Brief Summary
Although the number of wet AMD patients with the better visual acuity is increasing, the visual improvement in patients with the better vision may not be so significant after anti-vascular endothelial growth factor (VEGF) treatments because of 'ceiling effect'. The aim of current study is to investigate the improvement of visual function after aflibercept treatments using microperimetry in wet AMD patients with the better baseline visual acuity (≥20/40).

Eligibility Criteria
You may qualify if:
- Age equal to or older than 50 years
- Treatment Naïve with active subfoveal choroidal neovascularization (CNV) lesion secondary to age-related macular degeneration (AMD) in the study eye
- Baseline visual acuity equal to or better than 20/40
- Ability to provide written informed consent and comply with study assessments for the full duration of the study
- Willingness and ability to undertake all scheduled visits and assessments
You may not qualify if:
- Sub- or intra-retinal hemorrhage that comprises more than 50% of the entire lesion in the study eye
- Scar, fibrosis or atrophy involving the center of the fovea in the study eye
- Presence of CNV in either eye due to other causes, such as ocular histoplasmosis, trauma, multifocal choroiditis, angioid streaks, history of choroidal rupture or pathologic myopia
- Presence of retinal pigment epithelial tears or rips involving the macula in the study eye
- Presence of macular hole at any stage in the study eye
- Any concurrent macular abnormality other than AMD in the study eye including epiretinal membrane, macular telangiectasia, retinal vascular abnormality.
- History of intraocular surgery except cataract operation
- Any previous intravitreal treatment to treat neovascular AMD in study eye.
- Spherical equivalent of the refractive error in the study eye demonstrating more than 8 diopters of myopia
- Presence of glaucoma that affect visual field in the study eye
- Uncontrolled ocular hypertension in the study eye (defined as intraocular pressure ≥ 25 mg despite treatment with anti-glaucoma medication) in the study eye
- History of allergy to the fluorescein sodium for injection in angiography
- History or clinical evidence of diabetic retinopathy much severe than mild non-proliferative diabetic retinopathy or diabetic macular edema in either eye
- Stroke, transient ischemic attacks, or myocardial infarction within 90 days prior to screening
- Prior treatment involving macula with photodynamic therapy with verteporfin, transpupillary thermotherapy, radiation therapy, or retinal laser treatment in the study eye, and such medications will not be allowed during the study period.
