Non arteritic ischemic optic neuropathy

I lost vision in my left eye last month. I went to Mayo and was told it was NAION. I am still in the learning stage. I don't have any of the risk factors except I have no cup on either eye. My ratio was 10: 0.0 . I am following up with my doctor for a sleep study. I don't think I have sleep apnea but I figure the only way to know is to do the study. How may here have low or no disc to cup ratios?

@naion1lefteye One year ago I had a NAION in my right eye. No risk factors. All bloodwork and MRIs came back normal. Mild sleep apnea. Pulmonologist said I didn’t really need a cpap but I could get one. I chose to, hoping it would help prevent a NAION in the left eye. About 6 weeks ago, I experienced a NAION in the left eye. Again, bloodwork came back normal. Neuro Ophthalmologist ordered another MRI which will be within the next week or so. I also have a small cup to disc ratio but the doctor said “so do a lot of other people and they don’t experience a NAION. Did you ever get answers?

What led your doctor to order a sleep study?
