I am a firm believer that playing a brass instrument such as a trumpet leads to increased eye pressure causing glaucoma. I played a trumpet for 6 years when I was young. When I was 32, I was diagnosed with glaucoma. Opthamalogists have told me that glaucoma is hereditary and poo-pooed my belief; however, no one in my family has or had the disease; therefore, I conclude that my glaucoma was caused by playing the trumpet. Thank you.
