Abstract

Purpose:

To review enhanced depth imaging optical coherence tomography of intraocular tumors.

Methods:

Review of tumor surface topography and internal characteristics based on published reports and personal experience.

Results:

Using enhanced depth imaging optical coherence tomography, choroidal nevus showed smooth moderate dome-shape and with overlying retinal pigment epithelial alterations, subretinal cleft, and photoreceptor loss. Choroidal melanoma was smooth, moderately dome-shaped, and with overlying “shaggy” photoreceptors. Choroidal metastasis showed “lumpy, bumpy” irregular surface topography, subretinal fluid, and shaggy photoreceptors. Choroidal hemangioma was smooth, acutely dome-shaped and with subretinal fluid and/or cystoid retinal edema. Choroidal lymphoma showed “placid, rippled, or seasick” surface, correlating with increasing tumor thickness. Choroidal osteoma displayed smooth undulating surface with intralesional lamellar lines and tubules, representing bone lamellae or vessels. Choroidal melanocytosis produced flat but uniformly thickened choroid with increased stromal density. Choroidal hemorrhage displayed slightly “scalloped” surface in the outer choroid. All choroidal tumors showed inward compression of the choroidal vasculature, except for hemangioma in which the vessels were expanded. Sclerochoroidal calcification arose within the sclera as a “rocky” or “rolling” topography and solitary idiopathic choroiditis appeared as a domed or “volcanic” focal scleral thickening, each causing intense choroidal compression. Retinal tumors such as small retinoblastoma, astrocytic hamartoma, and hemangioblastoma arose abruptly adjacent to normal retina. Exophytic retinoblastoma and retinal hemangioblastoma depicted a full-thickness disorganized retinal mass with normal retina draped over the margins. Flat astrocytic hamartoma arose within the nerve fiber layer, and thicker tumors involved full-thickness retina with “moth-eaten” or cavitary appearance. Retinal pigment epithelial lesions such as congenital hypertrophy of retinal pigment epithelial showed flat topography with transmission of light through lacunae, occasional subretinal cleft and uniform photoreceptor loss, whereas combined hamartoma of retina/retinal pigment epithelial showed “sawtooth” pattern of vitreoretinal traction leading to mini-peak or maxi-peak retinal folds.

Conclusions:

Enhanced depth imaging optical coherence tomography shows characteristic topographical and intralesional patterns that appear to be suggestive for selected intraocular tumors.
