1. Introduction and Strategic Context

The Global Electroretinogram Market will witness a robust CAGR of 7.2% , valued at $55.1 million in 2024 , and is expected to appreciate and reach $89.1 million by 2030 , confirms Strategic Market Research.

Electroretinograms (ERGs) are diagnostic tests that evaluate the functional health of the retina by measuring its electrical responses to light stimuli. As ophthalmic diagnostics undergo rapid innovation and specialization, ERG systems are playing a strategic role in early-stage detection of retinal disorders such as retinitis pigmentosa , diabetic retinopathy, macular degeneration, and inherited retinal dystrophies.

The strategic relevance of the electroretinogram market from 2024 to 2030 stems from three converging global factors:

• Aging Population & Rising Retinal Disease Burden : The World Health Organization estimates that over 2.2 billion people suffer from vision impairment globally. Age-related macular degeneration (AMD) and diabetic retinopathy—both conditions detectable through ERG—are on the rise in both developed and emerging economies.

• Technological Transformation of Retinal Diagnostics : New-generation ERG devices now offer portable, wireless, and handheld formats. Integration with artificial intelligence (AI) and tele-ophthalmology platforms is transforming these devices from passive diagnostics into active, decision-support tools.

• Regulatory Push & Clinical Research Expansion : Stronger regulatory mandates across North America, Europe, and APAC to improve early diagnosis in ophthalmology clinics and visual function trials are accelerating ERG device procurement.

Key stakeholders in the market include:

• OEMs of ophthalmic diagnostic devices

• Hospitals, ambulatory surgical centers (ASCs), and academic clinics

• Clinical trial organizations conducting vision drug trials

• Governments and public health agencies

• Private investors focusing on medtech and AI-health integration

Electroretinography is no longer confined to specialty vision labs; it is becoming mainstream in community clinics, thanks to portability and protocol simplification. With the global healthcare system pivoting toward early, precise, and non-invasive diagnostics, the ERG market is poised for multi-dimensional expansion.

 

The Electroretinogram (ERG) market is transitioning from a niche electrophysiology tool to a strategic diagnostic platform across retina, neuro-ophthalmology, pediatrics, and clinical trials. The  U.S. Electroretinogram market is around USD 24.6 million in 2024 and is on course to reach the mid-USD 40 million range by 2030 (~10.4% CAGR), while Europe is in the mid-USD 10 millions in 2024 with high-single-digit growth, and APAC is around USD 11.8 million in 2024 and could roughly double by 2030 at ~11.7% CAGR.

 

Underlying disease burden is expanding: an estimated 9.6 million people in the U.S. were living with diabetic retinopathy (DR) in 2021, including 1.84 million with vision-threatening disease. Globally, at least 2.2 billion people have a vision impairment, with approximately 3–4 million cases attributed to diabetic retinopathy and ~10 million to age-related macular degeneration (AMD)

This add-on layer focuses on:

• How full-field ERG (ffERG), pattern ERG (pERG), multifocal ERG (mfERG), and portable ERG platforms are being re-deployed into high-throughput retina clinics, pediatric centers, and clinical trials.

• How contact lens, skin and fiber electrodes are shifting lab workflows toward lower-risk, higher-throughput protocols, especially for post-surgical eyes and DR screening.

• How reimbursement, lab installation and AI-assisted interpretation are evolving in the U.S., Europe, and APAC.

For C-suite leaders, ERG is no longer just a “nice-to-have” lab modality; it has become a functional biomarker platform for DR progression, inherited retinal disease, AMD, drug toxicity, and trial endpoints, with emerging demand for portable and AI-enhanced solutions in all three regions.

• Tele-Ophthalmology Integration : Growing telemedicine adoption creates space for portable, AI-driven ERG devices that can be operated by generalists and reviewed remotely by specialists.

• Expansion into Veterinary and Pediatric Diagnostics : Underserved demographics offer high-growth niches with strong clinical justification and low competitive saturation.

• Regulatory Fast-Track for AI-Aided ERG : AI-assisted diagnostics are gaining favorable FDA and CE review pathways, accelerating market entry for next-gen systems.

 

Restraints

• High Initial Capital Cost : Advanced ERG systems with multimodal capabilities are priced beyond the reach of smaller clinics in low- and middle-income countries.

• Shortage of Trained Ophthalmic Electrophysiologists : Interpretation of advanced ERG formats still requires specialized training, limiting widespread deployment despite technological simplification.
