Comparison of Physiologic versus Pharmacologic Mydriasis on Anterior Chamber Angle Measurements Using Spectral Domain Optical Coherence Tomography

Table 1

Effect of differing lighting conditions and pharmacologic dilation on pupil size and angle metrics obtained with Cirrus. Results are presented as mean ± standard deviation.

	Light	Dark	Pharmacologic dilation	value
Pupil size (mm)	4.00 ± 0.81	5.27 ± 0.77	6.54 ± 0.76	overall: <0.001^1; ()-(): <0.001^2; ()–(): <0.001^2; ()-(): <0.001^2
SL-AOD (mm)	0.87 ± 0.31	0.75 ± 0.29	0.9 ± 0.38	overall: <0.001^1; ()-(): <0.001^2; ()–(): 0.001^2; ()-(): <0.001^2
SL-TISA (mm^2)	0.33 ± 0.14	0.29 ± 0.13	0.34 ± 0.17	overall: 0.003^1; ()-(): <0.001^2; ()–(): 0.057^2; ()-(): <0.001^2
