简要总结
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.
