Hi,

I notice it yesterday. My iris or the black part of the eye is slightly
lower in
position than the other side. Does anyone know what is wrong with it??
Is it
possible the vitreous get more liquid and the iris simply falls down?
It's small
distance only that I notice it well when I look closer. Pls. let me
know to the
condition asap so I can handle it and not get worry. Thanks.

it is probably nothing to worry about.  relax.
some questions:
is this a recent thing?
are the pupils of different size?
do they both react to bright lights by getting smaller and react to
darkness by getting larger?
have you ever had eye surgery or eye trauma?

yes, it's a recent thing, the pupils are of same size and reactions to
light (dark and light) is good. I don't have eye surgery but trauma...
hmm... when I read too much.. i put my palm and massage my eyes.
Maybe the iris is dislodged??

Just mention if there is any condition that can cause it so I can
research in the net. Thanks.

by trauma i mean have you been injured recently in the area of the
eye-- not eyestrain or rubbing your eyes.

if this is a recent thing, then i would suggest you go to an eye doctor
for a full exam and explain your observations.  i cannot tell you a
specific name to research since there could be more than one cause for
this symptom.  this is not a disease but possibly a symptom of
something else.

No. I have not been injured.

I don't know if it is there before. If a person would look at me, he
won't
notice it. It is only upclose that it is noticeable. When I alight the
bottom
edge of my iris with the lower eyelid. The other iris is lowered by the
size of
a small ant in horizontal position (slight only).

Since I don't have obvious injury. I'm wondering if it is possible that
the
muscles holding the lens are weak in one region causing the lens to
shift in angle and the accomodation to change resulting in slight
repositioning of the iris and eyeball in reference to the other eye.

Could you pls mention what other regions of the eye may be involved.
I'd like to get a theoretical understanding of all possible conditions.

The eyelids are not a good standard for measuring where your pupils are.
Compare the amount of iris above and below the pupil, and to either side.
Normally the pupil is centered, or just a bit nasal.

There are several possible causes for "corectopia" (irregular pupil) and
most of them are benign.

If the irregularity is at the bottom (5:00-7:00), it might be a partial
birth defect, especially if you find it in old photographs.

If it's new, there are several poisons and medications like scopolomine that
can produce an irregular pupil. You might also have what's called "tadpole
pupil," but that's more common in females.

Bottom line - it isn't likely a tumor or an injury, but it's best to get
this checked out if it's new.

It is not uncommon for one eye to be slightly higher than the other.  Or for
one eye lid to be higher or lower than the other.  Or the pupil could be
slightly decentered in one eye compared to the other.  None of these things
are serious  (most are simply anatomical variations) unless you are seeing
double.

The eyeball can change position in the orbit if there is injury to the
orbital bones.  Overactive thyroid disease can also cause change in eye
position but there would also be double vision, weight loss, irritability
and other systemic signs.

,If you think the condition is new (check old photographs for comparison),
you should have an eye exam.
