N2 - IntroductionIn 2D ultrasound the lens of the fetal eye can be distinguished as white circles within the hypoechoic eyeball, and eye movements can be visualised from about 15 weeks’ gestation. It has been shown that from 31 weeks gestational age the fetal sensory system is capable of directed vision if enough light is available. MethodsWe have developed a light source for delivering visual stimuli to be seen by the fetal eye, using laser dot diodes emitting at 650 nm.
