Purpose: To examine the effects of panretinal photocoagulation (PRP) using a pattern scanning laser (PASCAL)system on the retinal nerve fiber layer (RNFL) thickness in patients with diabetic retinopathy. Methods: This retrospective study included 105 eyes with diabetic retinopathy, which consisted of three groups:the PASCAL group that underwent PRP with the PASCAL method (33 eyes), the conventional group that underwentconventional PRP treatment (34 eyes), and the control group that did not receive PRP (38 eyes). Theperipapillary RNFL thickness was measured by optical coherence tomography before, six months, and oneyear after PRP to evaluate the changes in peripapillary RNFL. Results: The RNFL thickness in the PASCAL group did not show a significant difference after six months (average3.7 times, p = 0.15) or one year after the PRP (average 3.7 times, p = 0.086), whereas that in the conventionalgroup decreased significantly after six months (average 3.4 times, p < 0.001) and one year after PRP(average 3.4 times, p < 0.001). Conclusions: The results of this study suggest that the PASCAL system may protect against RNFL loss by usingless energy than conventional PRP.
