The Eye

In addition to examination of the fundus, the PanOptic
Ophthalmoscope is a useful diagnostic aid in studying other ocular
structures. The light beam can be used to illuminate the cornea and
the iris for detecting foreign bodies in the cornea and irregularities of
the pupil.

The practitioner can also easily detect lens opacities by looking at the
pupil through an add-on corneal viewing lens. In the same manner,
vitreous opacities can be detected by having the patient look up and
down, to the right and to the left. Any vitreous opacities will be seen
moving across the pupillary area as the eye changes position or comes
back to the primary position.
