Figure 1:

Photographs of the solar eclipse on March 20, 2015, taken with a 15 cm Newtonian reflector telescope by the first author (M.C.) from Szczecin, Poland. Image A was taken at 10:21 CET, almost midway into the eclipse. In B several individual images of the eclipse have been assembled together including Image A (white box). The obscurity of the eclipse was 45.40% at 10:21 CET.

Color fundus photograph (CFP) of the right eye in a patient with solar retinopathy (A). Near-infrared fundus autofluorescence image (NIR-AF) of the right eye in the same patient (B). Macular damage diameter was measured (white arrows) in both images yielding a result of 139 μm in the CFP image and 231 μm in the NIR-AF image.

Eclipse Retinopathy Injury Scale for the classification of acute macular damage caused by unprotected solar eclipse viewing

score calculated Er diameter of macular damage grade
1 point Er = 12–35 cal cm-2 min-2 100–150 µm 2 points – grade 1
2 points Er =35–140 cal cm-2 min-2 150–200 µm 3 points – grade 2
3 points Er >140 cal cm-2 min-2 >200 µm 4 points – grade 3
5 points – grade 4
6 points – grade 5
