that has a growing light crescent on a board. Such growing light should be
considered an artifact and not a feature of the retina under examination.
 Do not leave the front lens uncovered while the system is not in use.
Note on auto-alignment:
The auto-alignment process may fail in some circumstances such as:
 long eye-lashes;
 presence of make-up;
 room too bright;
 direct light on a patient’s face;
 very big pupil.
Under such circumstances the exam should be repeated after removing the cause of
the failure.
8. NOTES TO OPERATOR
No specific skills are required to operate the DRS.
A minimal, device specific, training is required to become able to use the system.
The operator needs to be acquainted with the following concepts:
 pupil: the central part of the external surface of the eye, through which light goes in;
 retina: the internal surface of the eye ball;
 fixation / fixating: the ability of a subject to stare at a specific point in space and specifically
the DRS internal fixation targets.
