High-resolution Fourier-domain optical coherence tomography findings in subretinal cysticercosis.

We present the optical coherence tomography features of subretinal cysticercosis in a 12-year-old boy with presenting visual acuity of 4/60. The cyst was imaged using high-resolution Fourier-domain optical coherence tomography system (Cirrus; Zeiss Meditec, Inc, Dublin, CA). Clinical examination revealed a subretinal, domeshaped, cystic lesion below the inferotemporal arcade (Figure 1). Within the cyst, a white opacity with contractile motility was seen during examination (the scolex). Fourier-domain optical coherence tomography revealed a hyporeflective cystic subretinal lesion (Figure 2). The cyst wall facing the vitreal side was continuous and well defined (long arrow, Figure 2) while that abutting the pigment epithelial layer was discontinuous and poorly defined as a result of shadowing (arrow head, Figure 2). The scolex produced a comet-shaped echo with anterior broad hyperreflectivity and a gradually tapering hyporeflective tail (marked “S”; Figure 2). The cyst was removed using standard 3-port 23-G pars plana vitrectomy. Vitrectomy was completed after posterior vitreous detachment induction, and retinotomy was made over the area of the Fig. 1. Fundus photographs of the right eye showing sub retinal cysticercosis below the inferotemporal arcade with overlying retinal vasculature. Scolex is seen within the cyst cavity as a white opacity (arrow).
