| Summary: | Purpose
To propose a novel technique of an internal limiting membrane (ILM) flap using ophthalmic viscoelastic device (OVD) with no requirement for postoperative head posture for the treatment of lamellar macular hole (LMH) repair.
Methods
A retrospective analysis of 16 consecutive eyes of LMH patients who underwent vitrectomy with ILM flap with OVD. Best-corrected visual acuity (BCVA), central macular thickness (CMT), simultaneous cataract extraction, and ellipsoid zone disruption preoperatively and at the final follow-up were compared.
Results
The mean age was 73.19 ± 7.26 years, and ten patients (62%) were females. The mean follow-up was 5.06±1.43 months (range 3–6). For all patients, BCVA was significantly improved at the final visit, from 0.65±0.36 logMAR units to 0.42±0.29 (
p
< 0.001). None of the patients had visual loss. Six patients had epiretinal membrane (ERM) foveoschisis, and the rest had LMH with epiretinal proliferation. Both subgroups presented a significant improvement in their BCVA with a trend for better improvement in the latter (
p
=0.09). Ellipsoid zone disruption was seen in 7 patients including one patient with a macular scar. There was no significant effect of ellipsoid zone disruption on the final BCVA (
p
=0.33). Twelve eyes (75%) underwent simultaneous cataract extraction. Mean BCVA at the final postoperative visit improved regardless of whether the eyes underwent simultaneous cataract surgery (
p
=0.39). CMT was also significantly improved at the final visit, from 200.06±46.8 μm preoperatively to 305.00±85.5 μm (
p
<0.001). No full-thickness macular holes were developed postoperatively. No intraoperative or postoperative complications were observed.
Conclusions
Treatment of LMH with ILM flap with OVD showed promising anatomical and functional results with no postoperative head position requirements. |
