  • Calculated from 1 November 2012 (participants needed to be under the age of 55 years as of that date to be eligible for the current study).

  • *Two missing data.

  • †Several participants in the combat-related visual impairment group were still enlisted with the armed forces, but were likely to be medically discharged in due course (n=4).
