Fig. 5. — The percentage of PBM-treated subjects with a ≥5 letter improvement on ETDRS visual acuity from baseline over time. After each treatment series (M1 and M7), almost one half of all PBM-treated eyes showed ≥5 letter gain (50% of eyes at M1, 46% of eyes at M7). This effect was reduced over time until the next treatment series was initiated. Photobiomodulation-treated eyes that showed ≥5 letter gain were typically in earlier stages of the disease and did not have significant GA with foveola involvement.
