Study summary

The study will assess the mean change in Visual Acuity (VA) (overall and stratified by baseline VA) at year 1 and 2 of treatment with Aflibercept in real-life setting.

In addition, the study will ascertain the baseline VA in treatment -naïve Wet Age-Related Macular Degeneration or neo-vascular AMD (wAMD) patients who start treatment with Aflibercept in a real-life setting and it will assess the impact of baseline VA on the outcomes of Aflibercept treatment.

What researchers measure

Primary outcomes

  1. Change in Visual Acuity (VA) (Snellen)

    Change in VA (Snellen) at 3±1 months, 6±1months, 12±2 months and at 24±2 months follow-up in all eyes and stratified in the three groups by Visual Acuity (VA) at baseline.

    Time frame: at 3±1 months, 6±1months, 12±2 months and at 24±2 months follow-up

  2. Change in Early Treatment Diabetic Retinopathy Study (ETDRS)

    Change Early Treatment Diabetic Retinopathy Study (ETDRS) in all eyes and stratified in the three groups by VA at baseline.

    Time frame: at 3±1 months, 6±1months, 12±2 months and at 24±2 months follow-up

  3. Change in Lasbarhetsindex (LIX, Readability Index)

    Change in LIX in all eyes and stratified in the three groups by VA at baseline. LIX: Jaeger/LIX adult A chart (Ortho-KM, Lund, Sweden). The LIX-chart is a standardized readability index for measuring near vision and it is used almost ubiquitously in eye clinics in Sweden

    Time frame: at 3±1 months, 6±1months, 12±2 months and at 24±2 months follow-up

Secondary outcomes

  1. Proportion of patients with Gain of vision 5 to 15 letters; > 15 letters; Loss of vision >5 to <15 letters; >15 letters or Stable -5 to +5 letters at the annual time points

    Patients with Gain of vision 5-15 letters, \> 15 letters; Loss of vision \>5-\<15 letters; \>15 letters or Stable -5-+5 letters at the annual time points

    Time frame: At year 1 and year 2

  2. Proportion of patients that recuperate 20/20 vision (driving vision) in all patients and stratified by baseline VA (groups 1-3)

    In all patients and stratified by baseline VA (groups 1-3)

    Time frame: Up to 2 years

  3. Proportion of patients that recuperate 20/40 vision (driving vision) in all patients and stratified by baseline VA (groups 1-3)

    In all patients and stratified by baseline VA (groups 1-3)

    Time frame: Up to 2 years

  4. Proportion of patients with no need of Vision Aid support

    Time frame: Up to 2 years
