Abstract

The ultrasound in posterior segment pathologies is the gold standard examination technique in cases of media opacities, when a cataract or vitreous hemorrhage exists. The first technique used to visualize the posterior segment is the echography. The ultrasound examination is fundamental in retina pathologies as retinal detachment in patients with cataracts. Its importance has been increased with the introduction of color Doppler echography which helps us in vasculophaties as arterial or venous occlusions or in patients with diabetic retinopathy. Furthermore, echography is useful in postoperative vitreous-retina patients, to detect new retinal detachments or peripheral new vessels growth in cases of recidivant hemorrhages.

Keywords: Vitreous echography, retina echography, choroid echography, scleral ultrasound, retinal detachment, vitreous hemorrhage, diabetic retinopathy, uveitis echography.
