A Computational Model of Peripheral Photocoagulation for the Prevention of Progressive Diabetic Capillary Occlusion

Figure 5

Evaluation of dot pattern size and thinned and shortened band patterns. Replicate simulations with results as box and whisker plots for dot and band pattern burns of different dimensions. Estimated outcome from commonly used panretinal photocoagulation with 1500 burns and 500 micron spots was marked with a green line in panels (b), (d), and (f). (a) Normalized area of dot burns plotted on the -axis and the replicate results plotted on the -axis. (b) Side lengths are given on the -axis and the sum of the ischemic area and burn area is given on the -axis. (c) Replicate outcomes for thinned band pattern photocoagulation therapies at a constant length of 300 microns with normalized band areas corresponding to the different band widths on the -axis and normalized ischemic area on the -axis. (d) Replicate simulations were executed for band patterns with the widths given on the -axis and the sum of the ischemic area and burn area given on the -axis. (e) Replicate outcomes for shortened band patterns at fixed band width of 60 microns with normalized band areas corresponding to the different band lengths on the -axis and normalized ischemic area on the -axis. (f) Replicate simulations for band patterns with the lengths given on the -axis and the sum of the ischemic area and burn area given on the -axis.
