I have had ocular hypertension for about 25 years, treated with drops.I
just had a full eye exam with full dilation and my first corneal
thickness measurement, by a Pachmate device. I was happy that the
cornea is thick,with the suggestion that my eye pressure can be
considered four points below the IOP measurement.
An hour after I left the office, I felt pain in the outer right eye and
there was sbleeding. The pain resolved soon, and the blood residue is
gradually getting absorbed. When I called my glaucoma doc, he said to
use an antibiotic drop and see him after the weekend. The eye then
looked OK to him; it was not scratched.
He asked if I have hypettension ( am on Dyazide & BP is not high) or was
on Motrin, aspirin,etc., or had rubbed it.(No.) Since the event came
spontaneously, I wonder if there could be any connection to the pupil
dilators or the Pachmate, which I believe touches the eye.
I did have a similar unexplained event in the left eye a year or twoago,
which resolved. At that time, the same Dr. just said to use sterile
water on the eye.
Any thoughts, for future reference. If it could be the Pachmate, I think
the experience shouild be made know to hte manufacturer.
Thanks!

Corneal pachymetry machines all work by touching a probe to the cornea
gently to determine the corneal thickness using ultrasound. There is
no contact with the probe and the conjunctiva, the membrane over the
white of the eye that has blood vessels. It is therefore impossible
for the pachymeter to have caused a subconjunctival hemorrhage. If the
probe accidentally grazed the conjunctiva (by technician error) or if
you rubbed the eye this could have occurred. Also, yes, medications
that thin the blood could be implicated, as could anything that raises
blood pressure a bit (straining at lifting something, constipation,
holding your breath, sneezing, coughing, etc.)...and...sometimes these
things JUST HAPPEN. It is absolutely nothing to worry about.
Subconjunctival hemorrhages always go away on their own and never hurt
the eye. Take care,

Dear Dr. Rick Cohn ("Eye Guy")
Thanks for the concurring opinion..I was confident that you would be
informative and reassuring. I now believe that these things really can
"JUST HAPPEN." Thank you!
You've been so helpful each time. Again, I wish that you practiced in NJ
>"< Is there a way to make a small contribution to your practice, in
appreciation? Just let me know..
With appreciation,
Carolyn

That's very sweet, Carolyn...it's my pleasure to help out. As for my
practice, the only contribution I usually accept is baked goods,
especially those with chocolate! I'm not sure how brownies would keep
in the mail. Of course, if you ever wanted to make a charitable
contribution in my name, I would be grateful. I just found a wonderful
website called "charitynavigator.org" which rates charities, I guess by
how well they fund raise and by how they distrubute their money.
Unfortunately, the Glaucoma Research Foundation was rated quite low.
Several guide dog foundations were rated well, getting 3 out of 4
stars. I think giving toward the training of guide dogs is a very
noble cause. Anyway, it was very nice of you to offer, and anything
you do would be very much appreciated.
Take Care,
Rick Cohn, MD
