If time, work out how you would refer, treat
3. Feedback…………what conditions to expect

Will be many conditions you’re
unsure of. Exclude more urgent
problems; ring for advice.
17. Check discs & retina
• Dim light
• pupils, eyelids, red reflex
• Patients look in distance, 15o
up
• Try not to obstruct sight in other eye,
otherwise examined eye will move.
• Look 15o
medially, to see the optic nerve
first.
• Going close increases field of view
• Optic nerve first
• Move along vessels
• Find macula last (this will make pupils
small)
• Dilating pupil makes examination easier,
quicker and more complete. But it is
time consuming, and is rarely needed to
exclude papilloedema .
22. Slides, with a few questions
Lids
Conjunctivitis
Foreign body & cornea
Anterior segment (uveitis/glaucoma)
Retina

Foreign body Diagnose how…………

iritis findings……………………….

Acute glaucoma findings……………………….
Refer? …comments……………
Chemical burn Treat…………………………….
Which is worst chemical…………..
24. Lids
A chalazion
some ‘point’ with pus needing draining:
some lid infections need systemic antibiotics
Severe infections
like this orbital
cellulitis need
admission (often
under
paediatricians) and
IV antibiotics
28. Foreign body & fluorescein drops
•Fluorescein drops do not sting and are
comfortable for children (all other drops
sting).
•Arc eye: wake up with pain at night, due
to an ultraviolet (welding) flash earlier in
the day.
29. Conjunctiva & anterior chamber
Conjunctivitis
No pain
Watery eye
Gritty, something
in eye
Iritis/acute glaucoma
Achy eye
Tender
% fixed/sluggish pupil
Glaucoma..eye hard
32. Treatment foreign body/conjunctivitis
Remove foreign body
Fluorescein excludes corneal ulcers
Chloramphenical drops qid (ointment tid), mild cases
Severer cases 2 hourly drops
Conjunctivitis is very infectious
Refer severe cases
33. Examples of nastier corneal problems
•Dendritic ulcer (acyclovir x5
day x 10d)
•Corneal abscess
•Giant papillary conjunctivitis
•pterygium
34. Pain & irritation
Ache Inflammation
(acute glaucoma, iritis,
episcleritis etc)
Gritty scratchy eye, as
though there is something
there
Foreign body/
abrasion/ulcer
(=uneven surface)
Watery red eye
No pain
conjunctivitis
Severe knife like pain trigeminal neuralgia,
spasms: history important
39. Acute glaucoma
• Achy eye, misty
vision
• Previous mild
episodes with haloes
• Pupil fixed
(sluggish), semi-
dilated
• Eye feels hard
Press eye with 2
fingers..Try this on your
own eye
40. n o r m a l s h a llo w
a n t e r io r
c h a m b e r
Acute glaucoma cont
46. Sudden, most of sight, or part
TIA: retinal emboli, central/branch retinal artery
occlusion
47. retinal artery occlusion
If within 3 hours of onset, can dislodge clot
(massage, IV diamox, AC paracentesis)
Refer ASAP, aspirin
ESR (10% are GCA)
48. Loss of sight over weeks/days/hours
• Retinal detachment, with
flashes/floaters
• Ischaemic optic neuropathy
(older patients)
(%GCA with GCA symptoms)
• With pain on movement: optic
neuritis (younger patients)
• Retinal vein occlusion
• Eye conditions: may lose
top/bottom half of sight
49. Retinal detachment
1. Vitreous gel liquifies (floaters)
2. May pull retina if attached (flashes)
3. Causes a hole
4. Fluid enters hole
5. Retina peels off
(more floaters, vision affected)
6. Dilate pupil, with careful look usually
obvious, refer same day
50. Loss of sight over months
• Cataract
• Many other problems,
dilate pupil…………
• red reflex
• Retina
• discs
51. Visual symptoms: quiz, in pairs, 2 minutes, what are the causes……….
Misty vision Aches…………
No ache…………………
Sudden onset visual loss ………………….
Specific symptoms Give examples……………………….
Loss of sight on one side What may be going on?………….
…………………………………….
Episodes of visual loss ………………………………….
Clues…………………………..
Blurred vision with flashes
and floaters
……………………………….
52. Visual symptoms
Misty
vision
If eye aches, acute glaucoma/uveitis
No ache, cataract/retinal disease etc
Sudden
onset
visual loss
Vascular
Specific
symptoms
E.g. GCA, optic neuritis, HZO
Loss of sight on one side Differentiate eg right side of
BOTH eyes (CVA), or ONE
eye alone (eye disease)
Episodes of visual
loss
TIAs: occur suddenly, resolves
over minutes
Blurred vision with
flashes and floaters
retinal detachment/vitreous
haemorrhage
53. Eye general health: 1
• What is the history?
– Vomiting
– Nausea
– Stomach not tender
– Headache?
– Sight GOOD
– Papilloedema
– Refer to RMO/neurosurgeon
healthy
54. • Loss of sight 2 days ago, one eye
• Headaches 1 week
• Shoulder pains months
• Weight loss months
• Jaw aches eating
• unwell months
• Test needed:
• ESR high
• Giant cell arteritis
• (if eye OK, refer to RMO)
Eye general health: 2
55. • Episcleritis
• Scleritis
• No steroid drops from casualty
• Herpes zoster:
– IV antiviral if immunosuppressed
Eye general health: 3
56. Eye & major trauma
Birmingham and Tamworth are increasingly violent.
A careful eye exam will exclude problems.
Sometimes the eye is impossible to examine (as
lids are shut). Refer/ask on-call eye SPR to assess.
Causes: fist, glass bottle, car windscreen.
57. Eye & major trauma: perforating
glass bottle, car windscreen, dart
Tetanus, antibiotic, refer (ring
first), starve for operating
theatre
58. Eye & major trauma: blunt
Fist, foot, squash ball: blunt eye injury, refer many
Hyphaema:
% retinal
detachment also
59. Eye & major trauma: blunt cont.
Fist, foot, squash ball: orbit injury
Double vision:
Globe itself fine, but floor of orbit fractured, and inferior
rectus muscle tethered = blow out fracture
60. Eye & previous eye surgery
There are many possible problems after ocular
surgery: refer, sometimes urgently
62. • Common conditions less serious, need to treat (includes antibiotics,
chloramphenicol)
• Serious conditions: history provides a clue, but a careful examination through a
dilated pupil and ophthalmoscope excludes most major pathology
• Generally provide an escape plan “see your doctor if it does not get better” etc
• Serious conditions always need expert advice
• Only really ‘immediate’ action is for chemical burn such as plaster under the
lids…irrigate profusely.
• ASAP retinal artery occlusion, GCA
• Within hours..acute glaucoma
• Retinal detachment same day, operation next day often
• Many ‘none’ urgent conditions present; local optometrists help with less urgent
• RMO or nursing colleague can provide useful advice, as can on-call time in
Eye Casualty

Top: A Subtarsal foreign body. Need to evert lid..use a cotton bud. Fluorescein drops show up any scratch/abrasion. Easier to see with a blue light, but an ordinary light is sufficient. Should the foreign body be removed? Yes no What is the treatment? ………………………………………………………………………………………. Does this need referral? Yes no Bottom A corneal foreign body.
A corneal foreign body. With local anaesthetic drops first (benoxinate or amethocaine or lignocaine), use a sterile green needle (holding it flat against the cornea) to remove the foreign body. You cannot do this if you are tired! Sometimes a blunt piece of sterile plastic may be safer. There may be a rust ring left, but this heals (an ophthalmologist can remove a dense rust ring.)
