optic zone diameter 

Diameter of the optic zone (front or back) of a contact lens measured to the surrounding junction. It is commonly specified in millimetres. Specifically, there are the back optic zone diameter (BOZD), formerly called back central optic diameter (BCOD), and the front optic zone diameter (FOZD). It is often difficult to measure these dimensions due to the blending of the line separating the zones, especially for the back optic zone diameter. The region surrounding the central optic zone is the peripheral zone. If there is more than one, the zones will be numbered first, second, etc., beginning with the zone immediately surrounding the central optic zone. The diameter of each peripheral zone is referred to as the back (or front) peripheral zone diameter (BPZD). See blending; total diameter; edge lift.

Here, in the preventive experiment, a significant increase in [T.sub.2] of the OVX bones was found as early as 6 weeks after operation, when measured at the peripheral zone of the metaphysis (a region reach of trabecular bone that interfaces with marrow cells).
There were 169 (21.2%) regions diagnosed with tumors within a total of 798 regions evaluated in the peripheral zone. Among the regions evaluated, the number of regions that scored one to five using T2WI was 72 (9.0%), 507 (63.5%), 153 (19.2%), 57 (7.1%), and nine (1.1%), respectively.
The results, specifically at tADC 1.0x10-3mm2/s, proved "considerably more accurate than PSA alone and offers promise as a tool for not only screening of peripheral zone prostate cancer but potentially also for characterizing its aggressiveness," their findings noted.
To accumulate such high levels of zinc, prostate peripheral zone cells are endowed with a specialized zinc transporter protein called ZIP1.

[17] showed in the peripheral zone ADC maps at b-value 2000 s/[mm.sup.2] little diagnostic advantage in comparison with a b-value of 1000 s/[mm.sup.2], although more recently he reported a significant advantage [18].
