Maybe it won't be possible... the doc wants to assess gas fill using
different gasses and concentrations to see which is best for achieving
complete fill in the post op period day one.

No idea how I’d image this or even try. Sounds like a bit of a wild goose
chase….

You would take the average of the appearance of the bubble on an Optos
image. It would have to be an average of L vs H and converted to mm.
Then, using volume of a sphere formula of V= 4/3 pi x radius cubed. I
would start there.
My sources would include Mr Bennett and Mr JHawkins - you guys have
anything on this?

Alan,
Speaking as a two-year post op mac hole patient, that would be
interesting. 😊
I think you would need a very wide-angle view.
The first few weeks the doctors does not want you to do anything but look
down.
I lived and slept for weeks on a borrowed massage table.
Eating and doing my drop regiment were the few exceptions.
Initially I could not see the edges of the gas bubble, as it was so
large. I can’t remember the timing but after several days I could see an
edge when I sat up.
I think it was another few weeks before I could see the smaller bubble
that remained.
I rode to the eye doctor and sat in the waiting room with my head down
several times for follow-up exams and hoping that I was done with the head
down phase of recovery.
After thinking about this as I write possibly ultrasound might be a better
modality because of the bubble size and positioning.
Denice, what are your thoughts?

Hi, I have a resident who, on post op mac hole patients, would like to
objectively measure the gas fill by imaging.
Does anyone have any thoughts on how to attack this?
Thanks,
Alan
