Retinoblastoma


I had a very interesting telephone consultation about a pregnancy. The father had a history of Retinoblastoma. On genetic testing the child had a deletion in the Retinoblastoma Gene.

The question was if there was any thing to do. They already decided not to abort.

Retinoblastoma can develop during pregnancy. I have seen the ultrasound of one of my patients showing the fetal eye full of tumor. On the other hand, many of the hereditary cases I have seen do not have much tumor at birth. We get generally better results treating smaller lower group tumors. So the first question is how to detect the tumor. The choices are high resolution ultrasound or fetal MRI

What to do?

Consider an early birth at 36 weeks, the chances of premature complications are very low and this will allow a better chance of normal visual development and retention of the eye.
