If you are still searching for other areas that can be a valid reason for having problems with sleep apnea, chances are you better have your eyes checked. Based on a study, eye disorders have a bearing on obstructive sleep apnea which includes:
1. Floppy Eyelid Syndrome
2. Glaucoma
3. Nonarteritic anterior ischemic optic neuropathy (NAION)
4. Papilledema
The relationship between eye and sleep disorder really makes sense. Just imagine the issues it brings to your brain which is related to sleep. Also, our eyes can become a problem if they are not in the relaxed state that makes them less to worry about especially when we are in a sleeping state.
If you want to discount that possibility, see an Ophthalmologist to be sure. At least you can cover one area and discount it in the end.
