GRF Ambassadors

The GRF Ambassadors are a national leadership group of eye doctors dedicated to improving access to educational materials for all glaucoma patients.

GRF Ambassadors are advocates for patient education, assist with the development of educational materials, and make patient education a key component within their practice.

Educational publications available from Glaucoma Research Foundation include:

  • Understanding And Living With Glaucoma - A comprehensive booklet for patients newly diagnosed with glaucoma - Download in PDF format
  • Childhood Glaucoma - Reference guide for parents and professionals involved in the care of children with glaucoma. - Download in PDF format

The value of patient education can be summarized as:

  • Improved understanding of one's medical condition, diagnosis, and disease
  • Improved understanding of methods and means to manage multiple aspects of glaucoma
  • Improved self-advocacy when working in cooperation with one's doctor
  • Increased Compliance — effective communication and patient education increases patient motivation to comply
  • Patient Outcomes — patients more likely to respond well to their treatment plan with fewer complications
  • Informed Consent — patients feel the doctor has provided the information they need
  • Satisfaction and referrals — patients more likely to stay with the doctor's practice and refer other patients
