Portable ERG and AI-aided analysis software lack established payment categories in several Asia-Pacific countries, shelving purchasing decisions despite clinical need. Harmonization efforts led by ISCEV and regional ophthalmic societies are underway, yet a uniform pathway remains years away, tempering near-term electroretinogram market acceleration.

Segment Analysis

By Device Design: Portable Platforms Stretch the Care Continuum

Fixed stations accounted for 62.34% of the electroretinogram market in 2024, reflecting their legacy base in tertiary referral hospitals where comprehensive electrophysiology labs remain essential for rare-disease workups. Most models integrate dark-adaptation chambers, pattern stimulators, and multifocal modules, allowing ophthalmologists to switch modalities without swapping hardware. However, portable devices are scaling at a 10.45% CAGR because rural clinics and primary-care offices prize weight, footprint, and battery operation over full modality suites. The RETeval handheld unit links to cloud dashboards via Bluetooth, capturing cone response flicker under photopic conditions and auto-grading severity within seconds. This convergence of portability and analytics elevates portable systems from triage tools to frontline diagnostic assets. Looking ahead, hybrid architectures—soft multi-electrode lenses tethered to smartphone apps—promise to fuse the signal quality of fixed equipment with the reach of handhelds. Such versatility blurs traditional segmentation lines, reshaping the electroretinogram market trajectory through 2030.
