All 4 of my young pear trees are badly affected James and one has it on every leaf like yours. On that tree, I'm going to try using scissors to cut the affected part of each leaf off (if the spots are near the tip) and will remove the whole leaf if the spots are near the base. That way there will at least be some leaf area left. It's important to remove them before the underneath starts producing a lumpy growth as it is that which releases more spores.
As I have no young pears growing, I'm tempted to also spray with a fungicide although those shouldn't be used on edible crops but I would hope the chemicals would be gone by next spring..
