Full-Thickness Macular Hole Progressing from Lamellar Macular Hole with Epiretinal Proliferation

Foveoschisis in association with contractile epiretinal membrane is frequently misdiagnosed as lamellar macular hole (LMH). The progression of true LMH with associated epiretinal proliferation to full-thickness macular hole (FTMH) is probably underestimated. We report a case of bilateral FTMH progressing from LMH with epiretinal proliferation. A 72-year-old male presented with increased blurring of vision in left eye. Visual acuity was 20/40 in right and 20/50 in left eye. Examination showed FTMH with epiretinal proliferation in left eye and LMH with epiretinal proliferation in right eye. Surgery of the left eye achieved successful closure of macular hole with improvement in vision. He presented again a month later with further deterioration of vision in right eye. Examination revealed FTMH in right eye with epiretinal proliferation. Surgery of the right eye also achieved optimum functional and morphological results. This case demonstrates that LMH with epiretinal proliferation may have a propensity to progress to FTMH.
