Interim analysis of 12-month patient-reported vision-related functioning and treatment satisfaction outcomes from patients in the RELIGHT study of ranibizumab for the treatment of visual impairment due to diabetic macular oedema (DMO).

Patients enrolled in the prospective, open-label, multicentre, single-arm, 18-month RELIGHT Study (NCT01257815) were assessed at 20 UK clinical sites.

Patients with visual impairment due to DMO received three monthly initiation doses of ranibizumab 0.5 mg followed by individualized treatment as needed, with monthly follow-up for the first three months and subsequent follow-up every two months. Self-reported visual functioning and satisfaction with treatment were assessed using the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25; scored 0-100) and the 13-item Macular Disease Treatment Satisfaction Questionnaire (MacTSQ; scored 0-72), respectively. The NEI VFQ-25 was administered at months 0, 6, 12 and 18, and the MacTSQ at months 1, 6, 12 and 18. For both instruments, composite and subscale scores were calculated according to the developer's guidelines.

Results and Conclusion
Of 139 patients screened, 110 were treated. At enrolment the mean age was 64 years and 71% were male. The median number of treatments over 12 months was 7 (range, 3-9). At month 12, BCVA improved from a baseline mean of 62.6 letters to 67.8 (mean change, +5.2 letters). The mean NEI VFQ-25 composite score was 66.9 at baseline and increased by 6.0 points to 72.9 at month 12 (n = 99; p = 0.0004). Significant gains were reported in eight of eleven vision-related subscale scores, including general vision (+5.3; p = 0.011), near activities (+5.3; p = 0.017), distance activities (+6.4; p = 0.004) and mental health (+10.2; p < 0.001). The overall MacTSQ score increased from 62.1 at month 1 to 64.7 at month 6 (+2.6; n = 100; p < 0.001) and 66.7 at month 12 (+4.2; n = 98; p < 0.001). The increase in MacTSQ impact of treatment subscale score from baseline to month 12 was +3.4 (n = 98; p < 0.001).

The positive changes in the composite and individual subscale scores of the NEI VFQ-25 were generally in excess of the 5-point increases shown to reflect clinically significant differences in DMO and other ocular diseases. Our findings confirm improved patient functioning as a consequence of ranibizumab treatment in patients with DMO. The improvements in MacTSQ scores demonstrate the acceptability of the individualized treatment regimens of the RELIGHT study.
