The dark adaptation of 14 diabetic patients was measured before and after panretinal photocoagulation (PRP). The rod-cone break of diabetics prior to PRP was delayed 1.7 minutes compared to normal controls and the final rod threshold was elevated 0.7 log units. After PRP, the rod-cone break was delayed 2.9 minutes and the final rod threshold was elevated 1.1 log units.
对14名糖尿病患者在全视网膜光凝（PRP）治疗前后进行了暗适应测量。与正常对照组相比，糖尿病患者在PRP治疗前的视杆 - 视锥细胞转折点延迟了1.7分钟，最终视杆阈值升高了0.7对数单位。PRP治疗后，视杆 - 视锥细胞转折点延迟了2.9分钟，最终视杆阈值升高了1.1对数单位。
