How does the Coaxial Vision System of the conventional ophthalmoscope help when performing a fundus exam?
When viewing the fundus it is extremely important that the light beam from the ophthalmoscope and your viewing angle area are in close proximity. The path your eye follows through the patient’s eye to the fundus is extremely narrow; therefore, the most efficient method of viewing the fundus is to keep the ophthalmoscope’s light beam and your vision line in synch as much as possible.
