Hello Johnson12,


If your mothers IOP was 45 it could be that she has narrow angles. This means that even though the eye is producing the Aqueous Humour to keep the eye healthy with all the nutrients it needs, it does not flow out of the eye as well as it could do (a bit like a blocked drain) which can cause the pressure to rise. There are normally warning signs if the Intraocular pressure (IOP) is rising. It could halos around light, extremely bad headaches and also feeling sick. When this happens, damage can be quick so the patients needs to get to the A & E department as soon as possible so they can be treated to bring the IOP down to reduce the risk of anymore damage.

Having cataract surgery tends to open the drainage system even more and in turn helps reduce the risk of another spike in pressure. There is a paper called the EAGLE study which shows that people who have narrow angles can benefit from having lens replacement surgery even if there are no signs of cataracts.

A spike in pressure after cataract surgery can sometimes happen but this is dealt with quickly to bring the pressure down. When this happens it does not mean that glaucomatous damage will occur.

Any concerns should be discussed with your mothers consultant.

Hi.  I'm only a patient, not a medic, but I'd say, Not necessarily.  After any eye op a patient is likely to be given steroid drops to help healing and they tend to raise the eye pressure - more in some people than others, so that probably happened after the cataract op.  If the docs were worried that the rise was permanent after that op they would have been checking your mum out before now, but her pressure returned to normal. The aqueous drains out through a meshwork and for whatever reason that stops working so efficiently - in my case due to inflammation.  The body continues to make aqueous, so too much builds up, can't drain and you get high pressure.  Some people develop glaucoma due to the shape of their eye... there are many different causes and types of glaucoma.  The pressure is measured on the same scale as a barometer, whatever scale that is.  I had many years of glaucoma in one eye, then finally we tamed it with a tube.  As soon as that happened, the pressure started to rise in the good eye.  Why? Don't know.  It had never shown any sign of a problem during the 35 years of hassle with the first eye.  The first eye is now awaiting a cataract op... nothing abnormal about that, I'm now 70.  I think it is very often difficult to pin down cause and effect in glaucoma cases.... some people just seem "due to get it".  The most important thing is to get it under control as soon as possible.  What was right for my eye may not be what should be done for hers... the specialist will consider all options.  Good luck to you and your mum!

Hello, dear colleagues!

I am new here, on the request of my mom, who was diagnosed with glaucoma recently, one eye.

However, my question is related to the cataract surgery and the possibility that due to this surgery the operated eye pressure could jump and cause the glaucoma in that eye. I know a bit about how the hydrodynamics of the eye works, how the cataract surgery works and, personally, I think that the surgery could have perturbed the flow of liquids in the eye. Am I right or wrong or in between?

Some details. Recently an eye blood vessel exploded and, with the red eye, she went to see her clinics, where the glaucoma was diagnosed and the eye pressure was high uopn the measurement. The doctor said, glaucoma surgury was to be considered. The eye pressure 45 (in I do not know what units) and the eye drops have reduced this pressure to 22 (in two weeks time). I do not know more so far. Save that she had the cataract surgery 2 years ago and there was a complication related to a sharp increase in the left eye pressure. She was treated with eye drops for a couple of weeks and the pressure had decreceased and had been normalized. However since then she has not shown her eyes to her ophtalmologist till recently(see above).

So can, the cataracte surgery block the liquids flow in the eye to the extent that the pressure becomes anomalously high? And it goes on being high and the eye nerve gets "glaucomic"?

Kind regards to all of you,
