Detailed Description:

Bad response in choroidal neovascularization in High myopia to Photodynamic therapy, which is the current approved treatment for that pathology, and the high incidence of this pathology in these patients, together with the great functional impact in their vision has fostered the search for new therapeutic strategies.

Intravitreal bevacizumab has already been tested in small series of patients with choroidal neovascularization associated to high myopia, whether as first treatment option or after the failure of photodynamic therapy with good results. In the published series an improvement of visual acuity is described after 1-2 injections, with a reduction in the macular edema and a good safety profile.

The lack of published trials that describe the efficacy of frequency of treatment in this pathology is the main reason for this trial.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patient at least 18 years old
  • High Myopia with one of the following:

    • 6 or more sphere diopters in the study eye
    • Axial length of the eye greater than 26 millimeters
  • Active subfoveal/juxtafoveal choroidal neovascularization confirmed by Fluorescein angiography and Ocular coherence tomography.
  • Visual acuity loss of less than 6 months of evolution related to the neovascular lesion, as stated by investigator´s opinion.
  • Patients previously treated with Photodynamic therapy are allowed to participate as long as the last treatment has been performed more than 3 months upon entering the study.
  • Signed informed consent.
  • Signed data protection consent.
  • Women of childbearing potential must provide a negative pregnancy test at inclusion and must commit to the use of a contraceptive treatment during the whole study.

Exclusion Criteria:

  • Previous vitrectomy surgery in the study eye.
  • Tractional maculopathy and/or epiretinal membrane evaluated by Ocular coherence tomography.
  • Opacities that may not allow correct fundus assessment.
  • Lack of integrity of the posterior lens capsule in pseudoaphakic patients.
  • Patients that may not want/be able to complete the study, based in the investigator opinion.
