Purpose: To compare treatment areas and navigated macular laser photocoagulation (MLP) plans suggested by retro-mode scanning laser ophthalmoscopy (RM-SLO) image versus optical coherence tomography (OCT) retinal thickness map. Methods. 45 eyes of patients aged 63,1±10,2 years with diabetic or retinal vein occlusion-related ME were subjected to navigated MLP on the basis of OCT maps and RM-SLO images imported to NAVILAS navigated laser system. The plans for coagulant quantity based on OCT and RM-SLO images and the areas of retinal edema revealed by each method were compared. Results. The average number of laser spots using RM-SLO and OCT template was 171,2 ± 75,1 vs 125,9 ± 59,2 respectively, p = 0,002. The average area of edema on RM-SLO image was larger than that on OCT maps (14,9 ± 4,1 мм2 vs10,2 ± 2,9 mm2, p = 0,007) because of a larger scanning area. Conclusion. The RM SLO image can be used to guide MLP. The treatment areas suggested by RM-SLO-guided MLP plans for ME were shown to be larger than those suggested by OCT-guided plans // Russian Ophthalmological Journal, 2016; 3: 12-7. doi: 10.21516/2072-0076-2016-9-3-12-17
