↵The number of intersections on a grid which lay within the confines of tracings of the entire lesion and the classic component made on the 30 seconds angiographic frame were counted. Similarly the distance from the geometric centre of the fovea to healthy retina was measured on the same frame. The mean and the interquartile range of the number of intersections and the distance from fovea to healthy retina are shown for better and worse eyes.
