Scanning laser ophthalmoscope correlations with biomicroscopic findings and foveal function after macular hole closure

Objective: To investigate the relation between foveal findings and visual f unction in eyes with a resolved idiopathic macular hole after Vitreous surg ery. Methods: We divided 28 eyes with postoperative idiopathic macular hole reso lution into 3 groups based on postoperative biomicroscopic foveal findings of complete closure, partial closure, or atrophic closure. To evaluate fove al retinal function, scanning laser ophthalmoscope (SLO) microperimetry was performed preoperatively and 6 months postoperatively. Results: Postoperatively in 18 eyes (64%), the foveal images became normal or almost normal and were classified as having complete closure, 6 eyes (21 %) were classified as having partial closure, and 4 eyes (14%) as having at rophic closure. The corresponding visual acuity levels 6 months postoperati vely were, respectively, 0.10, 0.35, and 0.64 (P < .01) based on LogMAR ana lysis. Preoperative SLO microperimetry detected an absolute scotoma at the bottom of all macular holes; postoperatively, the absolute scotoma disappea red in the 18 eyes with complete hole closure, but a relative scotoma was d etected in 6 eyes. Of 6 eyes with partial closure, 1 had an absolute scotom a and 5 had a relative scotoma. An absolute scotoma was detected in 4 eyes with atrophic closure. Conclusions: After macular hole closure, SLO findings correlate both with b iomicroscopic findings and foveal function. Better anatomical foveal recove ry in eyes after macular hole closure results in better improvement of visi on than in eyes in which the foveal anatomical findings are not as good.
