Anatomical and Functional Outcomes of Relaxing Parafoveal Nasal Retinotomy for Refractory Macular Hole Repair.

Abstract

This work aimed to assess postoperative outcomes associated with relaxing parafoveal nasal retinotomy for refractory macular hole repair. This was a retrospective interventional study of patients with persistent or recurrent macular holes following 1 or more standard repair procedures with pars plana vitrectomy and internal limiting membrane peeling. Patients received an additional pars plana vitrectomy and relaxing parafoveal nasal retinotomy, followed by fluid-air and air-gas exchange. Key postoperative outcomes included the achievement of macular hole closure and changes in visual acuity from baseline. Thirteen patients with refractory macular holes were included, with a median age of 65 years (range, 49-90 years). The aperture diameter of the 13 macular holes ranged from 180 to 799 µm (median, 538 µm). Vitrectomy and relaxing parafoveal nasal retinotomy were performed in all 13 eyes, and after a median follow-up of 12 months (range, 3-34 months), anatomical closure was achieved in 12 of 13 eyes (92.3%). Overall, visual acuity (mean ± SE) improved significantly from 1.20 ± 0.15 logMAR (approximate Snellen equivalent, 20/320) at baseline to 0.84 ± 0.11 logMAR (Snellen, ∼ 20/125) during postoperative follow-up (P < .05). Central and paracentral scotomas were observed in 8 of 11 eyes with postoperative Humphrey visual field 10-2 and/or 24-2 data available. Relaxing parafoveal nasal retinotomy may be an effective method to promote anatomical closure and improve vision outcomes in patients with recalcitrant macular holes.
