Prognostic Value of Hemodynamic Disturbances in Rhegmatogenous Retinal Detachment (CRADO-RED)

Prognostic Value of Hemodynamic Disturbances of the Central Retinal Artery in Color Doppler Ultrasound in Rhegmatogenous Retinal Detachment

Retinal detachments correspond to a separation of the neuroepithelium from the pigment epithelium. They can be exudative (sometimes in conjunction with a tumor), tractional, traumatic (postoperative) or rhegmatogenous (in relation to a tear).

Ultrasound, requested when the fundus is difficult to achieve and shows a hyperechoic mobile membrane. It can also measure the hemodynamic parameters of retinal arteries.

A preliminary study showed a correlation between systolic velocity in the central retinal artery and postoperative visual acuity.

The aim of this study is to confirm those preliminary data.
