Further study details as provided by Maastricht University Medical Center:

Primary Outcome Measures:
  • IOP levels, including IOP peaks occurring during or directly after playing, and prevalence of glaucomatous field loss in players of wind instruments. [ Time Frame: One hour. ] [ Designated as safety issue: No ]
  • IOP peaks and variations during continuous IOP monitoring [ Time Frame: 24 hours ] [ Designated as safety issue: No ]
    Several high-risk participants will be asked their permission to perform continuous IOP monitoring during 24 hours with a sensing contact lens.

Secondary Outcome Measures:
  • Risk factors for glaucoma and the prevalence of visual problems and eye disease among (professional) musicians [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Participants of orchestras will be asked to fill in a questionnaire to collect demographic data together with data on musical history,ophthalmologic history and family history on glaucoma and ocular hypertension. From these participants, a selection will be invited for further screening.
