Objective To evaluate the features of position and morphology of stage 1 posterior vitreous detachment (PVD) in young adult myopes. Methods In a prospective case series study, a total of 305 young adults (607 eyes) with myopia, posterior vitreous detachment was examined under 2D and 3D images by optical coherence tomography. Results There were 141 eyes at stage 1 PVD. The percent of PVD located within one, two or three quadrants was 26.95%, 59.57%, and 13.48%, respectively. In 24 eyes (17.02%) there was a tendency for PVD to be located in the superior quadrant. But the inferior, temporal or nasal quadrants were also the original quadrants of incomplete PVD. And the PVD in two different quadrants could not form a connection. The morphology of stage 1 PVD was V-shaped in 2D images and dish-shaped in 3D images. Conclusion Not all PVD in young adult myopes started in the superior quadrant. The initial stage of PVD was V-shaped and had multifocal traits at times.
