^aMitry et al. reported the 10-year incidence in Scotland without average annual incidence. The 2006 incidence is shown in the table.

^bSasaki et al. only reported age-group incidences for phakic retinal detachments (RD). An annual RD incidence of 9.8 phakic RDs per 100,000 persons and 10.4 phakic, aphakic, or blunt trauma RD per 100,000 persons. The phakic RD incidence is shown in the table.

^cPopulation was presented in millions.
