Table 1. Retinopathy scoring system
Retinal whole mounts were examined by fluorescence microscopy and ischemia induced retinopathy was quantified by evaluating four criteria. Points received for each criterion were summed to obtain the retinopathy score. A higher score (range: 0-13 points) indicates more severe retinopathy. This scoring system was adapted from Higgins et al. [37].
