Sidney’s eyesight is much worse today than it was two days ago. So the optic nerve was damaged when the pressure was high yesterday. Normal pressure is 4mm hg, yesterday was getting readings in the region of 65-67mm. After the needle in the eye it reduced to below 10mm. We had been told to watch out for pupil dilation and sadly his pupil is very dilated which could indicate the pressure is rising again - at which point the pressure reducing eyedrops don’t work as they can’t get into the eyeball.
His eyesight has been deteriorating over the past few years but todays walk (on a lead) showed it has got much worse. He can see large objects but no detail, and was walking into twigs and tall grasses repeatedly.
If the pressure is elevated tomorrow when we see the eye vet again it may well be time for the tough call to remove his one eye. Then we will have to make sure his quality of life is good, that he is happy and not anxious or depressed.
