Peripheral Anterior Chamber Depth Analyzer SPAC
Non-contact quantitative measurement of anterior chamber depthsNon-contact quantitative measurement of anterior chamber depths
SPAC continually measures the anterior chamber depths from corneal center to temporal periphery, and automatically evaluates the risks of the patient developing angle-closure glaucoma; a useful tool in screening for patients with angle-closure glaucoma or with the potential to develop one.
* Iridal radius of curvature: Radius of the approximate circle formed by plotting measured points of iris curvature. Where the approximate circle is formed below the iris curvature (i.e. the vertex of the iris curvature is raised upward), “+” is displayed before the radius value, and “-“ is displayed before the value where the circle is formed above the iris curvature (i.e. the vertex of the iris curvature dips downward). While the values of iridal radius of curvature alone cannot be used for diagnosis of angle-closure glaucoma, they can be combined with other data to produce a more accurate diagnosis.
High-precision three dimensional image analysis
This original analysis program developed by Takagi makes instant and highly accurate three-dimensional image analysis possible. Unlike anterior segment OCT’s, there is no need for cumbersome setup. Placing a patient’s chin on the chinrest and pressing the Start button is all that’s required; measurement starts immediately and results are presented. SPAC’s ability to “quantify” data, that has been difficult to achieve with conventional examination methods, facilitates continued monitoring and follow-up of glaucoma patients.
improved reproducibility
Scanner’s light source has been changed from visible light to infrared, and the number of measuring points has been doubled (compared to our conventional model); the new SPAC delivers data analysis of high reproducibility and accuracy more than ever before.
Monitoring patients over time
Monitoring patients’ angles over time is one of the crucial aspects in glaucoma management.
The new SPAC has a database built in the main unit, allowing stored grading and angle information to be readily displayed in chronological graphs (selectable periods: 6 months, 1 year, and 5 years). This enhances the informed consent process, providing patients with comfort and reassurance as well as gaining their trust.
Easy operation with the touch of a screen
All operations from starting tests to ending tests can be performed at the touch of a 10.4” screen. Patient’s eye can also be aligned using the touch screen.
Screen layout is intuitive, allowing examiners to perform hassle-free operation.
Easier paper loading
The new SPAC has eliminated the cumbersome process of feeding or threading the new paper roll through a slot; all examiner has to do is just drop the roll in and close the lid – another hassle-free feature.
An external printer* can be connected to print out the results on A4-size paper.
Anterior chamber depths in 3D images
Anterior chamber depths that have been continually measured from corneal center to temporal periphery can either be printed as per the previous SPAC model or presented in three-dimensional images. The latter method is useful in explaining the results to the patient.
Test results can be printed on A4 size paper where the SPAC is connected to an external printer.
Sample cases
Plateau iris
Pre- and post-laser iridotomy
Examination result grading
SPAC categorizes the anterior chamber depth into 12 grades from Grade 1 (narrow) to Grade 12 (deep), and enables finer grading of the anterior chamber depth. Furthermore, the Suffix attachments S (suspect) and P (potential) to the Grade number represent the potential risk of angle-closure glaucoma.
Note: The result of evalution does not completely determine the potential to develop ACG.
Grade=9
No evalution mark (× or △) is indicated at any measurement point. In such cases, S (suspect) or P (potential) is not indicated for the numerical value that represents the evaluation grade.
Grade=7
No evalution mark (× or △) is indicated at any measurement point. In such cases, S (suspect) or P (potential) is not indicated for the numerical value that represents the evaluation grade.
Grade=5P
The △ mark of the evaluation mark (×or △) is indicated at 8 or more measurement points. In such cases, P (potential) is indicated for the numerical value that represents the evaluation grade.
Grade=3S
The × mark is indicated at 8 or more measurement points. In such cases, S (suspect) is indicated for the numerical value that represents the evaluation grade.
