Pilocarpine induces an increase in the anterior chamber angular width in eyes with narrow angles

Table 3

Predictors of changes in angle width identified by multiple regression analysis

Variable r r2 F test Linear regression equation
ACD change 0.769 0.592 21.737 + 0.059 × pretreatment ACD − 28.725
TIA change 0.882 0.778 52.466 −0.031 × pretreatment AOD500 + 13.654
AOD250 change 0.810 0.656 28.586 −0.403 × pretreatment AOD250 +123.837
AOD500 change 0.908 0.824 70.116 −4.978 × pretreatment TIA +159.603

  • ACD=anterior chamber distance; TIA=trabecular-iris angle; AOD250 and AOD500=angle opening distance at 250 μm and 500 μm from the scleral spur.
