Overview

Other diagnostic studies for retinoblastoma include fluorescein angiography and electroretinogram.

Other Diagnostic Studies

Fluorescein Angiography

Electroretinogram

  • Electroretinogram may be helpful in treatment and monitoring of retinoblastoma. It may be used for:[2]
    • Monitoring retinal function during treatment
    • Obtaining information about visual potential in pre-verbal children
    • Observing the effect of treatment toxicity on retinal function
