Purpose: : Visual recovery after surgery for macula-off retinal detachment (RD) is often discouraging because, despite a complete retinal adhesion, performances are very limited. We evaluated if microperimetric biofeedback can increase visual acuity in operated eyes.

Methods: : 42 eyes that underwent surgery for RD between 2008 and early 2011 were selected. Patients were divided in two groups:group A, 20 eyes (10 had undergone scleral buckle procedure,10 pars plana vitrectomy and silicone oil tamponade (PPV)) were treated with biofeedback visual training with pattern stimulation performed with MP-1 (Nidek Technologies, Italy); group B, 22 eyes (10 with scleral buckle procedure, 12 PPV) served as control. Biofeedback strategy (1 session a week for 10 weeks) started 15 days after the suspension of cicloplegic treatment in buckling procedure or after silicone oil removal in PPV. Patients best corrected visual acuity (BCVA) was examined with Snellen chart at baseline and 6, 12,18 weeks. Student t test was used for statistical analysis, p<0.05 was considered significant.

Results: : At baseline BCVA for both groups was similar, 0.43±0.13 and 0.45±0.12 for group A and group B respectively (p=0.4230), at 6-week follow-up BCVA for group A was significantly better (p=0.0012), 0.73±0.23 and 0.48±0.17 for group A and group B respectively. At 12-weeks follow-up BCVA was 0.81±0.075 for group A and 0.56±0.32 for group B (p=0,028), and at 18-weeks follow-up BCVA was 0.85±0.05 and 0.67±2.08 for group A and group B respectively (p=0,041).

Conclusions: : Biofeedback training increases BCVA after RD surgery and the improvement compared to controls remains stable after 8 weeks from treatment. The use of pattern stimulation, with highly informative black-and-white flickering checkerboard that alternate at 4Hz, probably improves receptive fields activity after RD surgery thus increasing BCVA.
