2.6.3 Image modalities
Optos multi-modal ultra-widefield retinal imaging enables the capture of posterior images, with a field of view
of up to 200 degrees in a single capture, and in an imaging time of less than 0.4 seconds.
Depending on the configuration of your device the following image modalities may be available:
optomap
optomap is an ultra-widefield
optomap combines sensory and choroidal reflectance images and provides UWF image views from a single
capture action:
optomap color view – an UWF color fundus image combining red and green reflectance images.
l
optomap neurosensory view – an UWF green laser reflectance image of the surface retina.
l
optomap choroidal view – an UWF red laser reflectance image of the deeper retina.

is typically used for healthy eye exams or screening applications.
2.6.4 System software
The system contains features to help you configure the system and to capture, review, archive and retrieve
images. The system software comprises:
Scan head software that enables capture of patient studies.
l
Image server 'middleware' that encodes patient studies for storage.
l
Image server 'archive and review' software provided by OptosAdvance.
l
Browser-based review clients.
l
The image capture software runs on the scan head.
2.6.4.1 Understanding the review software
OptosAdvance
is browser-based review software that runs on the image server. It enables eye care
professionals to manage and display the following data and images:
