Those at high risk for ophthalmic disorders:
Screen every 2 years. Schedule exam by an ophthalmologist shortly after a high-risk factor has been identified.
- Aged over 65 years
- Past retinal detachment
- Past serious ocular trauma
- Persistent visual loss
- Sickle cell disease
- Family history of glaucoma
- Other heritable ocular disease
Those at low risk for ophthalmic disorders:
You do not need to screen for glaucoma by performing tonometry. Why not? Because a single tonometric reading can be misleading. Assessment of optic disc cupping is much more meaningful.
- Ages 6 to 40: screen for visual acuity every 3 years. Refer to an ophthalmologist if you find an abnormality.
- Ages 40 to 65: do complete exam every 2 years. Schedule exam by ophthalmologist every 4 years to monitor for glaucoma and to provide optical correction for presbyopia.
