Imaging of endogenous Candida endophthalmitis (ECE) demonstrated by Zhuang et al. [1], now with labeling overlay (white markings). These examples of ECE (classified as “retinal” lesion types 1–4, respectively) demonstrate primary choroidal involvement (a), and shadowing that cannot establish a retinal origin or exclude choroidal origin (b-d). a Disrupted architecture of inner choroid (double arrow) extending into the overlying retinal pigment epithelium and neurosensory retina is consistent with a primarily choroidal infiltrative and inflammatory process. b Posterior shadowing (double arrow) is found approximate in size to the overlying, anterior aspect of a large hyperreflective structure (*). Lesion origin cannot be determined because the view of the choroid and outer retina is overshadowed (double arrows), but cystic changes are apparent in outer retina adjacent to the edges of shadowing (arrowheads) which suggest a possibly deep lesion origin. c Posterior extent of hyperreflectivity is seen extending at least into deep retina (arrowhead), surrounded by neurosensory retinal detachment and extensive shadowing that completely obscures underlying choroid (double arrows). d Large hyperreflective mass (*) with florid inner retinoschisis and secondary shadowing (double arrows) blocks choroidal visualization
