Abstract
PURPOSE: To evaluate the outer retinal microstructure and visual function after idiopathic macular hole (MH) surgery using internal limiting membrane (ILM) peeling with and without Brilliant Blue G (BBG) staining. STUDY DESIGN: Retrospective, consecutive case series. METHODS: A total of 49 eyes of 47 patients were enrolled: 23 eyes of 23 patients with MH who underwent ILM peeling without dyes (control group) and 26 eyes of 26 patients who underwent BBG staining (BBG group). The lengths of defects of the photoreceptor ellipsoid zone (EZ), external limiting membrane (ELM), and interdigitation zone (IZ) were measured. RESULTS: The rate of MH closure after initial surgery was 95.6% (22/23 eyes) for the control group versus 100% (26/26 eyes) for the BBG group. In the 48 eyes with MH closure, the recovery rate of ELM deficiency and change in IZ deficiency showed no difference between the groups. The changes in EZ deficiency at 1 and 12 months were greater in the BBG group than in the control group. (P = 0.047 and 0.031). Visual acuity was better in the BBG group than in the control group during 12 months postoperatively (P < 0.001-0.038). CONCLUSION: Eyes undergoing BBG-assisted MH surgery achieved faster recovery of the outer retinal structures and greater visual improvement than those of eyes without BBG.
