Figure 1. Fundus angiography illustrating the grading scale used for leakage cloud classification. Following an intraperitoneal fluoroscein injection, angiograms were obtained after 1 and 6 min to determine the rate of leakage. Retinal images were collected and graded from control and neuroprotectin D1 (NPD1)-treated animals at 7 and 14 days following laser treatment. The terms Grade 0, Grade 1, Grade 2a, and Grade 2b are defined as follows: Grade 0 (D), no hyperfluorescence; Grade 1 (C), hyperfluorescence without leakage; Grade 2a (B), hyperfluorescence and late leakage; Grade 2b (A), bright hyperfluorescence and late leakage beyond treated areas.
