just to post my experience, I have had a Retina Detachment in my left eye, which after reattachment surgeries still has poor vision and color recognition. in my medical exam, i was to pay extra to get my eyes examined specially by an ophthalmologist, who drew up a report for CIC, he didn't share the report.
up till now while i havent gotten my PR, my medical was cleared, around the same time, as others in with my AoR.
