Crude prevalenceofvision loss due to diabetic retinopathy, Global, South Asia, North Africa and Middle East, 2020
(all ages, males & females)
Source: Data from VLEG/GBD 2020 model, accessed via the IAPB Vision Atlas
Cause data is not available for people with mild vision impairment.
Also, there is limited information on the causes of vision impairment and blindness for people under 50 years of age.
More standardisation and certainty of the causes of vision impairment and blindness would be beneficial in future research.
Diabetic Retinopathy: Global summary from the VLEG study
Diabetic retinopathy is the smallest contributor to vision loss amongst listed causes in 2020. However, it is the only cause of blindness that showed a global increase in age-standardised prevalence between 1990 and 2020. This is likely due to an increase in the prevalence of diabetes and people with diabetes increasingly living longer.
Diabetic retinopathy continues to be an important cause of vision impairment, particularly in younger, economically active age groups and is an emerging cause of blindness in many regions of Asia and sub-Saharan Africa. Of concern is that in comparison to cataract and refractive disorders, the management of severe diabetic retinopathy requires a disproportionate amount of resources, including the availability of ophthalmologists.
Furthermore, for every person that experiences vision impairment and blindness from diabetic retinopathy, there are many more living with early stage diabetic retinopathy who need comprehensive and integrated people centred eye care services to prevent vision loss.
