AbstractPosterior vitreous detachment (PVD) is a separation between the posterior vitreous cortex and internal limiting membrane. Although PVD was historically considered an acute event, recent studies using spectral-domain optical coherence tomography (SD-OCT) revealed a gradual progression of PVD in healthy subjects. Although SD-OCT improved PVD studies, the narrow imaging angle and long examination time were problematic to allow wide angle capture. The Xephilio OCT-S1 (Canon), a swept-source OCT (SS-OCT) device, can obtain up to 23-mm of widefield B-scan images in a single acquisition. We used this widefield SS-OCT to quantitatively evaluate the PVD stage in 214 healthy subjects aged 4–89 years and determine whether PVD stages differ between the bilateral eyes of each patient. Age was significantly positively correlated with the overall PVD stage (ρ = 0.7520, P < 0.001). Interestingly, partial PVD occurred in children as young as 5 years, indicating that initial PVD onset may occur much earlier than previously reported. Furthermore, PVD stages of the bilateral eyes were highly consistent in 183 subjects (85.5%). Widefield 23-mm SS-OCT thus revealed that PVD started earlier than anticipated, and age was correlated with the symmetry of PVD stage. Widefield 23-mm SS-OCT may also be clinically useful for the evaluation of diseased eyes.

Optic Disc Pit Maculopathy

Purpose: This work presents a case of significant improvement of optic pit disc maculopathy following an acute posterior vitreous detachment (PVD) and discusses the possible mechanisms of this phenomenon. Methods: A case report and review of the literature are presented. Results: A 56-year-old man presenting with progressive visual decline in his left eye was found to have an optic disc pit with optical coherence tomography (OCT) evidence of severe intraretinal edema and maculoschisis. His visual acuity and macular anatomy on OCT improved dramatically in the months following a PVD. Conclusions: This report presents an interesting case of spontaneous improvement of optic disc pit–related maculopathy following PVD. We discuss the cause of the retinal fluid accumulation in optic disc pit maculopathy and consider that the OCT findings in our case lend credence to the theory that this fluid originates from the vitreous humor.
