A representative example of spectral-domain OCT testing showing baseline macular thickness and volume (a), a subsequent increase in thickness and volume at month 3 after PASCAL PRP (b), and then a return to approximate baseline levels at month 6 (c) with observation only (no anti-VEGF or focal laser treatment).
