Mae’r Pwyllgor Sgrinio Cenedlaethol yn argymell cynnal archwiliad corfforol ar blentyn adeg ei eni a phan fydd yn 6 wythnos oed er mwyn canfod cataractau cynhenid, dysplasia'r cluniau, namau cynhenid ar y galon a cheilliau cudd yn gynnar. Argymhellir yr oedrannau hyn ar sail arferion gorau a thystiolaeth bresennol, a dylai’r babanod wedyn gael eu hatgyfeirio’n brydlon am asesiad clinigol cynnar.
Physical examination of a child at birth and at 6 weeks is a National Screening Committee recommendation for early identification of congenital cataract, hip dysplasia, congenital heart defects and undescended testes. These ages are recommended on the basis of best practice and current evidence and should trigger a prompt referral for early clinical assessment.
