Quantitative evaluation of the point of vitreous detachment perpendicular line to the macula (PLM) indicated by a white solid line is assumed to pass the minimum distance from the center of the fovea to the choroidal line indicated by a white dot line. This is a tangent drawn to the outer border of the retinal pigment epithelium at the bottom of the foveal center. The distance of PLM to the point of vitreous detachment (white arrow) (PLM-VD) is measured for PVD staging. In this case, the temporal PLM VD (*) is 2568 µm, and the nasal PLM VD (**) is 1802 µm, both larger than 750 µm; therefore, the diagnosis is PVD stage 1.
