technology with Iridex’s Cyclo G6 Laser, G-Probe and MicroPulse P3 delivery devices. Using advanced Monte Carlo computer simulations, the authors modeled how each technique heats the ciliary body and quantified temperature peaks, duration, and thermal spread. The modeling revealed that CW TSCPC produced a 2 mm-wide zone of tissue heating with temperatures exceeding 100 degrees C for approximately 2.2 seconds. MicroPulse TLT generated a smaller 0.6-1.2 mm thermal zone and shorter duration peak temperatures, remaining below 100 degrees C. Additionally, MicroPulse TLT showed a more uniform heat distribution than CW-TSCPC.
