    Summary

    Black hypopyon and keratic precipitates in two patients were caused by intraocular melanoma. This included primary choroidal melanoma and metastatic uveal melanoma, confirmed by histology.

    Area of Science:

    • Ophthalmology
    • Oncology
    • Pathology

    Background:

    • Intraocular melanoma can present with varied clinical signs.
    • Ocular inflammation may be a manifestation of intraocular tumors.

    Purpose of the Study:

    • To describe two cases of intraocular melanoma presenting with black hypopyon and black keratic precipitates.
    • To highlight the diagnostic challenges and histological findings in these presentations.

    Main Methods:

    • Case report of two patients with intraocular melanoma.
    • Clinical examination, including assessment of media opacity.
    • Histopathological examination of ocular tissues.

    Main Results:

    • Black hypopyon and keratic precipitates were observed in both patients.
    • One case involved a primary choroidal melanoma with opaque media.
    • The second case featured uveal metastasis from cutaneous melanoma.

    Conclusions:

    • Black hypopyon and keratic precipitates can be indicative of intraocular melanoma.
    • Histology confirmed the presence of pigment-laden macrophages and melanoma cells in the hypopyon.
    • Early recognition is crucial for appropriate management of intraocular melanoma.
