 Glaucoma specialists have the training and expertise to medically and surgically treat all types of glaucoma—common, advanced, rare, and complex. Eye care providers should consider referring a patient to a glaucoma specialist when:

- Available diagnostic resources are limited
- The patient is taking multiple medications
- The patient is not responding to treatment
- The disease is progressing, despite normal IOP
