Macular edema

A study to assess the effectiveness of aflibercept in routine clinical practice in patients with diabetic macular oedema

Trial purpose

Intravitreal aflibercept has been approved for the treatment of visual impairments due to diabetic macular oedema (DMO) in Europe and the US in August 2014 and July 2014 respectively.
The main objectives of this observational cohort field study are to evaluate effectiveness of intravitreal aflibercept and to describe follow-up as well as treatment patterns in anti vascular endothelial growth factor (anti-VEGF) treatment naïve patients with DMO in routine clinical practice in the United Kingdom.

Primary Outcome

  • Change in Best Corrected Visual Acuity (BCVA) in Early Treatment Diabetic Retinopathy Study (ETDRS) letters in patients with DMO treated with intravitreal aflibercept
    BCVA (Best Corrected Visual Acuity): process to measure with the help of a retinoscope, auto-refractor or phoropter how much power is needed to bring the eye to normal, perfectly focused vision) when performed in addition to that at baseline and 12 months. ETDRS Chart: charts imprinted with lines of letters decreasing in size from largest on top to smallest on the bottom to determine visual acuity.
