How to guide the observation light to the examined eye in mydriatic photography.
In fundus photography, it is necessary to guide sufficient exposure which comes to the fundus through the
pupil. Therefore, the camera position that will satisfy this lighting condition to the examined eye is very re-
stricted. Flashlight travels on the same path as observation light. So if you can observe the fundus under a
uniform illumination without flare or reflections (correct camera position for incidence), you are sure to get
good fundus photographs.
a) While looking into the cornea of the examined eye directly from the side of objective lens, move the
base longitudinally and laterally with the control lever upright such that a rough image of illumination
ring-slit focused on the cornea of the examined eye can be obtained.
b) Adjust vertical positioning of the camera by turning the camera height adjusting handle.
c) Then while looking into the viewfinder, adjust alignment and guide the observation light into the fundus.
