Abstract
The ultrasound in ophthalmology took an important place, with multifrequency linear probe between 15 to 18 MHz, with higher definition than the old 7 MHz probe. This chapter describes the different types of ultrasound techniques, described the poorly used A-mode echography, and with reference to Color-Doppler ultrasound, and its normal ocular values.
Keywords: Ultrasound, ocular echography, Color-Doppler, ocular artifacts, AMode echography, B-Mode echography.
