Material and Methods: A prospective survey study with a face-to-face interview technique was organized. Participants were grouped as healthcare workers (group 1) in a training and research hospital (TRH), patients admitting to a TRH (group 2), and patients referred to our district polyclinic (group 3). Seven questions were asked about the knowledge level.

Results: There were 416 valid contributions of the participants, 113 were in group 1, 138 in group 2, and 165 in group 3 (27.2%, 33.2%, and 39.7%, respectively). 112 participants (99.1%) in group 1, 89 participants (64.5%) in group 2, and 94 participants (57%) in group 3 answered ?yes? to the question about awareness of glaucoma. There was a signifi cant difference between the groups (p = 0.00). There was no signifi cant difference between the levels of awareness in groups 2 and 3 (p = 0. 18,95% CI, OR = 1.375). For groups 2 and 3, family members, television, and close acquaintances were important sources of awareness (? 20% for both groups). Glaucoma knowledge was different among the three groups (p = 0.002). Groups 2 and 3 differed in terms of knowledge levels (p = 0.009).

Conclusion: Healthcare workers\' glaucoma awareness and knowledge levels are good. We believe that awareness of glaucoma would increase with more effective use of mass media and healthcare workers. Keywords : Glaucoma, Healthcare worker, Awareness of glaucoma, Knowledge of glaucoma, Public health
