Optimizing the red reflex
Optimization on the OPMI
For optimum visualization of the red reflex on the OPMI, please check
that:
• the objective lenses are free from contamination,
• the light guide is undamaged and correctly connected,
• the lamp is properly seated in the lamp socket,
• all protection filters have been correctly swung into the beam path,
• the microscope is in the correct working position (the patient's eye
must correspond with the optical axis of the microscope).
Optimization on the monitor
For optimum visualization of the red reflex on the monitor, please make
the following settings:
• Activate the integral light metering function of the camera to reduce re-
flections from the sclera and cornea. (See user manual for the cam-
era.)
Caution:
If the camera adapter is equipped with an iris diaphragm, the latter
should be removed prior to ophthalmic applications. (See user manual
for the camera.)
• Increase the brightness of illumination, if necessary.
