Electroretinography Market

Global Electroretinography Market Size

The size of the global electroretinography market was worth USD 5.85 billion in 2025. The global market is anticipated to grow at a CAGR of 8.4% from 2026 to 2034 and be worth USD 12.09 billion by 2034 from USD 6.34 billion in 2026.

Electroretinography is the study of electrical impulses sent by the retina in response to light. Electroretinogram is an eye test that tries to detect abnormalities in the functioning of the retina. The retina is the innermost light-sensitive layer of cells that translates images into electrical impulses for the brain to create visual perception. The retina comprises many layers of cells with varied functionalities and purposes that coordinate to make image recognition possible. There are photoreceptor cells (rods and cones) that detect light and transmit signals to intermediary cells (Muller cells and bipolar cells). Finally, the Ganglion cells transmit the impulses that are recorded by the brain as images. In this test, an electrode in the form of a thin wire or a contact lens is placed on the cornea (front part) of the eye after dilating the patient's eyes and anesthetizing him/her. This electrode will register the electrical impulses while the eyes are subjected to various image and light inputs. It will help the physicians calibrate the retinal defect's exact nature and prescribe the appropriate course of action.

MARKET DRIVERS

There is general growth in the medical and healthcare sector due to the increasing levels worldwide. Developed nations like Japan, Germany, Italy, Finland, and other European countries have an increasingly older demographic. Due to this population reason, many of these nations have resorted to importing younger people from less developed nations to balance the lack of taxpayers. This simultaneous rise in population due to immigration and an increase in the elderly population in these nations is expected to drive the healthcare sector and the electroretinography market. With the rapid industrialization and urbanization of many Asian economies, several people have jobs paying much more than they did a few decades ago. This increase in income has contributed to people being able to access better healthcare facilities for themselves and their loved ones. With China's one-child policy, many young Chinese families have four parents and eight grandparents to take care of. With increased health complications due to old age, the Electroretinography market seems very promising in China. Countries like India, Malaysia, Indonesia, Taiwan, and Australia are also anticipated to be key markets for electroretinography due to their burgeoning economies and growing populations.

MARKET RESTRAINTS

However, many people worldwide are still stuck in abject poverty and cannot afford quality healthcare. Prohibitive pricing of diagnostic testing in many countries hurts the market by access to wealthier patients. Lack of awareness among people and the inability to afford treatment are two main factors restraining the growth of the global electroretinography market.

SEGMENTAL ANALYSIS

By Product Type Insights

Based on product type, the Fixed ERG machines segment offers a full range of functionality in exchange for ease of movement and portability. These machines are suitable for large multi-specialty and single-specialty hospitals that can attract a large number of patients. Portable EGR machines are easy to carry and can be transported with an ease that is not possible with fixed machines. However, most portable machines are not as good as fixed alternatives and have reduced functionality. These are most suitable for clinics and mobile hospitals that operate in regions that lack permanent infrastructure facilities. Since both machines have different clientele, they have steady markets with healthy growth rates.

By End Use Insights

While machines are mostly used on humans in Clinical medicine, the research sector uses multiple animal species to understand the structure eye and develop new techniques and procedures. The machines used in research, as a result, are also quite different from their clinical brethren. Primates, Rodents, and other small animals are routinely used in laboratories for research purposes.

REGIONAL ANALYSIS

Geographically, the North America and Europe regions are currently the largest markets for electroretinography; with the rising population levels and decreasing unemployment in these regions, the market has a bright future. Among all those regions, the North American market contributes the largest share with a high compound annual growth rate across the globe in the electroretinography market by owning many advantageous factors such as technological advancement. By following the North American region, the European area is recorded as the second-largest revenue growth share region by owning many factors like the development of facilities. As expected during the forecast period, the Asia-Pacific region contributes a high and fast compound annual growth rate due to developing countries such as Japan, China, and India. The Middle East and Africa region are contributing to the smallest revenue growth share.

The region of Asia Pacific is anticipated to grow with the highest CAGR during the upcoming years. It can be attributed to the region’s large population and growing economy.

GLOBAL ELECTRORETINOGRAPHY MARKET NEWS

• Scientists from Peking University, Beijing, created a soft Graphene Contact lens Electrode (GRACEs) that addressed patient discomfort due to rigid electrodes, limited types of electroretinograms with a single type of electrode, reduced signal amplitudes and stability, and excessive eye movement. They made sure that the lens did not have any wrinkles by growing it on curved quartz molds.
• Pattern Electroretinography was a handy tool for evaluating patients with early-stage Glaucoma, particularly Glaucoma suspects. According to the latest article published by the authors Porciatti and Ventura in Current Ophthalmology Reports, the Pattern Electroretinography of the patients at risk of progression from suspected to manifest glaucoma reveals alterations in signal even before they start to lose visual field and optic nerve tissue.
• A new technique invented by a team of researchers from the University of Bradford, UK, led by Dr. Declan McKeefry, was able to 'silence' the L- and M-cones and the rods so only the signals from the S-cones are picked up by using stimuli at different wavelengths. This novel method addresses the shortcomings of the usual Electroretinography method that cannot distinguish between the different types of cones. Machines that integrate this facility can break ground into a virgin market.
