Baseline and Week 24
Secondary outcome [1] 297987 0
Best corrected visual acuity will be tested by Early Treatment Diabetic Retinopathy Study (ETDRS) eye Charts. The patients will be asked to read letters from the top of the chart to the bottom, and the visual acuity is scored by how many letters could be correctly identified.

Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients who were diagnosed as age-related macular degeneration and have been previously treated with intravitreal Lucentis or Avastin and despite monthly injections, show persisting fluid in the macula, will be invited to participate at the Sydney Retina Clinic & Day Surgery, Australia.
All subjects will receive 2.0 mg intravitreal aflibercept injection.

Summary
Brief summary
The aim of the study is to evaluate the effectiveness of intravitreal Aflibercept in the treatment of choroidal neovascularisation secondary to age-related macular degeneration.
The hypothesis of this study is that intravitreal Aflibercept injection may be effective in causing resolution of persistent sub or intraretinal fluid in patients with previous treatment of Lucentis or Avastin.
