Specifically, the VesselMap2 software is intended to be used for semiautomated measurement and calculation of the retinal artery/vein diameter ratio. ## Device Story Static Vessel Analyzer (SVA) captures, displays, stores, and manipulates retinal images; utilizes fundus camera and digital image sensor. SVA software comprises VisualIS (imaging management) and VesselMap2 (analysis add-on). User selects veins and arteries on images; software estimates vessel diameters and calculates arterial-venous ratio. Used in clinical settings by healthcare providers to aid in diagnosis or monitoring of eye diseases. Semi-automated measurement improves repeatability and reduces reader-to-reader bias compared to manual methods. Output assists clinicians in assessing retinal vascular health. ## Clinical Evidence Method comparison study (bench testing) compared VesselMap2 semi-automated analysis to manual methods. Results demonstrated agreement between methods, smaller intra- and intergrader variability for the semi-automated method, and elimination of systematic reader-to-reader bias observed in manual analysis. Appropriate intravisit and intervisit reproducibility confirmed. ## Technological Characteristics Fundus imaging system; includes digital image sensor. Software components: VisualIS (image management) and VesselMap2 (semi-automated analysis). Connectivity: standalone or integrated with fundus camera. Software algorithm: semi-automated vessel diameter estimation and ratio calculation. ## Regulatory Identification An ophthalmic camera is an AC-powered device intended to take photographs of the eye and the surrounding area. ## Special Controls *Classification.* Class II (special controls). The device, when it is a photorefractor or a general-use ophthalmic camera, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 886.9. ## Predicate Devices - Carl Zeiss FF450plus VISUPAC System ([K011877](/device/K011877.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Specifically, the VesselMap2 software is intended to be used for semiautomated measurement and calculation of the retinal artery/vein diameter ratio. \\\DC - 033404/000001 - 2909663 v1 {1}------------------------------------------------ ## Technological Characteristics: The IMEDOS SVA unit is designed as a complete Fundus Imaging system or the software can be sold separately as a standalone product. The SVA software consist of two components - VisualIS, an imaging software for capture, display, storage and manipulation of images of the eye and VesselMap2, an add-on for enhanced analysis of retina images. VisualIS captures the images which are provided by the fundus camera and the connected digital image sensor. Together with an image set the data of the patient are recorded and stored. The complete examination can be stored and opened for follow-up examination purposes. The add-on VesselMap2 offers a semi-automated measurement for Arterial -- Venous Ratio of retinal vessels. The software allows the user to select veins and arteries. Vessel diameters are estimated by the software and the ratio of the analyzed arteries to veins is calculated. The image is not altered in any way during this calculation. The manual and semi-automatic calculation were compared and verified on representative retina images and the results show improved repeatability of the semi-automated calculations based on the uncertainty and precision of manual vessel diameter determination based on the user's subjective perception of vessel edges. ## Performance Data Imedos completed a comprehensive method comparison study assessing the VesselMap software function compared to an accepted, manual method for determining arterial-venous ratios. This study assessed agreement, reproducibility, and repeatability. The completed study demonstrated: - 1. Agreement between manual and semi-automatic (VesselMap2) retinal vessel analysis, without any indication of statistically significant differences between methods; - 2. Smaller intragrader variability) and intergrader variability (reproducibility) for the semi-automatic method (VesselMap2) than for the manual method; - 3. In the manual method, a systematic bias between the two graders exists, which is not the case in the semi-automatic method. Thus, the comparison study demonstrated that the VesselMap software does not introduce reader-to-reader bias; - 4. Appropriate intravisit and intervisit reproducibility for the semi-automatic method. The visit-tovisit variability (whether for manual or semi-automated analysis) was shown to be much higher than the variability in results associated with the device. ## Substantial Equivalence The Imedos SVA System has the same intended use, principles of operation and technological characteristics as the Carl Zeiss FF450plus VISUPAC System (K011877). The minor differences between the Carl Zeiss FF450plus VISUPAC System and the Imedos SVA system do not raise new questions of safety or effectiveness. Performance data demonstrate that the SVA System is as safe and effective its predicates. Thus, the SVA System is substantially equivalent. {2}------------------------------------------------ #### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
