Brief Description of the Software
The software is designed to measure the magnitude of expression of the 3 key diagnostic facial features of FAS (short palpebral fissure lengths (PFL), smooth philtrum, and thin upper lip). The software scores the outcomes of these facial measures using the 4-Digit Diagnostic Code.
To use the software, the User:
- Opens 3 digital facial photographs (frontal view, 3/4 view, and lateral view) into the software program.
- Enters name, birth date, photo date, gender, race.
- Measures the 3 facial features using special image analysis tools.
- Documents the presence of other facial anomalies.
- Documents the quality of the photos.
From this information, the software automatically computes the 4-Digit Facial ABC-Score, and the 4-Digit Facial Rank.
- Rank 1, No FAS facial features present
- Rank 2, Mild FAS facial features (only 1 of the 3 features present)
- Rank 3, Moderate FAS facial features (2 of the 3 features present)
- Rank 4, Severe FAS facial features (all 3 of the features present)
The software stores all photo analysis information in an ACCESS database. The User can print a one-page FAS Facial Photographic Analysis Report. The report includes a summary of the facial analysis and a print of the three photos. A facial photographic analysis can be conducted in approximately 10 minutes.
What's New with Version 2.0 (released November 2012)
Version 1.0 was released in 2003. Version 2.0 was released in November 2012. Version 2.0 is downward compatible with Version 1.0, thus Version 1.0 is no longer distributed. A User can upgrade to Version 2.0 without losing the photo analysis data they have accumulated to date using Version 1.0.
Version 2.0 provides the following new features:
- Two additional palpebral fissure length (PFL) normal growth charts are included: Canadian and Scandinavian. These new charts are considered more accurate growth charts for Caucasian PFLs than the Hall (1989) Caucasian PFL charts. Click here for more details on which PFL growth charts to use. Version 2.0 continues to provide the Hall Caucasian PFL growth charts and the Iosub African American PFL growth charts.
- Version 1.0 required all photo analysis data to be stored in a single database named data.fas. This database could only be stored in the software's data directory. Version 2.0 allows the User to assign any name to the database file and place it anywhere on their hard drive or server.
