Uveal melanoma is the most frequent primary tumor of the eye in adults but other rare benign intraocular tumors such as leiomyoma, adenoma or ependymomas may also occur. To diagnose them properly is critical to adapt the patient's management, prognosis and follow-up. Ependymomas are exquisitely rare glial tumors arising from the retina, with only three cases reported yet. Primary clinical diagnosis and distinction between benign or malignant tumor is usually not possible without enucleation and histopathologic analysis. Ependymomas are glial tumors, usually occurring during childhood and arising within the central nervous system (CNS, brain or spinal cord). However, they may also occur outside the CNS, either as a primary or a secondary location.</p><p><strong>Case presentations: </strong>Case series from two adults aged 41 and 42 years with blindness and painful eye due to neovascular glaucoma who were enucleated for intraocular tumors.

Sentinel vessels in uveal melanoma could be visualized noninvasively using LSCI, appearing broader and tortuous compared to surrounding vessels.
