I’m in agreement with Marshall.
However Cyn, there is an iPhone attachment that was made to be able to used
with Slit Lamp oculars. I am not sure if the manufacturer though some others
may be able to help. Then, you would need to use a Rhuby lens in your non
dominant hand.
If the math works out you will be able to use this combination to image the ON
head. Unfortunately as Homo sapiens we have evolved with just two hands and you
would need a third to pull off this maneuver.
There are several light vectors that will require split second calculations
even for the most noteworthy slit lamp officionado’, like Csaba worthy
calculations.
I’d give a month’s training to an RN or PA if they were going to pull this off
in a clinic, or even in the outback/bush like Orbis.
I’d sure like to see the math presented in a scientific session paper though….!

I think you're dealing with two issues here. And in balance you can't have
both: the greater photographic education the user has the more basic the
camera can be.
The less photographically educated would require and more sophisticated
camera.
Just my 2c,

Anyone out there having good luck with a built in smartphone camera that
reliably takes good photos of the optic nerve?
We want this for non Ophthalmology users to take images. The(y) won't want
to work too hard to get decent photos so the camera has to be easy to use
and produce reliably decent images.
