Efficacy comparison of multipoint and single point scanning panretinal laser photocoagulation in non-proliferative diabetic retinopathy treatment

Figure 1 The laser energy in the multipoint group and single point group. A: The difference of laser energy between multi-point group and single-point group was not statistically significant (P > 0.05); B: The energy density of multi-point group was lower than that of single-point group, and the difference was statistically significant (P < 0.05). ^aP < 0.05.
