Aim:
To estimate and compare the incidence and characteristics of rhegmatogenous retinal detachments (RRDs) in the Wenzhou area in 2015 to 2019.
Methods:
All newly developed RRD cases among residents of the Wenzhou area, from January 2015 to December 2019, were retrospectively retrieved from hospital records. Annual population data were extracted from the Wenzhou Statistical Yearbook.
Results:
There were 3629 eligible cases. The average incidence of RRD was 7.79 cases per 100 000 population (95% confidence interval, 7.24-8.34), and the incidences were 7.99 and 7.56 for males and females, respectively. The annual incidence increased gradually from 7.26 cases per 100 000 in 2015 to 10.00 cases per 100 000 in 2019, with an overall increase of 37.74%. The highest rate of increase occurred in the age group from 60 to 69 years. Of 2750 eyes with axial length (AL) data, 1675 (60.91%) had an AL greater than 24 mm.
Conclusion:
A trend to increasing RRD incidence is observed in the Wenzhou area over the past 5-year period.
