Current Primary Outcome Measures
 (submitted: February 28, 2017)
Change in retinal morphology by SD-OCT [ Time Frame: Baseline, first year, 2nd year, 3rd year ]
To exploratively determine the pathogenesis within the project population by assessing and evaluating the risk factors of myopic CNV by measuring the change in retinal morphology with spectral domain optical coherence tomography (SD-OCT). Risk factors are defined as choroidal thinning < 50μm, choroidal curvature length > 6300 μm (nasal temporal), lacquer cracks, patchy atrophy > 5mm² and preexisting myopic CNV in second eye.
Original Primary Outcome Measures Same as current
Change History
Current Secondary Outcome Measures
 (submitted: February 28, 2017)
  • Change in retinal morphology by fundus autofluorescence [ Time Frame: Baseline, first year, 2nd year, 3rd year ]
    To exploratively determine the pathogenesis within the project population by assessing and evaluating the risk factors of myopic CNV within the project population by measuring the change in retinal morphology with fundus autofluorescence. Risk factors are defined as choroidal thinning < 50μm, choroidal curvature length > 6300 μm (nasal temporal), lacquer cracks, patchy atrophy > 5mm² and preexisting myopic CNV in second eye.
  • Change in retinal morphology by fundus photography [ Time Frame: Baseline, first year, 2nd year, 3rd year ]
    To exploratively determine the pathogenesis within the project population by assessing and evaluating the risk factors of myopic CNV within the project population by measuring the change in retinal morphology with fundus photography. Risk factors are defined as choroidal thinning < 50μm, choroidal curvature length > 6300 μm (nasal temporal), lacquer cracks, patchy atrophy > 5mm² and preexisting myopic CNV in second eye.
  • Change in Best Corrected Visual Acuity (BCVA) by vision testing (Landolt chart or equivalent) [ Time Frame: Baseline, 3rd year ]
    To exploratively determine the pathogenesis within the project population and within the individual patient by change of BCVA from baseline to 3rd year.
  • Change in refraction error by autorefractometer [ Time Frame: Baseline, 3rd year ]
    To exploratively determine the pathogenesis within the project population and within the individual patient by change of refraction error from baseline to 3rd year.
Original Secondary Outcome Measures Same as current
Current Other Pre-specified Outcome Measures
 (submitted: February 28, 2017)
  • Occurence of myopic CNV at the investigator's discretion [ Time Frame: From baseline until the date of occurence of myopic CNV at the investigator's discretion (if any), assessed up to 3 years. ]
    To assess if myopic CNV in study eye and/or fellow eye occured from baseline to 3rd year.
  • Change in health related quality of life (QoL) by NEI-VFQ-25 questionnaire [ Time Frame: Baseline and 3rd year (or at the date of occurence of myopic CNV at the investigator's discretion, if any, whichever comes first, assessed up to 3 years). ]
    To assess the change in health related QoL by patient reported outcome with the VFQ-25 questionnaire.
  • Assessment of biomarkers by analyzing blood samples [ Time Frame: Baseline and at the date of occurence of myopic CNV at the investigator's discretion, if any, assessed up to 3 years. ]
    To assess biomarkers which are possibly related to mCNV development. Blood samples will be taken at baseline from all patients who gave separate informed consents. A second sample will only be taken at CNV occurence (if any), assessed up to 3 years. Inflammatory and angiogenic markers will be measured and checked for the potential association to CNV formation.
  • Assessment of genetic factors by analyzing blood samples [ Time Frame: Baseline and at the date of occurence of myopic CNV at the investigator's discretion, if any, assessed up to 3 years. ]
    To assess genetic factors which are possibly related to mCNV development. Blood samples will be taken at baseline from all patients who gave separate informed consents. A second sample will only be taken at CNV occurence (if any), assessed up to 3 years. Inflammatory and angiogenic markers will be measured and checked for the potential association to CNV formation.
  • Change in axial length of the bulbus by optical biometry [ Time Frame: Baseline, first year, 2nd year, 3rd year ]
    To assess the change in axial length of the bulbus in both eyes by optical biometry.

Eligibility Criteria

Inclusion Criteria:

  • Male or female caucasian patients ≥ 18 years of age
  • Diagnosis of high myopia secondary to an anterior-posterior elongation of the bulbus confirmed by ocular examination in either eye using the following criteria:

    • Ocular ultrasonography or biometry demonstrating anterior-posterior elongation measurement ≥ 26 mm
    • abnormal change in retinal tissue by SD-OCT that are attributed to be caused by high myopia as shown in Table 4-2 of the protocol in the investigator's discretion confirmed by the reading centre

Exclusion Criteria:

  • Patients with Diabetes mellitus of any grade
  • Patients showing signs of Age-Related Macular Degeneration (AMD), e.g. drusen, characteristic changes in fundus (with shaping or extension of hemorrhages, fibrosis, exudative areas) in either eye
  • Acute neovascularization (CNV or iris neovascularization) and intra- or subretinal fluid in either eye at the time of enrolment.
  • History of inactive CNV in study eye. Inactive CNV of fellow eye is allowed if treatment was performed more than 12 months before enrolment.
  • Any anti vascular endothelial growth factor' (anti-VEGF) or Verteporfin treatment in study eye and anti-VEGF or Verteporfin treatment less than 12 months before enrolment in fellow eye
  • History of systemic anti vascular endothelial growth factor' (anti-VEGF) therapy
  • Cataract that would prevent an accurate measurement of the axial length of the study eye
