Purpose: To evaluate the morphological changes of ciliary body in eyes underwent diode laser transscleral cyclophotocoagulation (TSCPC). Methods: Five eyes of three patients with serious glaucoma were involved in this study after the informed consent. TSCPC was performed using the G-probe connected to diode laser system (Oculight SLx, Iris Medical Instruments, CA). The laser applications were delivered to three quarters of the circumference of the ciliary body. At each application, the duration and power of the laser emission and whether audible pop sound was emitted or not were recorded. The patients were clinically followed up, including tonometry and ultrasound biomicroscopy (UBM), more than six months after TSCPC. Results: The findings of UBM showed the disruption of ciliary body at the coagulated sites accompanied with the pop sound, three days after TSCPC. Such a disruptive finding of the ciliary body was not observed at coagulated sites without the pop sound. The disruptive findings disappeared and normal morphology of the ciliary body was restored by the four weeks after TSCPC. Six months after TSCPC, the ciliary body was observed to be reduced in volume. The mean intraocular pressure was 31.1 +/- 7.9 (mean +/- SEM) mmHg before TSCPC and 14.5 +/- 1.8 mmHg six months after that. In our cases, although pop sound was frequently accompanied with the treatment, no complications were observed except for floating inflammatory cells and bleeding in the anterior chamber during one or two weeks just after TSCPC. Conclusions: Using UBM, we documented the disruptive findings of the ciliary body associated with pop sound in TSCPC. Even though pop sound was emitted in TSCPC, no serious complications occurred eventually. It is suggested that pop sound can be used as a reliable sigh to confirm the actual coagulation of the ciliary body.
