Retinal detachment in Olmsted County, Minnesota, 1976 through 1995

Ophthalmology. 1999 Jan;106(1):154-9. doi: 10.1016/S0161-6420(99)90018-0.


Objective: To estimate the incidence of rhegmatogenous retinal detachment (RD) in a geographically defined population and to compare the probability of RD in residents after cataract extraction with the probability of RD in residents who did not have cataract extraction.

Design: Rochester Epidemiology Project databases were used to perform a retrospective population-based incidence study of RD diagnosed between 1976 and 1995 with cohort analyses of the influence of risk factors on the occurrence of RD.

Participants: The population of Olmsted County, Minnesota, participated.

Main outcome measure: Incidence rates of RD adjusted to the age and gender distribution of the 1990 U.S. white population were measured.

Results: Three hundred eleven incident cases of rhegmatogenous RD were identified. The mean annual age- and gender-adjusted incidence rate of rhegmatogenous RD was 17.9 per 100,000 persons (95% confidence interval [CI], 15.9-19.9). For idiopathic rhegmatogenous RD alone, the mean annual age- and gender-adjusted incidence rate was 12.6 (95% CI, 10.9-14.3) per 100,000 persons. Ten years after phacoemulsification and extracapsular cataract extraction, the estimated cumulative probability of RD was 5.5 (95% CI, 3.4-7.6) times as high as would have been expected in a similar group of county residents not undergoing cataract surgery.

Conclusions: Cataract surgery is associated with a significantly elevated long-term cumulative probability of retinal detachment.
