Comprehensive Detection, Grading, and Growth Behavior Evaluation of Subthreshold and Low Intensity Photocoagulation Lesions by Optical Coherence Tomographic and Infrared Image Analysis

Figure 2

showing representative lesions for 6 consecutive, OCT-based damage classes as defined in a former study [23]. Illustrations of each class are shown at the top of the columns and below representative OCT images taken before the treatment and 1 hour, 1 month, 3 months, and 6 months after the treatment. Classes 3 and 5 may have different OCT appearances, depending on irradiation diameter and exposure-time. All images in a column show the same fundus lesion during follow-up. If an OCT image series shows more than one lesion, a black box demarcates the lesion of interest. At the bottom, the corresponding greatest linear diameters (GLD) are given for all time points, and below that the legend and abbreviations are defined. Physical parameters and clinical images of the same set of lesions are shown in Figure 3.
