3.2.5 Examination
WARNING
Do not illuminate the patient’s eye for more than 1 minute per eye and be sure
to keep illumination at minimal intensity needed to view the fundus.
(1) Holding an aspherical lens in one hand, direct the illumination into the patient eye. It
is recommended to place the unoccupied fingers of the hand holding the aspherical
lens on the patient’s face for stability.
(2) Bring the aspherical lens close to the patient eye and gradually move away from the
eye until a clear image of the fundus is obtained.
*Note: The distance between the patient eye and aspherical lens is dependent on
the optical power (diopter, 1 D = 1 / focal distance in meters) of the aspherical
lens.
Optical Power Description of Image
14 D to 16 D High magnification, bright image, narrow field of view
20 D Typically used in standard examinations
28 D to 30 D Low magnification, dim image, wide field of view
The illumination system and observation system can be configurated as follows to
optimize examination
<Examining Large Pupils>
When examining the fundus through large pupils,
raise both the IlluminationAngle Adjustment Lever
and Observation Angle Adjustment Lever. The
illumination axis and observation axes are
distanced, allowing for better stereoscopic vision
with reduced glare (see Fig. 3.9a).

<Examining Small Pupils>
When examining the fundus through small pupils,
lower both the IlluminationAngle Adjustment Lever
and Observation Angle Adjustment Lever. The
illumination axis and observation axes come closer,
allowing for easier concentration of light into the pupil
(see Fig. 3.9b).
<Examining Horizontally Elliptical Pupils>
When examining the fundus through horizontally
elliptical pupils, lower the IlluminationAngle
Adjustment Lever and raise the Observation Angle
Adjustment Lever. The illumination axis will come
closer the observation axes while the observation
axes remain apart (see Fig. 3.9c).
<Examining Vertically Elliptical Pupils>
When examining the fundus through vertically
elliptical pupils, raise the IlluminationAngle
Adjustment Lever and lower the ObservationAngle
Adjustment Lever. The illumination axis will remain
apart while the observation axes come closer (see
Fig. 3.9d).
