Can anyone explain

If I have primary angle closure no glaucoma.Have high pressuresAm I correct in saying that the iridotomy I had was to reduce the risk of acute angle closure?

After having it done why did my pressures spike?

Does the pressure reduce? Any idea after how long?

If you have the holes put in to help drain the fluid shouldn't the pressure go down not up?

Sorry for all the questions trying to get to grips with this

Thanks

Hi

I'm not an expert but sometimes the pressure can go up temporarily if pigment has got in the holes or there's inflammation for eg. Did the pressures go back down again? I think there are things they can do like give you drops or even repeat treatment.

Assuming your high pressures raised gradually? Ultimately the goal is to prevent optic nerve damage. High pressures = risk of damage to optic nerves = loss of vision. And they would definitely want to prevent you having an acute attack of high pressure.

I have open angle secondary glaucoma - but following my laser treatment, the holes closed up eventually due to my primary inflammatory disease and they tried a trab instead. That closed up too so finally a tube went in. But I did lose a lot of vision over time because the pressures sneaked up without me being too aware, though I now know, with hindsight, what it feels like: a very dull, heavy ache.

Hope things improve for you.

see my reply to your other post. Yes, iridotomy opens your angles and reduces the risk of acute angle closure. Which I’ve had in both eyes and it’s incredibly scary. I don’t think they fully understand why the pressure spikes after the procedure but it’s not uncommon which is why they ask you to wait and check after an hour. The medication should bring it back down. - the spike is usually only temporary.
