  • Number of people with occludable angles calculated for urban and rural areas by age and sex standardised rates from Singapore and Mongolia respectively, and includes people with PAC and PACG.

  • Number of people with PAC includes those with PACG.

  • All figures in thousands except incidence of symptomatic episodes.

  • Incidence of symptomatic, “acute” angle closure is expressed as cases per year.

  • Some columns may not add up exactly because of rounding of figures.
