DEVICE DESCRIPTION
RetinaLyze System is a cloud based retinal investigation medical software, which functions as a Clinical Decision Support Tool for Eye Care Professionals to investigate the pathological changes in the retina and optic nerve head.
The device is a web application allowing operators to interact with the different sub-systems like RetinaLyze DR, RetinaLyze AMD, RetinaLyze Glaucoma and Eye Specialist Backup (ESB) Module.
The device analyses fundus images and the results are displayed as an annotated overlay photos together with a colorized descriptive text.
RetinaLyze DR and AMD create an overlay photo that marks the position of the changes, found by the algorithm whereas RetinaLyze Glaucoma creates an overlay photo on the optic nerve head (ONH) showing the measured level of hemoglobin.
The Eye Specialist Backup module (ESB) sends a fundus photo of an eye to an ophthalmologist who examines the photo and send a response directly in RetinaLyze System.

This population include patients having a complete assessment of their vision and general eye health at Hospitals, Specialist clinics or at Local Optometrists Primary Eye Care services.
WARNINGS
Do not use the software for the investigation of the retinal images with bad image quality, as the patient can be given a false negative or false positive results.
CAUTIONS
The information provided by RetinaLyze System device do not replace a consultation with an Eye Care Professional to determine the further diagnosis options and therapies based on the patient history, and patient characteristics as a part of complete assessment of patients vision and general eye health in both retail and clinical settings.
The interpretation of assigned lesions on fundus images for people up to 40 years of age should be carefully assessed due to reflection in the membrana limitans posterior as they might be falsely interpretated as white lesions or blood vessels as dark lesions.
The interpretation of fundus images for patients who have been diagnosed with or treated for retinal eye-diseases should be carefully assessed, as the patient can be given a false negative or false positive result.
CLINICAL BENEFIT
Investigation and identification of minor white and black lesions and presence of hemoglobin in the Optic Nerve Head.
The device performs consistent retinal investigation and delivers a uniform result based on the retinal fundus image of the eye.

Data Security
RetinaLyze system have implemented technical and organizational measures to ensure an appropriate level of security, taking into account the nature, scope, context, and purpose of the processing, and the risks to protect against unauthorized or unlawful processing of Personal Data and against accidental loss or destruction of, or damage to, Personal Data, appropriate to the harm that might result from the unauthorized or unlawful processing or accidental loss, destruction or damage and the nature of the data to be protected, having regard to the state of technological development and the cost of implementing any measures.
Those measures will include, where appropriate, pseudonymizing and encrypting Personal Data, ensuring confidentiality, integrity, availability and resilience of its systems and services, ensuring that availability of and access to Personal Data can be restored in a timely manner after an incident, and regularly assessing and evaluating the effectiveness of the technical and organizational measures adopted by it.
Security measures
The servers for the online application, databases, and data protection (backup) are run and maintained by third parties in professional data centers. Subcontractors are selected carefully and with respect to their security awareness and their expertise based on verified audits and certificates. Some of the relevant safeguards of the following checklist are not shown separately because it is the responsibility of subcontractors or are not published in detail for the sake of maintaining the security of confidentiality.
Access control (Physical)
The access control to the server infrastructure occurs by the spatial structure of the data centre and there through the operator ensured control system. Physical access to the servers is maintained and controlled by subcontractor.
Access control (Logical)
RetinaLyze System has implemented suitable measures to prevent its data processing systems from being used by unauthorized persons.
This is accomplished by:
Automatic lock out of the user ID when several erroneous passwords are entered. Events are logged and logs are reviewed on a regular basis.
Automatic time-out of user terminal if left idle, identification and password required to reopen.
Continuously monitoring infrastructure security.
Regularly examining security risks by internal employees.
Role-based access control implemented in a manner consistent with principle of least privilege.
Remote access to infrastructure is encrypted and secured using two-factor authentication tokens.
Access to host servers, applications, databases, routers, switches, etc., is logged.
Passwords must adhere to the RetinaLyze System password policy, which includes minimum length requirements and enforcing complexity.
Transmission control
RetinaLyze System has implemented suitable measures to prevent Personal Data from being read, copied, altered or deleted by unauthorized parties during the transmission thereof or during the transport of the data media.
