Only place in the body where blood vessels can
be visualized directly
Mirror the status of the systemic circulation

Contribute to diagnosis
Direct ophthalmoscopy
Indirect opthalmoscopy
Sterioscopicalview possible
Ideally fundus should be examined
in a darkened room
Patient should be asked to fix their gaze on a
distant object
Examine with corresponding eyes
The ideal line of approach should bring the
optic disc straight in to view
If only blood vessels on a pink background are
seen they should be followed , the disk will
eventually come in to view
