How Close Can We Look Into the Fetus by New Applications of Three‐Dimensional Ultrasound: The Fetal Eye

Three- and four-dimensional ultrasound technology has become essential in the field of prenatal diagnosis. Recent exponential improvements in ultrasound machines and 3D technology have produced high-definition, high-resolution images, and new rendering modalities have opened up novel perspectives for exploring fetal anatomy. This raises the questions about how detailed our examination of fetal anatomy can be and what clinical applications remain undiscovered. This short article aims to provide academic references focusing specifically on examining minute structures within the fetal eye using advanced 3D ultrasound technology.
