Anatomy of an Ophthalmoscope

Ophthalmoscopes are used for examining the interior of the eye. They can help to diagnose: damage to your optic nerve, retinal tear or detachment, glaucoma, macular degeneration, cytomegalovirus (CMV) retinitis, melanoma, hypertension, and many more. Riester offers two tiers of ophthalmoscopes, our economic e-scope pocket version as well as the premium traditional style instrument.
