Optical coherence tomography of melanocytoma

PURPOSE: To evaluate the use of optical coherence tomography in differentiating between melanocytoma and choroidal melanoma. METHODS: Case reports. Three consecutive patients with melanocytoma were scanned using optical coherence tomography. RESULTS: Optical coherence tomography showed lesions with a high reflectance signal anteriorly and optical shadowing behind, corresponding to the melanocytomas. The high signal was continuous with the retinal nerve fiber layer, consistent with known growth patterns of melanocytoma. CONCLUSION: Optical coherence tomography may be useful in differentiating melanocytoma from choroidal melanocytic lesions.
