Retinal detachment surgery: urgency, gas bubbles and flying

What is retinal detachment surgery?

MedlinePlus describes several ways to repair a detachment caused by a hole or tear in the retina. Every repair has two parts: closing the break and creating a scar around it with a laser or a freezing probe.

• Laser or freezing treatment can seal a tear before the retina detaches
• Pneumatic retinopexy places a gas bubble in the eye and positions your head so the bubble presses the retina back
• A scleral buckle indents the wall of the eye inwards to meet the break
• Vitrectomy uses fine instruments inside the eye to relieve pulling on the retina so it can settle back
• Complex cases may combine a buckle and vitrectomy

MedlinePlus says most vitrectomies are done under local anaesthesia, while some procedures need general anaesthesia. Most patients do not need an overnight stay.

Who may be suitable for which repair?

The choice depends on the size and number of breaks, whether scar tissue is present and whether the macula, the centre of the retina, is involved. MedlinePlus notes that pneumatic retinopexy is mainly used when the retina has only just begun to detach. A vitreoretinal surgeon chooses the method after examining the eye. Some people need more than one operation.

What reports does a retina surgeon ask for?

If you are seeking a second opinion or planning further surgery, the surgeon will want a clear history. Useful items include:

• The date your symptoms began and when the macula was found to be affected, if known
• Operation notes from any earlier repair, naming the method used
• Whether gas or silicone oil was placed in the eye and the date
• Retinal scans and photographs, such as OCT images, with the original files if possible
• Your latest vision and eye pressure readings
• A list of medicines and other eye conditions

How should you plan travel around this surgery?

MedlinePlus is clear that people with a gas bubble in the eye should avoid flying or travelling to high altitudes until the bubble has gone. Expanding gas at altitude can damage the eye. This shapes every travel plan.

• If you already have gas in the eye, do not fly until your surgeon confirms it has cleared
• If gas may be used in India, plan to stay until your surgeon confirms it is safe to fly
• Ask about head positioning. MedlinePlus says after a gas repair you may need to keep your head face down or to one side
• Bring an attendant who can help with meals, drops and positioning
• Arrange a review with an eye specialist at home and carry your operation notes

Hotels can often help with simple support for positioning, such as extra pillows. Ask your case manager to arrange accommodation close to the hospital.

What should you ask the eye hospital?

• Which repair method do you recommend for my eye and why?
• Will you use gas or silicone oil, and when will I be able to fly?
• What head position will I need to keep and for how long each day?
• Will a further operation be needed, for example to remove silicone oil?
• Who will check my eye pressure after surgery?
• Can you send full notes and scans to my eye doctor at home?
