Hi ter0624 and welcome to the forum.
Your eye pressure, with your drops, is actually in the low normal range. And your CPAP treatment pressures are thankfully on the lower end of things. The 2007 study that got glaucoma patients all frightened over CPAP treatment involved 21 OSA patients being treated with CPAPs at a great variety of treatment pressures. These patients were sleeping in various positions, but all lying flat in bed (the supine position is known to raise IOP - intraocular pressure). The researchers themselves indicated that one couldn't draw firm conclusions from such a limited study and recommended that more research be done with a much larger pool of subjects gathered worldwide. Strangely, no such follow up studies seemed to have happened to date. One must contrast this with the tremendous pool of studies that exist linking OSA to glaucoma. People with untreated OSA are ten times more likely than those without OSA to develop glaucoma over their lifetimes.
Research studies all around the globe have demonstrated the association of OSA with glaucoma. What's really interesting is the finding that this association isn't because of IOP changes or changes in chest pressure. Instead, it's most likely caused by the drop in oxygen levels in the blood, which happens when you stop breathing. Routine low oxygen concentration in the blood may contribute to degradation of the optic nerve - potentially leading to glaucoma. This is the current hypothesis.
Healthcare providers have decided to err on the side of caution. They wholeheartedly recommend CPAP as the first, most effective and least invasive treatment for OSA, but throw in this caveat for those with glaucoma...that they get regular IOP screenings every 3 months and ophthalmic check-ups, which is what your caregivers are doing. I really wouldn't worry about your CPAP causing you any harm. You're going to be followed for that. You're going to be OK.
Weight loss has many benefits, but it's not a "cure" for OSA. OSA is a moving target that usually worsens over time, with the occasional seasonal illnesses and as some other chronic health conditions come home to roost. Deciding that your apnea is better is not a good reason to stop CPAP treatment. I don't think I would stop CPAP unless I had another sleep study that proved my untreated AHI (Apnea/Hypopnea Index) was under 5.
Do you have a copy of your sleep study? If not, by all means go get one. You're entitled to it. Consider getting the Sleepyhead application (available for free online) so that you can review your own sleep data on a daily basis. What you learn will amaze you as you see for yourself how your CPAP treatment "saves" you each night. You'll find out if your mask is leaking too much. You'll be able to troubleshoot, with others here on the forum, how to make your CPAP treatment even better and even more comfortable.
So...have at it, friend...and the sooner the better.
