After preoperative assessment revealed anomalous posterior vitreous detachment, a 75-year-old woman affected with retinal detachment due to macular hole was scheduled to undergo the posterior episcleral buckling procedure. Preoperative microperimetry showed unstable eccentric fixation with a dense scotoma within the central 8 degrees. One month postoperatively, best-corrected visual acuity increased from 1.70 to 0.88 logarithm of the minimum angle of resolution. Ultrasonography and optical coherence tomography revealed the indentation of the posterior scleral profile due to the buckle. The retina appeared fully attached and a macular hole with flattened edges was still detectable. Microperimetry showed stable central fixation with recovery of retinal sensitivity within the central 2 degrees. Diagnostic imaging techniques guided the decision to use the posterior episcleral buckling procedure. Microperimetry was useful to explain vision improvement despite residual macular hole.

Purpose: To investigate the impact of foveal glial tissue on the anatomical and functional results after macular hole (MH) surgery.
Methods: This study included 141 consecutive eyes that underwent successful vitrectomy for full-thickness MH between January 2015 and December 2022. The best-corrected visual acuity (BCVA) and the length of outer retinal defects were evaluated preoperatively and at 6 months postoperatively.

Background: This study investigated the association between photoreceptor structural restoration and visual function outcomes in patients undergoing surgery for closed macular holes (MHs). Using adaptive optics scanning laser ophthalmoscopy (AOSLO) and microperimetry, we aimed to provide a more detailed understanding of photoreceptor recovery and visual improvement in closed MHs.
Methods: We conducted a retrospective observational study of 31 eyes of 28 patients who underwent vitrectomy with internal limiting membrane (ILM) peeling to treat idiopathic MHs.
