  1. DLDP dependent lateral decubitus position, IOP intraocular pressure; OPP, ocular perfusion pressure
  2. T1, sitting position; T2, 10 min after supine position; T3, 10 min after right lateral decubitus position; T4, 10 min after supine position; T5, 10 min after left lateral decubitus position; T6, 10 min after supine position
  3. Data are described as the mean ± standard deviation (minimum–maximum)
  4. * Wilcoxon signed-rank test
  5. aThe DLDP was defined as the position when the eye of interest (affected or unaffected) was placed on the dependent (lower) side in lateral decubitus position
