Evolution of Early Changes at the Vitreoretinal Interface After Cataract Surgery Determined by Optical Coherence Tomography and Ultrasonography

摘要

EDITOR: WE RECENTLY REPORTED ABOUT THE PREVALENCE OF posterior vitreous detachment (PVD) after cataract surgery. The study showed that uneventful phacoemulsifi-cation in eyes with complete vitreoretinal attachment induces some degree of PVD in 71.4% within 3 months after the surgery. The status of the posterior vitreous cortex (PVC) was evaluated with both optical coherence tomography (OCT) and ultrasound. PVD was classified further in stages. Accordingly, stage 1 was defined as perifoveal detachment of PVC in 1 to 3 quadrants of the macula; stage 2 was defined as PVC detachment in all quadrants with persisting attachment to the fovea and optic nerve disc; stage 3 was defined as complete detachment of PVC from the macula and optic nerve disc, but remaining attachment to the midperiphery of the retina; and stage 4 was defined as complete vitreoretinal detachment from the posterior pole.
