To study the effects of the use of a CCTV with and without additional training on self reported quality of life.
In a multicenter randomised controlled trial (RCT) among 122 subjects, a treatment group, receiving both the delivery instructions from the supplier and training in the use of a CCTV, was compared to a control group, receiving only the delivery instructions. The Low Vision Quality of Life questionnaire (LVQOL), EuroQol 5 dimension, Center for Epidemiologic Studies Depression scale (CES-D) and Adaptation to age related Vision Loss scale (AVL) were used as outcome measures.
Neither on the Euroqol, the CES-D or the AVL, a significant difference was found between the baseline measurements and measurements three months after receiving the CCTV. On the LVQOL, a significant improvement (p<0,001) was found on the dimension "reading and fine work" whereas no difference was found on the other dimensions. Only on the Euroqol a significant treatment effect was found (mean difference 0.07: p = 0.04.
As expected, providing a CCTV increases vision related quality of life on the dimension reading and fine work. Other dimensions did not change. Training in the use of a CCTV was protective for further quality of life decline. Based on the results of these study, CCTV-training seems redundant.
