optomap® Retinal Exam
a closer look at our products
The Company’s core product is the optomap® Retinal Exam,
which is produced by the P200 device and is used in primary
level eyecare for the screening of eye and non-eye diseases
and disorders. optomap® plus Medical Retinal Exam is also
performed using the P200 and is used in secondary level care,
using additional capabilities in the image capture and review
process to facilitate diagnosis and documentation of previously
detected pathology. optomap® fa Medical Procedure offers
retinal specialists advanced diagnostic, monitoring and treatment
capabilities for particular eye disorders, including diabetic
retinopathy and age-related macular degeneration.
Our USP
Examination of the retina forms
part of a comprehensive eye
examination. In capturing 200
degrees or approximately 82% of
the retina in a single capture, Optos
believes that its technology plays a
leading role in assisting with the early
detection and diagnosis of both eye
and non-eye diseases, in tracking
and monitoring the development of
diseases and optimising treatment
plans through ongoing evaluation.
This enables healthcare practitioners
to deliver a higher standard of care
to their patients, improve patient
outcomes and ensure that the
patient’s experience of having a
retinal examination is positive and
educational.

Technology
The patented scanning laser system
developed by Optos generates
a digital wide-field (200 degree
internal angle) image of the retina.
Optos’ P200 device uses this unique
imaging system to create a ‘virtual
scanning point’ inside the patient’s
eye, and has the following features
which are not offered in their entirety
by conventional methods of retinal
examination:
• wide-field – approximately 82%
of the patient’s retina is captured
in a single image;
• rapid image capture – image capture
takes a quarter of a second once the
patient is positioned relative to the
device;
• dilation not necessary – the device
is designed to be able to take an
image through a 2mm aperture, and
therefore the decision to dilate is one
taken by the practitioner as opposed
to a necessity mandated by the
instrument requirements; and
• unaffected by most cataracts
– the P200 device employs two
independent low-power laser
sources which operate at discrete
wavelengths and are diffracted less
than white light, thereby enabling
more successful imaging through
cataracts than with white light,
which tends to scatter when it tries
to penetrate the cataract.
The scanning laser system combines
the two low-powered lasers into a
single beam that is then projected
onto the patient’s retina and
manipulated through a 200-degree
scan angle. Light reflected from the
retina is then returned through the
scanning system and is converted to
electrical impulses by highly sensitive
photo-diodes. These impulses are in
turn digitised and formatted to create
the image.
The scanning laser system is managed
by Optos’ proprietary software
application suite. Optos has developed
‘‘Capture Software’’ which enables
the operation of the P200, including
the facilitation of patient imaging.
