Abstract
PURPOSE: To evaluate the 1-year results of adjunctive photodynamic therapy in patients with Type 1 neovascularization associated with thickened choroid who were refractory to anti-vascular endothelial growth factor monotherapy. METHODS: Data on 28 eyes of 28 patients with Type 1 neovascularization with a minimum subfoveal choroidal thickness of 300 μm were reviewed. All showed persistent subretinal and/or intraretinal fluid after at least 4 anti-vascular endothelial growth factor injections in the 6 months before adjunctive photodynamic therapy. No eyes had certain polypoidal lesions on indocyanine green angiography. RESULTS: At 3 months, complete fluid absorption was observed in 24 eyes (85.7%). The mean best-corrected visual acuity significantly improved (20/53-20/44, P = 0.040) and mean subfoveal choroidal thickness reduced (386 to 350 μm, P < 0.001) compared with baseline. Over a 1-year follow-up period, 17 eyes (60.7%) were free from recurrent fluid accumulation. Anti-vascular endothelial growth factor injection was mainly used in retreatment (mean: 1.5). At 12 months, best-corrected visual acuity improved by ≥0.3 logMAR or maintained compared with baseline in 27 eyes (96.4%). CONCLUSION: Adjunctive photodynamic therapy in eyes with Type 1 neovascularization with thickened choroid that were refractory to anti-vascular endothelial growth factor monotherapy resulted in complete fluid absorption in most eyes, which translated to visual improvement until 1 year.
