Table 1 Known methods for measuring the iridocorneal angle and their definitions
From: Methods of measuring the iridocorneal angle in tomographic images of the anterior segment of the eye
Method symbol | Method name | Definition |
|---|---|---|
AOD | Angle Opening Distance | (Figure 2a) involves measuring a distance between a point of the cornea which is 500 μm away from the scleral spur and the opposite point of the iris |
TIA | Trabecular-Iris Angle | (Figure 2b) involves a direct measurement of the angle |
TISA | Trabecular-Iris Space Area | (Figure 2c) involves measuring an area covering 500 μm located in the area bounded by the cornea and the iris |
