 a: Panoramic FFA of the right eye of Patient 7 in group I before treatment with
additional PRP. A transparent sheet on which was drawn radial peripapillary capillaries,
optic papilla, temporal raphe, and mid-periphery (8.2 optic disc diameter)
indicated by a large circle and the extreme periphery beyond the large circle [12],
was placed on the photograph.
b: PRP spots were traced digitally along the right margin and painted black on
the sheet.
c: schematic image of PRP density in the mid periphery (30.0%).
d: Panoramic FFA of the same eye after completion of PRP. PRP density exceeded
more than 40 % in the mid-periphery and extremely periphery.
e: Schematic picture of PRP density in the mid-periphery after completion of
PRP (56.6%). |
