Vitreous Surgery for Giant Temporal Intrachoroidal Cavitation.

A 50-year-old woman had visual disturbance in her left eye. Optical coherence tomography (OCT) revealed an epiretinal membrane (ERM) and a giant peripapillary intrachoroidal cavitation (ICC). Best-corrected visual acuity (BCVA) was 15/50 in the left eye with central visual field (VF) impairment. We performed vitrectomy with internal limiting membrane "stuffing" into the sinkhole, as well as peeling of the ERM. One year after surgery, even though ocular blood flow had decreased and the VF impairment had worsened, OCT demonstrated that the ICC had completely disappeared, and BCVA had improved to 25/50. Although this technique can increase BCVA, the potential surgical risk of exacerbating VF impairment calls for careful consideration on a case-by-case basis. .
