Our faculty and graduates develop tools and resources to support clinical practice in vision rehabilitation. The resources below include assessment tools and reference data designed to help vision rehabilitation professionals evaluate performance and provide effective services to their clients.
Some resources may be downloaded and shared freely. Please follow the copyright requirements listed with each downloadable tool.
Revised Self-Report Assessment of Functional Visual Performance (R-SRAFVP)
Certificate graduates Cheryl Zemina and Marlene Snow updated and established the psychometrics for a revised version of the SRAFVP as part of their post-professional graduate work at UAB. The resulting R-SRAFVP form more accurately reflects the activities completed by older adults in the digital age.
The R-SRAFVP is freely available to any professional who wishes to use the form and adhere to the copyright requirements.
The toolkit contains the following items:
- A guide to using the form including copyright requirements, how the form was developed, its psychometric properties, instructions for administering the form and calculating a Medicare g-code, and a case example.
- The R-SRAFVP forms and task descriptions.
- A spreadsheet version of the form that automatically calculates the number of relevant measures, the composite score, the percentage of disability and the g-code levels. Instructions and a client example are included.
- Educational materials on g-code reporting.
Self-Report Assessment of Functional Visual Performance
The SRAFVP is an ADL assessment that focuses on 38 vision-dependent ADL tasks.
The assessment was developed through a collaboration between the occupational therapy departments at the Eye Foundation, University of Missouri-Kansas City, Washington University and the University of Florida. UAB serves as the repository site for the form and the toolkit.
The assessment was developed with a grant from the American Occupational Therapy Foundation and is freely available to any professional who wishes to use the form and adhere to the copyright requirements.
The SRAFVP toolkit contains the following items:
- A guide to using the form including how it was developed and its psychometric properties, copyright requirements, instructions for administering the form and calculating a Medicare g-code.
- The SRAFVP form in four different formats
- Spreadsheet version of the form that automatically calculates the number of relevant measures, the composite score, the percentage of disability and the initial g-code levels.
Age Group Comparisons on the Dynavision
Our graduate students have collected data to establish norms on typical adult performance on the Dynavision for five age groups of typical males and females between the ages of 20 and 70 years. There are 25 males and 25 females in each age group.

Preliminary BITS Visual Scanning Reference Data
UAB alumna Lulwah Almulhim, PhD, MSOT, PT, and colleagues collected data from 80 healthy adults to establish reference benchmarks for visual scanning performance using the Bioness Integrated Therapy System (BITS). Adults aged 19 to 29 years and 50 to 59 years completed user-paced and time-paced visual scanning programs, both with and without central fixation.
Tables 3 and 4 in the published British Journal of Occupational Therapy article provide reference data for each age group for accuracy, reaction time, and number of hits at the 25th, 50th, and 75th percentiles. Table 5 compares performance between the two groups.
Reaction time and number of hits were the most sensitive measures for differentiating performance. The authors note that these preliminary benchmarks should be validated in broader populations.
