In clinics, we often observe different measures of IOP in myosis vs midriasis. What do you think about this procedure and why?
Of course it is a peculiar question. I'm asking why IOP should be lower and not higher.
It is a good question. Les see how ophthalmologists respond to this one.
I would personally request Dr, Hasnain to give his opinion.

1. Acute phacomorphic glaucoma. Mydriasis will break a pupillary block and push the lens-iris diaphragm posteriorly.
2. Neovascular glaucoma and inflammatory glaucomas. By reducing the inflammation.
3. Hyphema with high IOP. Mydriasis will prevent blood clot dislodgement, control inflammation & lower IOP.
I forgot to add that I've found this in young boys in routine clinical practice. The had normal anterior segment. Any explanation?
I think the causes are both mechanic ( pupillary block ) and / or vascular ( ciliary body iperactivity in sustained accomodation ). The last observed cases were young boys coming at my observation after mobile phones using in the waiting room. Beside accomodative myopia they had an abnormal IOP. I'm going to check further this findings. Several papers have been written about the possible link of peaks of the IOP with myopia progression even if they didn't find a clear association. I hope to design a study to disclose this question also.
