The following text was provided by one of our forum members
(Sweet) who is a nurse and has recently completed a teaching session at
work as part of her training, aimed at nurses based on the two most common
eye complaints presenting to 'A & E',
being
foreign bodies, and conjunctivitis.
Most
of us have attended an accident and emergency department at some point with
an eye problem, typically due to KC and contact lenses!
Here is the second part of Claire's teaching session
after foreign bodies.
I hope you find it helpful!
Conjunctivitis
Conjunctivitis is
an inflammation or infection of the conjunctiva, which is the thin, clear
membrane over the white part of the eye and also the lining of the eyelids.
It's common name 'pink eye' relates to the pink or red colour the affected
eye has which is due to inflammation.
This condition can be triggered by
a virus, bacteria, allergic reaction (to dust, pollen, smoke or some chemicals),
or as with giant papillary conjunctivitis, to a foreign body, (typically
a contact lens).All forms of conjunctivitis can cause the same symptoms
with the eye becoming inflammed causing it to hurt or itch. The exact cause
is needed to ensure the correct treatment, with viral and allergic conjunctivitis
being the most common.
Viral
conjunctivitis
Usually affects one eye but can spread easily to
the other. It causes excessive eye watering with a light discharge,
and the eye may also sting or cause a lot of irritation. This form
is often associated with an upper respiratory tract infection, cold
or sore throat and can be spread rapidly. |
Bacterial
conjunctivitis
Usually affects both eyes though normally starting
with one and spreading rapidly to the other. There may be an irritation
or gritty feeling in the eye with a stinging heavy discharge,often
green in colour, which may cause eyelids to stick together when sleeping.
The severity depends on the type of bacteria, usually staphylococcus
or streptococcus (just so you know!) which typically orginates from
patients own skin, an upper respiratory tract infection, or from someone
already suffering with the condition. |
Giant
papillary conjunctivitis
Usually affects contact lens wearers and both eyes
causing itching, a heavy discharge, tearing, red bumps on the underside
of the lids and an intolerance to contact lenses. |
Allergic
conjunctivitis
Usually affects both eyes causing itching and redness,
which sometimes includes the nose, swollen eyelids and excessive tearing.
It is normally seasonal and occurs more frequently among those with
allergic conditions or hayfever, asthma and eczema. It may also be
associated with an intolerance to cosmetics or perfumes. |
Treatment
If left untreated most cases
of conjunctivitis will get better in a few weeks. Gaining treatment however
will speed up the process, aid comfort to the affected eye(s), and hopefully
lessen the risk of infecting others.
- Viral
- As there is no cure, medication is not
normally prescribed as antibiotic treatment is not needed. Cold
or warm compresses may help, as well as some lubricating eyedrops to relieve
any discomfort, (I'm sure that we know all about these!)
- Bacterial
- Usually treated with antibiotic
eyedrops or cream to clear up any infection such as chloramphenicol.
Regular eye cleansing using cool boiled water is often needed
with heavy discharge.
- Allergic
- Mild
cases may only need cool compresses although anti-histamine (to reduce
itching) medication or eyedrops can help control some of the symptoms.
Persistent cases may need anti-inflammatory or topical steroid drops, (to
reduce inflammation). In severe cases it is better to avoid
any known allergies by staying in well ventilated rooms and keeping
windows closed to try to reduce potential allergens at home.
- Giant papillary
- Normally
affecting contact lens wearers so will need to remove these for a short period
of time until seen by a doctor. (Now we are blind!). May need to replace
lenses with new ones or change to a different type of lens, such as from
soft to gas permeable, or indeed ones that you change regularly such as daily
disposables, (Not so sure that most of us here will have a choice with this!)
Avoidance
Avoiding the cause is
the first line of defence to avoid re-infecting yourself or others. there
are many tips to avoid spreading the condition, as conjunctivitis can be
passed very easily around school children and families. The following are
a few guidelines to use with an eye infection.
- Wash your hands frequently,
using different towels to the rest of the household.
- Avoid rubbing or touching
eyes and face, (No-one here rubs their eyes after suggestions about
it making KC worse i'm sure!)
- Use a pad and cool boiled water once to remove
discharge from inside of eye outwards. Repeat if needed.
- Don't reuse hankerchiefs (or anyone else's!)
- Wash pillow
cases frequently and don't share linen (so now you are single and all alone!)
- Don't
swim as bacteria can be spread in water (yes, I know all about this
following surgery!)
- Don't share eyedrops or cosmetics and replace any once
cleared of the infection.
- If both eyes are infected, use separate eyedrops for each
eye.
- Discontinue contact lens wear until told you may continue
by your doctor (oops - blind again!)
- Handle and clean contact lenses properly (I'm sure we
are pretty damn good at this by now!)
- You may need to change any contact lenses
and cases to prevent future infections (gee, it gets pretty expensive
wearing lenses sometimes doesn't it!)
Ok... that's it! I'm sure that as
good as we are here being that most of us need to wear lenses, that I didn't
need to tell you how to avoid an infection!
But you know, even being a
nurse i have had enough of these to last me a lifetime! So no matter how
good we all are, sometimes they just sneak up on you and take over! Or
was it leaving lenses in too long, being lazy and not cleaning them properly,
sleeping in them by mistake... LOL, I didn't say that! But the list could
go on and on...
and on!
