For a few years, when I go for a long walk my vision has gotten cloudy. Last
Thanksgiving I spent a couple of days cleaning up a tree that fell down.
Afterwards, I could hardly see and, even a couple of days later it hadn't
cleared so I went to the doctor.

They found my IOP was elevated. After a few visits they found the TID's and
the dark ring on the tribicular mesh. A couple of visits later I was
stabilized with Alphagan an Pilocarpine. The problem is that the pilocarpine
screws up everything else. It seems as though my doc and I had a difference
of opinion. I thought she was suppose to keep me seeing; she thought she was
suppose to keep me from going blind from glaucoma. For that reason, I just
changed doctors.

Anyway, the doctors ignore me when I bring up the cloudiness. It's like they
hadn't heard of that or I'm too stupid to understand. I associate it, not
with exercise, but with dehydration. I've been assured that tests involving
people playing basketball verify the exercise connection to pigmentary
glaucoma, but you show me some guys playing basketball, I'll show you guys
going through water.

I have gotten the cloudiness while driving through the Mojave desert and
walking around a horse show on a hot day. No jumping, no running. As soon as
I get out of that environment and have a chance to rehydrate, it gets
better, nearly going away.

A few years ago I had Lasik on my right eye and it was 20/15. Over the last
several months my vision has drifted and I need -1 to -1.5 diopters to get
focused on the mountains again.

Any ideas or comments,

Thanks
Kent

If you get cloudy vision when you pupils are constricted under bright
sunlight for example, and the cloudiness *nearly* go away when the pupils
are more widely open, it is possible that cataract may have developed around
the centre of the lens. If this is the case, any eye specialist worth his
salt should be able to detect the condition.

I did some more experiments. On Sunday I spent the day in the sun and, while
I drank half a gallon of water, I still got dehydrated. But no cloudiness. I
wore dark glasses that also block UV.

That also explains why drinking two gallons Saturday didn't help and going
inside did.

I still think that my earlier explanation of cataract in the center of the
lens fits in with the symptoms you have described, though the part about
drinking plenty of water may be irrelevant.

When the pupil is small constricted because of strong sunlight, the lights
can only pass through the lens through the center of the lens to the back of
the retina. If the lens is affected by nuclear cataract (which is the term
for cataract in the center of the lens), the vision will appear to be
cloudy.

With dark glasses or when you going inside (which I understand to mean
indoor), the pupil dilates. This results in more lights passing through the
lens in portion not affected by the cataract, hence the vision will appear
to be clearer.

The next time you visit the doctor, ask him to check and confirm. I am
curious to know the result.

By the way, it is not advisable to drink a large quantity of water (such as
2 gallons which is about the daily intake) within a short time for glaucoma
patients.

I understand your idea. The problem is that I can spend all morning and part
of the afternoon in the bright sun with no problem. As the afternoon wears
on, I get the symptoms. With your theory, very shortly after I go into the
bright sun without dark glasses, my pupils should close down and I'm in
trouble. This does not happen.

I wondering if my corneas could be getting sunburned.
