Update on Retinal Displacement Following Surgical Repair of Retinal Detachment

Abstract

Retinal displacement following surgical repair of retinal detachment is a common complication. It involves the repositioning and fixation of the retina in a non-optimal area. Associated risk factors include pars plana vitrectomy as a surgical technique, the use of gas as a tamponading agent, or a retinal detachment involving the macula. Among complementary diagnostic tests, autofluorescence plays a pivotal role, revealing the presence of retinal vessel imprints through the depiction of hyperautofluorescent lines that run parallel to the vessels. These lines represent the original vascular pattern and serve as a distinctive hallmark. Despite the surgical repair of retinal detachment, there is a high incidence of metamorphopsia and visual dissatisfaction among patients suffering from retinal displacement. Several approaches have been proposed to reduce retinal displacement, including the use of a smaller gas bubble as a tamponade, immediate placement of the patient face-down in the operating room, and maintaining this position for at least 2 hours after surgery. In this chapter, we will elaborate on these aspects based on recent literature.
