How can I differentiate between Congenital cataracts and retinoblastoma?

Well, only in case of bilateral white reflex, its Cataract as its very unlikely for retinoblastma to be bilateral, as for unilateral, its retinoblastma untill proven otherwise


  #3

i guess detailed family history and mothers OB history wud help ... any infections during pregnancy varicella , rubella ... .

family history of any genetic disorders in family ( galactosemia) ....

The MOST COMMON cause for the white reflex is Cataract while THE MOST DREADED one is Retinoblastoma.


  #5

RULE::::if there is white replex present first thing is to check for retinoblastoma most dreaded thing to rule out...and then cataract comes.

Ok.
If the Qs doesn't say about Hx, should I have to stick with "cataract" because it is most common one.
And I'll answer "Retinoblastoma" ..... When?
Retinoblastoma 25% is bilateral.
... I don't get it yet. confused
Could you explain it a little more, pls.
