SEQUENTIAL PARS PLANA VITRECTOMY AND INVERTED INTERNAL LIMITING MEMBRANE FLAP TECHNIQUE FOR RHEGMATOGENOUS RETINAL DETACHMENTS WITH PERIPHERAL BREAKS AND CONCOMITANT NONCAUSATIVE MACULAR HOLE IN NONHIGHLY MYOPIC PATIENTS.

PURPOSE

To present the anatomical and functional results of sequential pars plana vitrectomy for treating rhegmatogenous retinal detachment with peripheral breaks and concomitant noncausative macular holes (MHs) in nonhighly myopic patients.

METHODS

Medical records of patients who underwent rhegmatogenous retinal detachment surgical repair between 2017 and 2023 were reviewed. Of 980 patients with rhegmatogenous retinal detachment, 10 had concurrent MH and underwent sequential pars plana vitrectomy for rhegmatogenous retinal detachment repair and air endotamponade, followed by MH repair using the inverted internal limiting membrane flap technique and C2F6 endotamponade after a minimum of 1 week. The main outcomes measured were best-corrected visual acuity change, retinal reattachment rate, MH closure rate, and closure type.

RESULTS

The retinal reattachment rate was 90% after the primary surgery and 100% after subsequent surgery. Macular hole closure was achieved in all cases. Macular hole diameters ranged from 291 to 702 µm. Anatomical recovery showed mainly 1A closure types (90%). Functional recovery demonstrated significant best-corrected visual acuity improvement, with a mean visual acuity gain of 1.58 ± 0.41 the logarithm of the minimum angle of resolution.

CONCLUSION

For this infrequent pathology, sequential surgery using the inverted internal limiting membrane flap technique and air/gas endotamponade yielded favorable anatomical and functional outcomes. This controlled and standardized approach using sequential surgeries contributes to the achievement of consistent results.
