Trans-scleral cyclophotocoagulation: a tale of two probes

Blog Article

To compare the histological effects of trans-scleral cyclophotocoagulation (TCP) performed with two different probes, the G-probe (IRIDEX Medical Instruments, Mountain View, CA, USA) and the Ciliprobe (Katalyst Surgical, Chesterfield, MO, USA).TCP was performed microtech 184-10 on two human cadaver eyes from the same corpse.The vertical meridian was marked and opposite sides were treated using either the G-probe or Ciliprobe.The first eye was treated with each probe at 2000ms/2000 mW and the second eye at 3000ms/1500 mW.Histological examination revealed separation and loss of the non-pigmented ciliary epithelium as well yogi xiyoshi as vacuolization in all sections for both probes and settings.

Changes to the non-pigmented ciliary epithelium treated at 3000ms/1500 mW were similar between the two probes.A slightly more complete separation of the non-pigmented epithelium was noted on the Ciliprobe treated sections as compared to the G-probe treated sections in the eye treated at 2000ms/2000 mW.Therefore, in human cadaver eyes, both the G-probe and Ciliprobe produced separation, vacuolization, and loss of the non-pigmented ciliary epithelium at two different, clinically utilized settings.
