Pars plana vitrectomy with gas tamponade for lamellar macular holes.

Purpose To report anatomic and visual improvement after pars plana vitrectomy with gas tamponade for a lamellar macular hole with poor central visual acuity. Design Two interventional case reports. Methods Two patients with a lamellar macular hole underwent vitrectomy, internal limiting membrane peeling, and long-acting gas injection. Main outcome measures included best-corrected visual acuity, biomicroscopic appearance, and optical coherence tomography findings. Results Vitrectomy with gas tamponade resulted in biomicroscopic, functional, and tomographic improvement in both patients for follow-up periods of 12 months. Conclusions Vitrectomy with gas tamponade may be an effective method for a lamellar macular hole with poor visual acuity.
