What is a vitrectomy
Vitrectomy involves the removal of the vitreous gel, a clear substance that fills the inside of the eye. This gel is normally attached to the retina and can contribute to traction in retinal detachment.
Removing the vitreous allows the surgeon to access the retina directly and eliminate forces pulling on it.
How vitrectomy works
Once the vitreous gel is removed, the retina can be repositioned. Any tears or breaks may be treated, and a gas bubble or silicone oil is introduced into the eye to support the retina while it heals.
This internal support helps keep the retina in place against the underlying tissue.
When vitrectomy is used
Vitrectomy is often used in more complex or extensive retinal detachments. It may be recommended when there is significant traction, multiple retinal breaks or when other approaches are less suitable.
It is also commonly used when central vision is at risk.
The procedure
Vitrectomy is performed in a controlled surgical setting using specialised instruments. Small openings are made to allow access to the vitreous and retina.
The procedure is carefully planned based on the individual characteristics of the detachment.
Recovery after vitrectomy
Recovery depends on the extent of the detachment and the specific procedure performed. If a gas bubble is used, specific head positioning may be required to ensure proper retinal support.
Vision may be temporarily affected during recovery and can improve gradually over time.
Post-operative care
Follow-up is essential to monitor healing and ensure the retina remains attached. Patients are given specific instructions to support recovery and reduce the risk of complications.
Detailed overview of what recovering vitrectomy patients should expect following the surgery, including pain, discomfort, and decreased vision, and discusses follow-up medications and the use of protective shields. Notes estimated recovery times, and what activities are should be limited or avoided during the recovery period.Expected outcomes
Vitrectomy is effective in reattaching the retina in many cases. Visual recovery depends on how quickly the detachment was treated and whether central vision was affected.
Early intervention is associated with better outcomes.
