Im still thinking about this...
Was going to Google "punctal plug", but I didn't. Realized that it sounds like puncture plug... started reminiscing my eye injury, I was hit in the eye with the hook of a bungee cord(fully extended and slipped), could only see white with blurs for days. It hurt and light made it worse. Couldn't see anything. The eye doctor tried dilating my pupils to inspect the retina. They didn't/ He couldn't, but the drops relieved the pain and helped focus the blur. He explained how the white part of the eye is a muscle, filled with fluid that keeps the retina pressed against the back of the eyeball, and mine had a Charlie horse, it also lost fluid/had "low pressure" from the impact, so the drops relax the muscle to dilate the pupil(explaining why it felt better).[remembering you mentioning dilation/punctal plug- pondering relevance] I had a detached retina and I refused the surgery. For 2 years, I saw non existing movements/ lights from that eye. Most the times it looked like a flashlight shining (a 1/4 circle @) the wall, at its worse- I would walk into the house and it was lighting struck the couch in front of me, enough to get your heart pumping/ full adrenaline response (so intense I would have to sit down and regain composure). It was hard to not be able to trust what you see with your own eyes, it was scary to realize how quickly/seamlessly my brain abandoned that eye. I found myself driving with my head turned to center the right(good) eye. But it's 99% better now(don't think I should go on a roller coaster though).
I lost track of where I was going with this but I hope it's as coherent as I thought. In my head, reading this makes you feel better :grimacing-face:
