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.
