Electroretinogram Market Size

The global electroretinogram market size was valued at USD 473.2 million in 2024 and is expected to exhibit growth at a CAGR of 8% from 2025 to 2034 period. The worsening conditions of retinal diseases, such as glaucoma and diabetic retinopathy, along with the growing need for precise early diagnostics, are driving significant growth in the market.

The ERG market is expanding mainly due to the increasing number of retinal disorders like diabetic retinopathy, glaucoma, and age-related macular degeneration. As people around the world grow older, the need for routine retinal check-ups is becoming more important. Health campaigns focused on spreading awareness about eye health have led to a noticeable increase in the use of Electroretinograms (ERGs). This growing acceptance of ERGs is helping ensure that diagnoses are made on time, allowing progressive retinal diseases to be managed more effectively and improving the quality of life for patients dealing with these conditions.
 

Due to the technological advancments in electroretinograms, especially the portable systems, the diagnosis process is comparatively simpler and provide precise results. Battery-operated ERGS make it possible to offer necessary healthcare services in remote areas. Automation in these systems is expected to further enhance the device's operability and diagnosis result.
