Purpose: To report a case of age-related hypertrophy of the nonpigmented ciliary epithelium (ARH-NPCE) clinically resembling a ciliary body melanoma and report the optical coherence tomography angiography (OCTA) findings associated with this lesion., Observations: A 51-year-old male was referred for evaluation of a deeply pigmented ciliary body mass with extension through the iris root. Iridocyclectomy was performed due to concern for ciliary body melanoma. Histopathologic analysis was instead consistent with ARH-NPCE, also known as Fuchs' adenoma. Prior to surgery, OCTA images revealed abnormal vasculature in the area of the lesion. Vessels in the peripheral iris approaching the lesion appeared more tortuous and were non-radial as compared with normal iris vessels. The ciliary body mass itself could not be penetrated using an OCTA system operating at 1050 nm., Conclusions and Importance: ARH-NPCE may clinically resemble a pigmented ciliary body melanoma. This is the second case describing this clinical scenario, which may be more common than previously thought. Non-invasive imaging with OCTA revealed an abnormal peripheral iris vasculature pattern in the area of the iridociliary mass characterized by disorganized, tortuous, and non-radial vessels. Despite advances in longer wavelength OCTA systems, poor penetration of the ciliary body lesion precluded imaging of the intratumoral vessels in this location.

We report the case of a 54-year-old female who was referred to us with an amelanotic mass on the posterior pole of the left eye involving the macula. Fundus fluorescein angiography revealed a hyperfluorescent choroidal mass. Indocyanine green chorioangiography revealed a hypofluorescent choroidal lesion with hyperfluorescent margins. B-scan ultrasonography showed a choroidal mass with moderate reflectivity. Choroidal biopsy was performed, which revealed the diagnosis of Fuchs' adenoma.
