Abstract: PURPOSE: To evaluate the long-term benefit of early targeted panretinal photocoagulation (PRP) combined with anti-VEGF therapy (IVL group) versus anti-VEGF monotherapy (IV group) in treatment-naïve eyes with macular edema (ME) secondary to ischemic RVO. METHODS: A retrospective analysis of 143 patients (85 IVL, 58 IV) with ischemic RVO. Baseline ischemic index (IsI), central retinal thickness (CRT), best-corrected visual acuity (BCVA), and age were adjusted. RESULTS: Over 48 months, the IVL group showed a reduction in mean CRT from 475.6 ± 117.3 μm to 282.0 ± 69.5 μm and improved BCVA from 0.61 ± 0.34 LogMAR to 0.44 ± 0.34 LogMAR. The IV group demonstrated CRT reduction from 479.4 ± 135.5 μm to 340.9 ± 127.3 μm and BCVA improvement from 0.58 ± 0.32 LogMAR to 0.50 ± 0.43 LogMAR. The IVL group received 26.0 ± 8.6 intravitreal anti-VEGF treatments (IVT), compared to 25.5 ± 6.2 IVT in the IV group. CONCLUSIONS: The IVL group exhibited a trend toward better treatment response, particularly in patients with severe retinal ischemia, though findings were not statistically significant. Baseline IsI quantification is recommended for optimal RVO management.
