Role of 25 MHz Ultrasound Biomicroscopy in the Detection of Subluxated Lenses

Table 1

The measurements of lens position in normal and subluxated subjects obtained with 25 MHz and 50 MHz UBM.

Measurements	25 MHz UBM	50 MHz UBM
The normal eyes
Distance (mm)	1.01 ± 0.20	0.83 ± 0.20	0.001
D-value (mm)	0.01 ± 0.01	0.01 ± 0.01	1.678
The subluxated eyes
Maximum distance (mm)	2.00 ± 0.84	1.64 ± 0.91	0.001
Minimum distance (mm)	0.42 ± 0.41	0.59 ± 0.52	0.029
D-value (mm)	1.54 ± 0.78	1.02 ± 0.74	0.000
Testing time (min)	2.05 ± 0.34	7.48 ± 2.53	0.000
Normal versus subluxated eyes	0.000	0.000

All measuring values are presented as mean ± SD along with 95% confidence intervals (CIs). Distance = the linear distance between the lens equator and the ciliary process; D-value = the difference of the bilateral distance between lens equator and the ciliary process in the same cross section.
