PURPOSE: The purpose was to evaluate the features of circumscribed @entity3193 using spectral-domain enhanced depth imaging optical coherence tomography (EDI- @entity6653 ). DESIGN: Retrospective observational case series. @entity1 : Ten @entity1 with newly diagnosed circumscribed @entity3193 . METHODS: Spectral-domain EDI- @entity6653 was performed with a Heidelberg Spectralis HRA + @entity6653 (Heidelberg Engineering, Heidelberg, Germany). MAIN OUTCOME MEASURES: Tumor thickness and EDI- @entity6653 features. RESULTS: The mean @entity5 diameter for all eyes was 5.4 mm and mean @entity5 thickness was 1187  m by EDI- @entity6653 compared to 2400  m by ultrasonography. EDI- @entity6653 imaged all @entity5 as smooth with a gently sloping anterior contour, gradual choroidal expansion, expansion of medium and large size choroidal vessels without compression of choriocapillaris, and intact Bruch's membrane (n = 10, 100%). The height of the medium and large @entity5 compared to normal medium and large vessels was comparatively increased by a mean of 265% (medium vessels) and 576% (large vessels). Outer @entity989 included subretinal fluid (n = 7, 70%), lipofuscin deposition (n = 1, 10%), irregularity and thinning of retinal pigment epithelium and @entity2048 or irregularity of the ellipsoid layer (n = 4, 40%), absent external limiting membrane (n = 2, 20%), and disruption of the outer nuclear layer and outer plexiform layer (n = 3, 30%). The inner @entity989 included irregularity of inner nuclear layer and structural loss or @entity4 of @entity389 (n = 3, 30%). The ganglion cell layer and nerve fiber layer were intact (n = 10, 100%). CONCLUSION: EDI- @entity6653 of circumscribed @entity3193 depicts a smooth, gently sloping choroidal mass with expansion of medium and large size choroidal vessels without compression of the choriocapillaris. @entity989 were noted.
