I would just eyeball it. Then I would suggest the resident come up with a more
interesting article topic.

Ext Mail: open links/attachments w/caution Better question- why? Is this for
research? Not sure what clinical application measuring a gas bubble would be
useful for. Almost everyone I know subjectively measures it- ie; “40 percent
gas fill”, etc.

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
