The study demonstrates that combined therapy with intravitreal Aflibercept and photodynamic therapy can significantly improve visual acuity and reduce intraretinal and subretinal fluid in PPCV, achieving therapeutic effects.
Introduction To evaluate the effects of combined therapy using intravitreal Aflibercept (IVA) and photodynamic therapy (PDT) on polypoidal choroidal vasculopathy related to pachychoroid disease (PPCV). Methods Patients with PPCV were treated with PDT combined with 3 IVA injections on a monthly basis, followed by pro re nata criteria. The 12-month follow-up consisted of multiple revaluations of visual acuity and SS-OCT parameters of clinical activity. Results Nineteen eyes were included in the study; mean age was 65.5 years. Visual acuity improved after 12 months (0.35 +/- 0.25 to 0.2 +/- 0.20 logMAR, p = 0.005). Percentage of eyes with intraretinal and subretinal fluid reduced from baseline to the 12-month follow-up (from 52.6 to 10.5%, p = 0.12, and from 89.5 to 5.3% p = 0.0009, respectively). Central retinal and mean macular thicknesses reduced (258 +/- 39.6 to 204.8 +/- 38.8 mu m p = 0.04 and 293.8 +/- 32.1 to 248.1 +/- 29.6 mu m p = 0.017, respectively). Central choroidal and mean choroidal thicknesses also displayed a reduction (328.6 +/- 54.9 to 289.8 +/- 44.6 mu m p = 0.001 and 314.5 +/- 55.3 to 287.9 +/- 47.6 mu m p = 0.015, respectively). The mean number of injections was 4.6/year. Conclusion The results support the use of a combined therapy with Aflibercept and PDT in PPCV. This treatment would act in synergy, with anti-VEGF controlling exudation and PDT closing the aneurysmal vessel and reducing choroidal congestion.
