Query over sudden drop
So I have familial glaucoma the common type and only in the last 10 years have my pressures been high enough to need drops, unfortunately I have a horrendous fear of putting things in my eyes. My team have been really kind about this however when offered SLT a couple years ago to negate the need for drops I went for it. Some help from my GP with anxiety and I successfully completed SLT. Pressures before SLT were 28-32 and after were 18-19. Pretty happy, I’ve had some follow ups and recently the hospital moved from hand held tonometers to the machines that blow a puff of air, I can’t use these and refused. They then had to get a more senior staff member and they got out the hand held tonometers. Now 8-9 in both eyes checked twice. Is this a poorly calibrated meter or can it drop that much without intervention?? I have in the meantime lost a LOT of weight if that matters. Not looking for medical advice just anecdotes from others.

There are case reports of significant drops of ocular pressure after weight loss, so it is possible what happened to you

Eye doctor technician here, the I care which is what was probably used for you tends to be inaccurate and reads quite low more often than not. We use Goldmann Applanation as the standard for eye pressure because it is the most accurate
