$ANNX let’s be clear
A ≥15-letter loss represents dropping three full lines on the standard ETDRS eye chart at two consecutive clinical visits. This is a functional vision preservation metric rather than a purely structural measurement of lesion growth
When a treatment prevents this from happening, it means the treatment successfully preserved real-world, usable vision for the patient, which matters much more to daily life than just slowing down a spot on a scan.
