CREWT Medical Systems, Inc. proudly introducing the sophisticated newly developed Automated Perimeter,
IMOvifaTM. Our patented technology, Binocular Random test enables patients comfort, ease of use andspeedy accurate visual ﬁeld testing that with reliable result.
<Both eyes open, No require an eye patch for Occlusion><No require Dark-room>

IMOvifaTM allows random single eye test with botheyes open . Since this random test with both eyes open
does not require covering one eye, a subject no longer
feels discomfort when undergoing a test with a patch
covering one eye, and stability for the tested eye isachieved from the binocular ﬁxation.

IMOvifaTM is portable. It
does not require a dark roomthat
conventional
SAP
needs, allowing the test to
be performed in every room.
Certainly, the test could be
performed away from theclinic.

<Original Threshold test library : 24plus>
In addition to 30-2 and 24-2 test patterns commonlyused for conventional SAP, IMOvifaTM is equipped withthe world-ﬁrst 24plus test pattern which increases thedensity of central test points. 24plus is the original
pattern with increased density of test points in themacular region by adding a part of 10-2 test points thatis the central test pattern based on 24-2 test points. It
is also equipped with 24plus (1) pattern with 36 points
extracted from points where glaucoma is commonly
found within the 24plus pattern. 24plus (1) allows tocomplete the test even faster (90 seconds for onenormal eye) and is the optimum test pattern forscreening.
