I think I understand – you would like to have a small part of the visual field illuminate the retina/sensor. But you would like that part of the field to be off-axis, say in the far periphery. Is that correct?
This is something I have been wanting to implement. It is part of ISETBio, but I have not implemented ISET3d (small FOV but with an arbitrary visual field location). It is something I should do.
Do I understand your problem correctly?

We are seeking to model the photoreceptor activation across the entire retina as a function of angle of incidence of light, and we are trying to determine the best way to do so. From many of the tutorials I have seen, it appears that the field of view is limited to certain segments of the fovea or the periphery, which I have been successful at replicating.
To simulate most of the entire retina, however, I have adjusted the ‘fov’ property on the sceneEye object to a larger number, around 75, and it appears the required memory is well over 100GB. We are prepared to use supercomputing resources, but I wanted to inquire if you had any suggestions on the best way to proceed.
Have you attempted simulating the entire retina? If so, do you recall the processing time? If there are alternatives to simulating without supercomputing, we would be interested in those as well. Our scene is extremely basic and consists of a point light source in front of the simulated eye. For reference, I have adapted my approach from this tutorial: https://www.youtube.com/watch?v=-OCGhhngSCs
We appreciate you reading this message, and would be more than happy to elaborate on our approach if needed.

We are investigating the effect of placement of a light therapy box on photoreceptor activation. For example, how does the photoreceptor activation change across the entire retina when the light box is place 15 degrees in the temporal field as opposed to, say, 30 degrees. So far, I have simply modeled the light therapy box as a point source, so yes, a small part of the periphery illuminates the sensor.
Do you have any suggestions on how to approach this in ISETBIO?
I appreciate the quick response!
