Representative cases with similar pretreatment findings but with different outcomes after half-dose verteporfin PDT.

Notes: The left column shows the fundus photographs (top), fluorescence angiographic images at a late phase (middle), and indocyanine green angiographic images at a late phase (bottom) for each case. The middle column shows a horizontally scanned optical coherence tomographic image (top), macular retinal sensitivity (middle), and fixation stability (bottom) at baseline for each case. The right column shows horizontally scanned optical coherence tomographic image (top), macular retinal sensitivity (middle), and fixation stability (bottom) 12 months after half-dose verteporfin PDT for each case. Fundus photography, fluorescein angiography, indocyanine green angiography, and optical coherence tomographic findings, and macular sensitivity, but not fixation stability, at baseline are similar in the two cases. The visual acuity at baseline was 0.5 in each case. The spot size for PDT was 4300 μm for case 9 and 3100 μm for case 11. Twelve months after half-dose verteporfin PDT, the optical coherence tomographic findings and macular sensitivity was different although fixation stability became similar in both cases. Visual acuity was 0.9 in case 9 and 0.4 in case 11.
