About twenty years ago I went in for this procedure. Doctor used Fluorox drops and Tropicamide Oph Solution .5% in each eye. I had a vasovagal response. Went into anaphylaxis and ended up supine on the floor with three paramedics sticking some sort of paste in my mouth. Rushed to the ER. Was OK a few hours later. Scariest day of my life. My intention isn't to scare off any future eye doctors or students but just have that allergic reaction box on the ready at all times. I felt so bad for the doctor, though. She was just out of school in her late twenties. I remember he calling 911 with a frantic voice, understandably. Great vid by the way.

@user-mw9yd1ix8r Жыл бұрын
Thank you for this very informative video! I was taught that when I have to adjust the dial showing the mmHg, I do it when the prism touches the cornea, so I can see when the semi-circles get in the right position. What is it behind your suggestion to move the prism back and forth doing this adjustment?
@gathorall9136
@gathorall9136 7 ай бұрын
Well you've probably found out since but there's some things for those who don't know. For starters the examples are way off so the movement is too large to make on cornea. Second he is using a disposable tip that isn't quite as smooth as the reusable glass ones. this makes movement and large changes to the dial potentially damage the cornea a bit more. you can still do the fine tuning of the dial like a few circle widths on cornea with a disposable probe, but it is better to get it close as you can off it. So if you've been using a glass probe small movements and mostly dialing on cornea is perfectly fine. But as he's is giving a beginner guide I think he opted for a surefire method for both types to make it simpler and safer, erring on the safe side teaching beginners is definitely a good choice.

No discussion about ghost mires? Also in school I thought you start at 1 and then apply more applanation with the knob, not start at 2 and apply less applanation? 2 would also not be a very common expected pressure, as you said in your video, when the average and normal is 10-21, Unless this is a different type of tonometer? please explain if you can

Thank you for this doc. I recently started working as an ophthalmic technician and im having trouble with this goldmans tonometer. I can't see clearly when I try to look through both sides, that's my eyes fault I guess. I see double vision when I try to look though both sides, however when I try to look through one side, I can see it clearly. I'm nervous because I'm trying to go to optometry school and I know I will eventually have to learn how to use this equipment at both work and eventually school. Any advice? 😭
