Gas bubble positioning after vitrectomy helps keep the bubble pressing on the treated area of retina while it heals. Following positioning instructions carefully is critical for surgical success.
Common Positioning Instructions
Different conditions require different head positions.
- Face-down or specific side-lying postures may be recommended to support macular holes or retinal tears.
- Patients are often asked to maintain the position for much of the day, with short breaks, for several days or longer.
- Written instructions clarify how long positioning is needed and when it can be reduced.
- Special equipment, such as face‑down chairs or cushions, can make this more manageable.
Safety Considerations
Gas in the eye affects other aspects of daily life.
- Flying and travel to high altitude are strictly avoided until the gas has fully absorbed.
- Certain anaesthetic gases are unsafe while intraocular gas remains; patients should carry an alert card.
- Sudden severe pain, vision loss, or a marked change in the bubble’s appearance should prompt urgent review.
- Clinicians confirm when the gas has gone and normal activities can resume.
