Comparing Rates of Glaucomatous Optic Neuropathy in Professional Wind Versus Non-wind Instrument Players in the Philadelphia Orchestra
The purpose of the present study is to compare rates of glaucomatous optic neuropathy in
professional wind versus non-wind instrument players in the Philadelphia Orchestra. A
secondary objective is to evaluate intra-ocular pressure and choroidal thickness of wind
instrument players under variable playing conditions.
professional wind versus non-wind instrument players in the Philadelphia Orchestra. A
secondary objective is to evaluate intra-ocular pressure and choroidal thickness of wind
instrument players under variable playing conditions.
Participants of this study will be any current or retired member of the Philadelphia
Orchestra. Approximately 100 participants will be divided into 2 groups: 1) wind instrument
players and 2) non-wind instrument players.
A wind instrument is defined as any instrument that contains a resonator, in which a column
of air is set into resonation by the player blowing into a mouthpiece at one end of the
resonator. A non-wind instrument is defined as any instrument that does not meet the wind
instrument criteria.
On the day of the eye examinations, the investigator will provide a brief overview to
explain the purpose and goals of the study to all potential participants. The examination
team will be set up in an adjoining room. Members of the orchestra will be able to visit the
examination team at any time during their practice session. A trained technician will
perform the following for both eyes for all participants:visual acuity,undilated fundus
color photography and intra-ocular pressure measurement. The investigators will record the
examination findings using a standard form. Demographic information, including ocular,
medical, social, and family history, will be documented for all participants.
