PURPOSE: The purpose of this study was to compare intravitreal ziv-aflibercept (IVZ) monotherapy to intravitreal bevacizumab (IVB) monotherapy in patients with exudative age-related macular degeneration (eAMD).
MATERIALS AND METHODS: Patients with treatment-naïve eAMD treated with pro re nata (PRN) monotherapy of IVZ (1.25 mg/0.05 ml) or IVB (1.25 mg/0.05 ml) with a minimum follow-up of 12 months were retrospectively analyzed. Study outcomes included change in best-corrected visual acuity (BCVA), central macular thickness, mean number of injections, and total medication cost in both the groups at 12 months.
RESULTS: Forty-seven eyes (IVZ, 18/47 [38.3%] and IVB, 29/47 [61.7%]) from 47 treatment-naive patients were included. The change in BCVA for patients receiving IVZ was from 0.61 ± 0.33 logarithm of the minimum angle of resolution (Snellen 20/81; range: 20/38–20/174) to 0.45 ± 0.31 (Snellen 20/56; range: 20/27–20/115) at 1 year (P = 0.02). The total number of injections needed to achieve the resolution of intraretinal or subretinal fluid was 2.6 ± 1.4 and 3.5 ± 1.3 for IVZ and IVB, respectively (P = 0.029). Direct medication cost of IVZ and IVB in our cohort on PRN basis was an average of US$78 (2.6 × US$30) and US$175 (3.5 × US$50), respectively, through 1 year.
CONCLUSION: IVZ-PRN monotherapy resulted in improved visual acuity, reduced treatment burden, and reduced direct medication cost in comparison to IVB-PRN monotherapy through 1 year.
