Measuring the Ocular Morphological Parameters of Guinea Pig Eye with Edge Detection and Curve Fitting

Table 1

Comparison of ocular morphological parameters between anterior and posterior surface.

Parameters	Anterior surface	Posterior surface
Maximum axis (mm)			0.30	0.77
Minimum axis (mm)			4.15	<0.01
Eccentricity			3.41	<0.01
Horizontal axis (mm)			-0.70	0.48
Vertical axis (mm)			-2.31	0.03
Transverse area (mm^2)			-1.93	0.06
Perimeter (mm)			-1.93	0.06
Tilt angle (°)			-1.15	0.26

Note: the tilt angle in the table in anterior surface was angle_{long axis}; in contrast, the tilt angle in posterior surface was 180°- angle_{long axis}.
