    PURPOSE. In addition to performance-based measures, visionrelated quality of life (QOL) and other subjective measures of psychosocial functioning are considered important outcomes of training in the visually impaired. In a multicenter, masked, randomized controlled trial, subjective effects of training in the use of closed-circuit televisions (CCTV) were investigated. METHODS. Patients (n 1/4 122) were randomized either to a treatment group that received usual delivery instructions from the supplier combined with concise outpatient training, or to a control group that received delivery instructions only. Subjective outcomes were the Low Vision Quality-of-Life Questionnaire (LVQOL), EuroQOL 5 Dimensions, Adaptation to Age- Related Vision Loss (AVL), and the Center of Epidemiologic Studies Depression scales. Linear mixed models were used to investigate treatment effects. Differential effects of patient characteristics were studied by implementing higher order interactions into the models. RESULTS. From baseline to follow-up, all patients perceived significantly less problems on the reading and fine work dimension (-28.8 points; P < 0.001) and the adaptation dimension (-4.67 points; P 1/4 0.04) of the LVQOL. However, no treatment effect was found based on the intention-to-treat analysis. CONCLUSIONS. This study demonstrated the effect of receiving and using a CCTV on two vision-related QOL dimensions; however, outpatient training in the use of CCTVs had no additional value. © 2012 The Association for Research in Vision and Ophthalmology, Inc.
