Nationwide trends and incidence of blindness in patients with diabetic retinopathy identified using an age-period-cohort analysis.

ABSTRACT:

Objectives

To estimate the epidemiologic trends of blindness in patients with diabetic retinopathy (DR) and investigate the age-, period-, and cohort-specific effects on blindness.

Methods

A total of 2.5 million patients with DR aged 20 years or older were included from the Korean National Health Claims database from 2005 to 2019. Non-proliferative DR/ proliferative DR (NPDR/PDR) cohorts were constructed separately. Participants were identified as having a blindness in at least one eye. The incidence of blindness were calculated using a log-linear Poisson age-period-cohort (APC) analysis model, each effect on blindness were estimated for each study group.

Results

The incidence of blindness was 1326.62 per 100,000 in the NPDR group and 3397.57 in the PDR group. The bli
