Purpose:
To report the rare occurrence of new inner nuclear layer cystic spaces occurring in eyes treated with pars plana vitrectomy (PPV) and internal limiting membrane (ILM) removal for idiopathic epimacular membrane (EMM).
Materials And Methods:
Consecutive patients with EMM without preoperative retinal cystic changes undergoing PPV with ILM peeling were retrospectively evaluated. Patients developing a characteristic inner nuclear layer cystic change were analyzed.
Results:
Inner nuclear layer cystic changes appeared in eight of 768 (1.04 %) eyes at a mean postoperative time period of 3.2 ± 0.89 months. No leakage or pooling was demonstrated on postoperative fluorescein angiography. Morphologic characteristics included vertically elongated hyporeflectant spaces within the inner nuclear layer on spectral domain optical coherence tomography (SD-OCT).
Conclusions:
A minority of patients undergoing PPV with ILM peeling develop new, delayed onset, postoperative inner nuclear layer cystic spaces with a characteristic SD-OCT appearance and no evidence of angiographic leakage.
