Abstract

Purpose: To investigate relationship between posterior vitreous detachment (PVD) at the fovea and that in the periphery using spectral domain optical coherence tomography (SD-OCT).

Methods: We studied 40 healthy eyes of 40 subjects (mean age, 70 ± 10, mean diopter of spherical equivalent, -2.5D ± 3.1D with PVD at the fovea. In addition to biomicroscopy and ophthalmoscopy, vertical raster scans (9 mm x 9 mm) centered at superotemporal and inferior temporal vascular arcade and nasal of the optic disc were performed by using SD-OCT (Spectralis, Heidelberg, Germany).

Results: PVDs at the fovea were classified into two types; perifoveal PVD, vitreous attached at the fovea center and at the optic disc, foveal PVD, vitreous detached from the fovea center and attached at the optic disc. Three types of PVD appeared in the temporal periphery, no peripheral PVD outside of the vascular arcade (type A), peripheral PVD with vitreous attachment at the vascular arcade (type B), and peripheral PVD without vitreous attachment at the vascular arcade (type C). In the eyes with perifoveal PVD (26 eyes), the incidence of peripheral PVD was as follows: along the superotemporal arcade, A type: B type : C type = 9 (35%): 7 (27%): 10 (39%), along the inferotemporal arcade, A type : B type : C type = 14 (54%): 5 (19%): 7 (27%). In the eyes with parafoveal PVD (14 eyes) was as follows: along the superotemporal arcade, A type : B type : C type = 14 (100%): 0 (0%): 0 (0%), along the inferotemporal arcade, A type : B type : C type = 0 (0%): 4 (29%): 10 (71%). The incidence of PVD at the nasal side of the optic disc was 9 (37 %) of 26 eyes with perifoveal PVD and 11 (29%) of 14 eyes with foveal PVD.

Conclusions: Various types of peripheral PVDs were observed in the same stage of PVD at the fovea. Types of peripheral PVD may influence on the traction force to the fovea and the vascular arcade, which may induce idiopathic macular hole or epiretinal membrane.
