Abstract
Introduction:
There are a few reports investigating the treatment of aneurysmal type 1 neovascularization (AT1) in Caucasian patients. The aim of this study is to evaluate the 2-year results of a treat and extend regimen with aflibercept in Caucasian patients with AT1.
Methods:
We conducted an observational retrospective study in 28 eyes of 26 patients with naïve AT1 treated with a treat an extend regimen of intravitreal aflibercept. Best corrected visual acuity (BCVA), central macular thickness (CMT), pigment epithelium detachment (PED) height, presence of dry macula, and regression rate of polypoidal lesions were assessed at baseline and at 12 and 24 months.
Results:
BCVA was significantly increased by 9.03 ± 16 letters (p < 0.01) and 9.2 ± 16.87 letters (p < 0.01) after the 12 and 24 months follow-up. A significant decrease of CMT was found at 12 and 24 months (p < 0.01). Nevertheless, significant changes in PED height were not observed (0.1 < p > 0.05). At 12 and 24 months of follow-up, dry macula was achieved in a total of 10 eyes (35.71%) and 15 eyes (53.57%). The regression rate of polypoidal lesions was 25% (7 eyes) and 35.71% (10 eyes) after 12 and 24 months. The mean number of intravitreal injections was 7.81 ± 3.20 the first year and 6.11 ± 3.49 the second year.
Conclusion:
To the best of our knowledge, treat and extend regimen with intravitreal aflibercept in Caucasian patients may be effective for improving BCVA, CMT, wet macula, and regression rate of polypoidal lesions.
