Purpose:
To objectively evaluate the changes in vision-specific quality of life with low vision care at the Royal Society for the Blind (RSB) Low Vision Clinic (LVC).

Methods:
The care model at the RSB LVC is optical management at the initial assessment with subsequent referral for multi-disciplinary services as required. Par-ticipants completed the Impact of Vision Impairment Questionnaire (IVI) and Veteran Affairs Low-Vision Visual Functioning Questionnaire (VALVVFQ-48) prior to initial assessment, at 30 days (to assess the outcome of optical management) and at three months follow-up (to assess the outcome of multi-disciplinary services).

Results:
Using the VALVVFQ-48, an improvement (p < 0.05) was seen at 30 days follow-up in overall visual ability (7.42 ± 4.19 to 6.15 ± 3.75), and the reading (7.44 ± 4.32 to 5.58 ± 4.35), visual information (4.39 ± 3.42 to 3.75 ± 3.01) and visual motor (7.09 ± 4.55 to 5.70 ± 4.11) subscores. However, at three months follow-up all subscores were not significantly different from pre-rehabilitation levels. In contrast, for the IVI, there was no improvement in the overall sub-scale at 30 days follow-up (1.46 ± 1.06 to 1.42 ± 0.92, p = 0.182) but a significant improvement at three months follow-up (1.46 ± 1.06 to 1.74 ± 1.08, p < 0.01). Similarly the mobility subscore showed an improvement after three months only (1.55 ± 1.05 to 1.82 ± 1.15, p < 0.01). Conclusion: The VALVVFQ-48 and IVI demonstrate improvements in quality of life following low-vision rehabilitation. The timing of the observed changes varied between the questionnaires, reflecting the content of the instruments and the timing of delivery of multi-disciplinary services, but also suggests that continued rehabilitation in terms of optical manage-ment may be warranted to maintain a client’s quality of life.
