Retro-Mode Scanning Laser Ophthalmoscopy Planning for Navigated Macular Laser Photocoagulation in Macular Edema

Figure 3

OCT- versus RM-SLO-guided treatment plan for macular laser photocoagulation. (a) OCT retinal thickness map fails to cover the entire zone of retinal edema (area, 9.33 mm²). (b) OCT map superimposed onto the baseline image. (c) The number of laser spots placed in OCT-guided treatment planning is 149. (d) The entire zone of retinal edema is identified on RM-SLO image (entire edema area, 14.51 mm²; white dashed line represents the edema zone boundary; white square represents a 5 mm × 5 mm zone involved into OCT retinal thickness map; the area of edema identified by RM-SLO within the 5 mm × 5 mm zone is 10.18 mm²). (e) RM-SLO image superimposed onto the baseline image. (f) The number of laser spots placed in RM-SLO-guided treatment planning is 219 (i.e., more than that in OCT-guided treatment planning).
