Background: The purpose of this study was to investigate lamellar macular hole formation in six patients after rhegmatogenous retinal detachment repair.
Methods: A retrospective review of medical records of patients who underwent primary pars plana vitrectomy for rhegmatogenous retinal detachment repair was performed. Optical coherence tomography characteristics and best-corrected visual acuity were evaluated. Patients who developed lamellar macular hole after pars plana vitrectomy for rhegmatogenous retinal detachment repair were identified.
Results: A total of 1185 eyes underwent pars plana vitrectomy for retinal detachment between 2004 and 2009. Optical coherence tomography evaluation was available in 450 cases. Six of these cases demonstrated lamellar macular hole formation, which was diagnosed by OCT-3. The mean time from retinal detachment surgery to lamellar hole diagnosis was 4.1 months. The presence of an epiretinal membrane on the surface of the juxtafoveal retina was a common finding in all six patients. Visual acuity was improved after successful retinal reattachment and remained unchanged after lamellar hole formation.
Conclusion: Lamellar macular holes developing after pars plana vitrectomy is a rare complication. Stability of optical coherence tomography findings and best-corrected visual acuity after lamellar macular hole formation may be observed for at least two years.
