My own recent experience treating an eye problem with the Micro-pulse M1 and my review of other posts on eye conditions both suggest starting with the lowest intensity setting and keeping close track of both benefits and possible side effects (sometimes called healing crises, detox reactions, etc.). The problem I have been dealing with is floaters. Initially, I was getting headaches after applying the coils close to or directly on my eyes. @Bob has a theory that this may be related to pressure changes in anatomical cavities as inflammation decreases. That makes a lot of sense to me.
Interestingly, the headaches would not generally be in the same location where I applied the coils. In fact, they were often in the occipital region of the back of my skull, which is associated with vision in traditional Chinese medicine. I could reliably treat the headache by using the M1 directly on the acupuncture points in that area. It’s almost as if pressure was released from one area (in the eyes themselves) but stagnated in another section of the associated acupuncture channel, which then required direct treatment itself. Or, I should say the headache was resolved rapidly when direct treatment was applied to the local area. I suspect it would’ve resolved on its own anyway. I haven’t had any headaches since I switched to using the lowest intensity setting, although it may be a coincidence. It may be that the inflammation was largely resolved and the pressure in my skull largely equalized by the earlier treatments and so I was no longer experiencing the “side effects.” As things are going well for me right now, I’m not really willing to experiment with a higher intensity setting to test the hypotheses.
I’ve also had a couple experiences that lead me to believe that putting the coils directly on my eyes even at the lowest intensity setting may temporarily aggravate the floaters. My floaters are due to what is called posterior vitreous detachment. As I understand it, there are strands of the vitreous gel floating in my eyeball. It is generally thought that the symptoms of PVD will resolve spontaneously over a few months as the strands of gel settle in the lower portion of the eye and no longer pass through the field of vision. However, as they are still currently “floating,” it makes sense to me that applying a stimulus directly on the eye might be analogous to lightly jostling a bowl of still water with a little bit of sediment in it. Further confirmation that this may be what is happening is that when the acute exacerbation of the symptom occurs, it typically resolves within about 15 minutes. Just as a jostled bowl of water would eventually settle down if no further stimulus was applied to it.
