hey does your eye look like mine
yeah well if it does you might have a
subconscious hemorrhage
and today i'm going to tell you what
that is and what you can
and what you need to do about it i'm dr
michael nelson
and this is good optometry morning
so what is a subconscious hemorrhage
let's break it down into terms so it
talks about the conjunctivity so the
conjunctiva
is the clear multi-layered loose tissue
that sits over top of the white part of
the eye and the conjunctiva has lots of
little tiny blood vessels
that run through it and if one of those
blood vessels breaks
you will get a little hemorrhage hence
the name sub
conjunctival hemorrhage but basically a
subconscious hemorrhage
is a fancy name for a bruise so if you
get a bruise on your arm
or on your leg you get a broken blood
vessel underneath the skin
and it appears black or blue because you
see it through the skin
now when you get one on the conjunctiva
the conjunctiva is clear and so it
appears red
what causes a subconjunctival hemorrhage
i've got the seven most common reasons
for a subconjunctival hemorrhage and i
will list them in order
of the least to the most common reasons
that i have seen in my clinic
so reason number one is some type of
surgery to the eye now this is the least
common reason why i see in my clinic
because usually people can figure out i
had some type of surgery in my
that's probably why i have this little
hemorrhage so this will typically be any
type of surgery
where they make an incision on the white
part of your eye
so this will include any type of retinal
surgery including
injections inside the eye it can also
include refractive surgery because
sometimes the pressure that they use
for some of the instruments can cause a
break in one of the blood vessels it
typically won't happen
in cataract surgery but it can because
cataract surgery usually makes an
incision
right in the cornea where there's no
blood vessels okay reason number two
some type of bleeding disorder
now when most people think of bleeding
disorders they immediately think of
hemophilia but hemophilia is actually
pretty rare
there's actually a more common bleeding
disorder which you've probably
never heard of it's called von
willebrand disease and
basically these conditions are
conditions where your blood does not
clot as easily and so you're gonna be
more prone
to get bruising including bruising on
your eye reason number three
high blood pressure if you have
uncontrolled or higher blood pressure
that's gonna mean that your blood
vessels are going to more likely
have a break in them and cause a little
hemorrhage and so uncontrolled
blood pressure could cause a hemorrhage
like this reason number four
you're taking an anticoagulant or some
type of
medication that's a blood thinner so
most people are taking a blood thinner
because they have some underlying heart
condition or they are at risk for
developing strokes
and so these will slow down your ability
to clot and so you will be more prone to
develop bruising there's a whole bunch
of these blood thinners but probably the
most common one that people are on that
they may not realize is a blood thinner
is a baby aspirin all right reason
number five is related to number three
in blood pressure but basically anything
that can cause a sudden increase of your
blood pressure to your head
can cause a hemorrhage like this so this
can include anything like
coughing sneezing vomiting straining
heavy lifting
anything that will cause a temporary
increase to the blood pressure
could cause a hemorrhage like this
number six is a pretty obvious one
any type of trauma if you get hit in the
eye you are more likely to get some type
of bruise
and number seven and by far this is the
most common reason that i see in the
clinic
of why people get this is under the
category of idiopathic
idiopathic is a medical term for when
some type of condition occurs
but we don't have an explanation why
basically we don't know
but seriously we've ruled out all the
other serious conditions
and we know it's there but we don't
really have an explanation idiopathic
subconscious hemorrhage is probably the
most common reason
that i'll see in my clinic for these
hemorrhages but you need to rule out all
the other reasons
so when we are looking for signs of some
type of eye disease there's going to be
something called a differential
diagnosis
and so what this means is that there's a
list of things that
look like a certain condition but maybe
something else that we need to rule out
and make sure it's not that
so there is a differential diagnosis for
subcontractile hemorrhages
there's a few types of rare tumors
that can happen on the eye that will
look like a subconjunctival hemorrhage
and so when a patient comes in
and so when you go in to get this looked
at your optometrist needs to rule that
out all right so you know what this is
and i've given you a list of possible
reasons
why you may have had this so the
question is should you see your
optometrist
well i would recommend you still go and
see your idoc because it's important for
them to differentiate
some of these rare and more serious
conditions and especially if this is due
to some type of trauma
because an injury that causes a
hemorrhage could also cause a hemorrhage
inside the eye on the retina
or it can cause a retinal detachment or
it can cause some other inflammations
inside the eye that need to be treated
so you've seen your optometrist they've
made the diagnosis
they may have even told you exactly why
this is happening in you
what are you going to do about it well
i've got good news for you because these
usually resolve in about two weeks but
if you take really really good care of
them
you can probably get them to go away in
about 14 days
this is a bruise and the treatment for
it is the same thing
as when you get a bruise for your arm
what do you do you wait there's really
nothing you can do
to make it go away faster you just have
to give it some time and the body
will clear that out okay so i know you
still have a few questions
about subcontract alpha hemorrhages and
i'm going to answer those right now
so if you're taking a blood thinner and
you think this might be related to it
should you stop taking the blood thinner
the answer is absolutely
do not stop taking your blood thinners
unless you talk to your physician first
you have to remember this is a bruise
and this is going to heal up on its own
if you're on a blood thinner it's
probably going to take a little bit
longer for it to heal
but remember the reason why you're on
the blood thinner you're on the blood
thinner
to prevent a heart attack and to prevent
a stroke those are way more serious
than a broken blood vessel all right so
this is gonna bother
everyone else way more than it's gonna
bother you
you're gonna forget about it and you're
gonna get people asking you multiple
times a day
oh what's wrong with your eye what
happened to your eye and you actually
forgot about it and you say oh yeah it's
just a bruise
don't worry about it too much you might
be thinking that yours is getting bigger
and it probably is
the conjugative is a very loose tissue
and so blood can spread
easily all throughout that tissue and
typically what gravity will do
is it'll pull the blood down and spread
it and it'll pull to the bottom and
it'll make it look like the hemorrhage
is getting bigger when in actual fact
it's just spreading to a larger area so
your eye might be a little bit tender
but remember what this is it's a bruise
if you bruise your arm is it a little
bit tender
absolutely is so naturally your eyes get
to probably
feel a little bit tender and a little
bit sore that's a normal feeling
it might even feel a little bit swollen
or a little bit more
full this is not an infection and you're
not
at risk for developing an infection and
as a result you don't need any
antibiotics or eye drops to help clear
this up
so on the topic of eye drops there are
some over-the-counter anti-redness eye
drops
and those will do nothing for this those
medications are designed to constrict or
shrink the blood vessels
to make your eyes look a little bit more
white but these anti-redness eye drops
they won't help the redness on your eye
go away any faster
so definitely don't use them so as this
heals
it's going to change color right now
mine is a dark red color
and that's going to go to kind of a
brown to kind of an orange bronzy color
and then to a yellow as it slowly fades
away so that change in color is a normal
process
this will not affect your vision so so
the conjugative
is not really connected to the cornea so
this hemorrhage can't spread under the
cornea
so it can't interfere with your vision
in any way
so when you see your optometrist they're
going to do a few tests they're going to
check your vision
they're going to figure out with you
what has caused this they're gonna
probably measure the pressure inside
your eye
they may measure your blood pressure
they will give you some advice
on what's causing this and what you need
to know about it but one important thing
to know is
that these shouldn't happen on a regular
basis if if you start getting
subconscious hemorrhages regularly
you should probably see your optometrist
and you should probably also see your
physician
to see if they have a reason why you're
getting these repeated hemorrhages so
