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).

The prognosis in Rb directly relates to the spread of disease beyond the eye, particularly to the central nervous system. Therefore, until the recent past, surgically entering an eye with active or recently active Rb was absolutely contraindicated in most centres around the world due to the risk of iatrogenic extraocular spread.</p><p><strong>Summary: </strong>In this review article, we explore the role of intraocular surgery in Rb. We describe the techniques which have been developed in order to safely deliver chemotherapeutic agents into the eye, both intravitreal and intracameral. We discuss the role of vitrectomy and endoresection for treatment of vitreous seeds and active retinal tumours. In the context of previously treated Rb, we outline various surgical interventions performed to improve visual outcomes or to manage the ocular sequelae of the disease. In particular, we review the various techniques used to maximise the safety of cataract, retinal and glaucoma surgery in children with a history of Rb.</p><p><strong>Key messages: </strong>The role of intraocular surgery in Rb is now well established, particularly in the delivery of chemotherapeutic agents or in the presence of previously treated diseases. The role of intraocular surgery in eyes with active Rb is less well established and remains the subject of much debate.
