Some arguments presented for using the spot retinoscope are:
1. When working with pediatric patients, it is important to get the
most information in the shortest amount of time. The spot scope,
based on the shape of the reflex, can help detect astigmatism very
quickly. Also significant amounts of myopia and hyperopia can be
determined rapidly.
2. For vision screening a large number of patients, e.g. school
screenings, the spot retinoscope can help provide more
information in a shorter period of time.
3. For judging the fit of hard contact lenses the spot scope can be
helpful in assessing power correction, centration, tear film layer,
etc.; and to check soft lenses for indications of buckling, lens
transparency, and steep or flat corneal correspondence.
To convert the No. 18200 streak retinoscope to a spot
retinoscope, simply insert the No. 08300 lamp (see directions
on page 12). The spot retinoscope is used in the plano mirror
position (sleeve all the way down).
