Background

Diabetes prevalence is increasing in Taiwan, raising concern over vision impairment among affected individuals.

Purpose

This study aimed to assess the burden of cause-specific vision impairment among individuals with diabetes, overall and stratified by age, sex, geographic region, and time, with a particular focus on diabetic retinopathy (diabetic retinopathy).

Methods

A cross-sectional, annual analysis was conducted from 2010 to 2020.

n = 1000 individuals
Results
50.8%
diabetic eye damage causes over half of all diabetes-related vision loss
n = 1000 individuals
More results

The age-standardised prevalence per 1000 individuals for diabetic retinopathy-related vision impairment was 0.58 (0.43-0.76), 0.50 (0.36-0.67), 0.12 (0.06-0.20), and 0.09 (0.05-0.17) for mild, moderate, severe, and blindness, respectively.

Higher burdens were observed in females, individuals aged 20-39, and residents of eastern Taiwan.

More results

Between 2010 and 2020, the prevalence of diabetic retinopathy-related vision impairment decreased in the 55-69 age group and increased in the 20-39 age group.

“
Conclusion

This study highlights high-risk subgroups for vision impairment among individuals with diabetes, providing evidence to inform targeted public health and diabetes eye-care strategies.
