DIAGNOS Advances Regulatory Strategy with US FDA Submission for CARA System

BROSSARD, Quebec, Sept. 28, 2026 (GLOBE NEWSWIRE) -- Diagnos Inc. (“DIAGNOS” or the “Corporation”) (TSX Venture: ADK, OTCQB: DGNOF, FWB: 4D4A), a Corporation dedicated to the early detection of eye-related health using Artificial Intelligence (AI) techniques, is pleased to announce that it has submitted a Section 513(g) Request for Information to the U.S. Food and Drug Administration (“FDA”) regarding the classification and applicable regulatory requirements for its CARA System.

The submission follows DIAGNOS’ FDA Pre-Submission filing. DIAGNOS filed this submission to address a specific recommendation received from the FDA. This represents another important step in DIAGNOS’ U.S. regulatory and commercial strategy for the CARA System.

CARA System is the logical progression of DIAGNOS’ existing Medical Image Management and Processing System (MIMPS). The new device combines an updated deterministic retinal image enhancement algorithm (CARA-Enhancement), a dedicated Interface for clinician-lead annotations related to retinal conditions, and AI-powered analytic modules that support optometrists in the analysis of retinal images.:

• CARA-AMDdetect – Age-related macular degeneration indicators detection
• CARA-DR – Diabetic retinopathy indicators detection
• CARA-MVA – Retinal microvascular analysis
  

By combining image enhancement, supplementary AI findings, and retinal image and retina microvascular analytics, CARA System helps clinicians unlock more clinically relevant information from every fundus photograph while ensuring that the optometrist remains in full control of every clinical decision.

“This submission represents another milestone in our strategy to bring CARA System to the U.S. market,” said André Larente, President of DIAGNOS. Building on its established license in Canada, for the optometry market, DIAGNOS is pursuing a separate regulatory pathway in the U.S. to access a market of approximately 49,500 optometrists, seeing strong commercial potential in both markets for its AI-assisted solution designed to streamline clinical workflows, ensure diagnostic consistency, and support early detection in everyday optometric practice.
