Purpose: To evaluate the short-term effect of intravitreal aflibercept (Eyleaⓡ; Regeneron Pharmaceuticals Inc., Tarrytown, NY, USA and Bayer, Basel, Switzerland) on the visual outcomes and retinal anatomic changes of patients with polypoidal choroidal vasculopathy (PCV).
Methods: Intravitreal Eyleaⓡ was injected into 16 eyes of 16 patients with PCV in this retrospective case study. After therapy, the patients were followed up for over 3 months. Changes in best-corrected visual acuity (BCVA) and central foveal thickness (CFT) using optical coherence tomography (OCT) and abnormal vasculature on indocyanine green angiography (ICGA) were evaluated.
Results: The mean log MAR BCVA was 0.75 ± 0.60 at baseline, 0.74 ± 0.60 and 0.71 ± 0.63 at 1 and 2 months, respectively (p > 0.05) and 0.57 ± 0.53 at 3 months (p < 0.05) after treatment. The mean CFT was 379 ± 130 μm at baseline, 281 ± 92 μm, 247 ± 54 μm, and 231 ± 51 μm at 1, 2, and 3 months, respectively, after treatment (p < 0.05). Complete resolution was 43%, 55%, and 50% at 1, 2, and 3 months, respectively in pigment epithelial detachment (PED), 67%, 83%, and 92% at 1, 2, and 3 months, respectively in subretinal fluid (SRF) and 33%, 60%, and 60% at 1, 2, and 3 months, respectively in intraretinal fluid (IRF) using OCT. The polypoidal lesions in ICGA decreased in 12 of 14 eyes (86%).
Conclusions: Intravitreal injection of Eyleaⓡ with PCV reduced CFT due to decreased retinal PED, SRF, IRF and occluded effectively the polypoidal lesion leaking. Compared with baseline, mean BCVA at the 3-month follow-up was significantly improved.
