Purpose:
To describe a patient with newly developed paracentral acute middle maculopathy after uncomplicated epiretinal membrane removal.
Methods:
Retrospective chart review.
Results:
A 74-year-old white man underwent uncomplicated vitrectomy and epiretinal membrane removal in his left eye. One week later, the patient complained of a small paracentral visual field deficit and decreased visual acuity. Spectral domain optical coherence tomography revealed a characteristic hyperreflective band-like lesion at the level of the inner nuclear layer, consistent with paracentral acute middle maculopathy. The patient was closely followed and endorsed subjective improvement of his paracentral visual deficit at 3 months postoperatively.
Conclusion:
Paracentral acute middle maculopathy, although rare, may be encountered after epiretinal membrane removal.
