title: The treatment of choroidal neovascularizations in age-related macular degeneration using either Avastin or Lucentis.
abstract: BACKGROUND
  Either Avastin or Lucentis was used in our clinic to treat choroidal neovascularizations in age-related macular degeneration. The number of injections necessary for drying the macular findings was especially assessed.
  
  
  METHODS
  From April 2006 to August 2008 324 eyes were treated with Avastin, and from January 2007 to August 2008 348 eyes were treated with Lucentis. The intravitreal injections with Avastin (1.25 mg in 0.05 mL) were performed every six weeks, and with Lucentis (0.05 mg in 0.05 mL) every four weeks until the macular findings were considered to be dry. Fluorescein angiography and optical coherence tomography were used for the diagnosis and for the checks which were carried out every twelve weeks. The visual acuity was measured with an ETDRS chart.
  
  
  RESULTS
  The treatment with Avastin is completed in 319 eyes with an average improvement of the visual acuity of 5.1 letters after 3.3 injections, and with Lucentis in 226 eyes with an average improvement of the visual acuity of 6.4 letters after 3.4 injections (p = 0.24; one way ANOVA).
  
  
  CONCLUSIONS
  Both of the drugs allow the drying of the macular findings in the great majority of the cases after a short time and lead to a quite similar improvement of the visual acuity. A definitive stabilization of the disease after stopping the treatment is not foreseeable.
