Purpose:
To report unusual fundus findings in two cases of melanoma-associated retinopathy.
Methods:
Observational case reports. The histories of two patients with melanoma-associated retinopathy were reviewed. Sera from both patients were examined for antibodies against retinal bipolar cells. Immunofluorescence was performed on cryostat sections of unfixed normal human retinas. Sera and IgG from both patients were tested against a known melanoma-associated retinopathy patient as well as a control subject.
Results:
Our patients had metastatic, cutaneous melanoma and a clinical syndrome consistent with melanoma-associated retinopathy. Both patients had serum antibodies that were reactive against retinal bipolar cells. They had unusual fundus changes not previously described in association with melanoma-associated retinopathy. One patient also developed vitiligo.
Conclusion:
Patients with metastatic cutaneous melanoma and melanoma-associated retinopathy may present unusual fundus lesions that may be caused by autoimmunity which is part of the clinical picture of melanoma-associated retinopathy or metastatic melanoma.
