JAMA Ophthalmology Journal Club Slides:Visual Function After Ranibizumab Mitchell P, Bressler N, Tolley K, et al; RESTORE Study Group. Patient-reported visual function outcomes improve after ranibizumab treatment in patients with vision impairment due to diabetic macular edema: randomized clinical trial. JAMA Ophthalmol. Published online August 22, 2013. doi:10.1001/jamaophthalmol.2013.4592.
Introduction • Importance: • Few data are available on relative changes in vision-related function after treatment for diabetic macular edema (DME). • DME is a major cause of visual impairment and can negatively affect patient-reported visual function. • The Ranibizumab Monotherapy or Combined With Laser vs Laser Monotherapy for Diabetic Macular Edema (RESTORE) trial, a phase 3, randomized, double-masked, 12-month study at outpatient retina practices in Australia, Canada, and Europe, showed that ranibizumab therapy (with or without combined laser) was superior to laser alone for improving best-corrected visual acuity in patients with visual impairment due to DME. • Objective: • To determine the impact of intravitreal ranibizumab, 0.5 mg, compared with laser alone on patient-reported visual function using the 25-item National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25) in the RESTORE trial.
Methods • Study participants were assigned randomly to ranibizumab plus sham laser (n = 116), ranibizumab plus laser (n = 118), or sham injections plus laser (n = 111). • Ranibizumab and sham injections were given for 3 consecutive months then as needed based on visual acuity; laser and sham laser treatments were given at baseline then as needed. • The NEI VFQ-25 was administered at baseline and months 3 and 12. • The analysis population included all patients receiving 1 or more study treatments with at least 1 postbaseline NEI VFQ-25 assessment. • Last observation carried forward (LOCF) was used for missing postbaseline data.

Comment • Vision-related, patient-reported outcomes mirror visual acuity outcomes and support superiority of ranibizumab or ranibizumab plus laser treatment over laser monotherapy for patients with DME and characteristics similar to those enrolled in the RESTORE randomized clinical trial. • Subscale analyses suggest that improvements in the NEI VFQ-25 score are most pronounced for the near activities and general vision subscales.
