Posterior vitreous detachment
Also written as: PVD — Posterior Vitreous Detachment
Separation of the vitreous gel from the posterior retina, potentially complicating vitreoretinal surgery.
Full Definition
Posterior vitreous detachment (PVD) occurs when the vitreous gel separates from its normal attachments to the posterior retina and optic disc. This age-related process can be partial or complete and may predispose to retinal tears or detachment. In surgical contexts, PVD status significantly influences the approach to vitreoretinal procedures, as incomplete PVD may require induction during surgery to access posterior retinal pathology. Documentation should specify whether PVD is complete, partial, or absent, and note any associated complications such as vitreous hemorrhage or retinal tears that may affect surgical planning.
Usage
Usage note: Specify complete versus partial PVD status in all vitreoretinal surgical documentation.
In Context
- "Complete posterior vitreous detachment was noted preoperatively, facilitating access for macular surgery." — Preoperative vitreoretinal assessment
- "Partial posterior vitreous detachment required careful induction during vitrectomy to avoid retinal damage." — Vitreoretinal operative note
