Single-cell transcriptomics enable the characterization of local extension in retinoblastoma

Communications Biology
Retinoblastoma (RB) is the most prevalent ocular tumor of childhood, and its extraocular invasion significantly increases the risk of metastasis. Nevertheless, a single-cell characterization of RB local extension has been lacking. Here, we perform single-

Local extraocular extension of retinoblastoma following intraocular surgery. [PDF]

British Journal of Ophthalmology, 1989
Three cases of local extraocular extension of retinoblastoma following intraocular surgery via a transscleral approach have been seen in one centre during a 12-month period. This number represents a significant increase on the previous incidence of this serious complication, which may be related to more widespread use of vitrectomy techniques.
