Changing trends in pseudoretinoblastoma diagnoses: A 10 year review from the United Kingdom.

Aim: To study the different types and frequency of pseudoretinoblastoma (pseudoRB) lesions who present to a retinoblastoma centre due to concern that the condition may be retinoblastoma.

Methods: A retrospective chart review of 341 patients presenting sporadically to the Royal London Hospital from January 2009 to December 2018.

Results: 220 patients (65%) were confirmed to have retinoblastoma, while 121 (35%) had pseudoRB.
