dacrocystitis , hordeolum , dental
infection)
 Complication of trauma ( skin trauma with
inoculation )
 Hematogenous ( if immunocompromised )
Age :

Central Retinal
Artery Occlusion
Etiology :
Occlusion of blood flow by :
1. Emboli from carotid artery or heart ( AF .
Endocarditis , valvular disease )
2. Thrombus
3. Temporal arteritis
Result in acute painless loss of vision due to
oxygen starvation of the retinal tissues and
eventual cell death .
Clinical features :

> 90 min of complete CRAO )
 Massage the globe to dislodge embolus ( compress eye with heel of
hand for 10 seconds , release for 10 seconds , repeat for 5 min )
 Decrease IOP
- topical BB, IV acetazolamide , IV mannitol
- or drain aqueous fluid by anterior chamber paracentesis ( carries risk of
infection , lens puncture .

deviated slightly temporally and inferiorly and he has
difficulty adducting and elevating the eye .
What is the most likely diagnosis ?
A)grave’s disease
B)Horner syndrome
C)3rd nerve palsy
D)Myasthenia gravis
Third Nerve Palsy
What are the nerves that are
responsible for eye movement ??
CN 3 : occulomotor
nerve
CN 4 : Trochlear nerve
CN 6 : abducent nerve
Extra ocular muscles
Remember LR6 SO4
Occulomotor Nerve also supply levator
palpebrae superioris. ( elevate eye lid )
and
have connection with neurons in ciliary
ganglion which innervate the pupillary
sphincter ( control constriction of the pupil )
What you see in
rd
3 nerve palsy ?
 Ptosis
 dilated pupil
 an eye that is down
and out.
 diplopia with or
without pain
Etiology
Aneurysm ( posterior communicating
artery aneurysm )
Intraocular tumor
Ischemia ( DM )
Trauma
Work up :
Complete ocular examination
CNS imaging to R/O aneurysm or
mass
ESR and CRP to R/O GCA
Treatment :
Treat the underlying causes if present .
Patch or prism over affected eye if there is
symptomatic diplopia ( but not for < 11 years old
for the risk of amblyopia )
What is the most likely diagnosis?
A) anterior uveitis
B) Optic neuritis
C) Acute Angle glaucoma
D) Giant cell arteritis
Glaucoma
Definition :
Two main types :
Optic nerve Damage due
to increase IOP.
1. Open angle glaucoma.
2. Closed angle glaucoma .
Normal aqueous pathway
 Aqueous is made by the ciliary body and secreted into posterior
chamber .
 Aqueous passes through the pupil into the anterior chamber .
 Most of the aqueous leaves the eye via the trabecular
meshwork -> schlemm’s canal -> bloodstream .
 Small portion ( 4%) drains via uveoscleral pathway .
acute angle closure glaucoma
 Pathogenesis = pupil block
mechanism
In response to pupil dilatation (e.g. dark
condition ) -> peripheral iris bunches up
-> increase resistant to aqueous flow .
Build up of aqueous in posterior chamber
-> bows iris forward -> closes drainage
angle .
Risk factors :
 Female
 Family history
 Small eye ( long sighted , hypermetropic )
 Asian ethnicity .
 Age >70 years old
 Mature cataract
 Shallow anterior chamber
 Pupil dilation ( topical and systemic anticholinergic ,
stress , darkness )
Acute angle glaucoma is
about 5% of all glaucoma
cases .
Clinical features :
 IOP > 40 mmHg ( by tonometry )
 Cloudy, injected cornea ( seen by slit lamp ) .
 Fixed , oval , mid - dilated pupil ( seen by slit lamp )
 Halos around the light.
 Red painful unilateral eye .
 Reduced vision .
 Watering .
 Nausea, vomiting , abdominal pain .
Halos around light
Complication :
 irreversible loss of vision within
hours to days if untreated .
Permanent peripheral anterior
synechia result in permanent
angle closure .
Ocular emergency :
aqueous suppressants and hyperosmotic
agents :

-
Decrease aqueous humor formation :
Topical BB ( timolol )
Topical alfa adrenergic agonist ( brimonidine )
Topical carbonic anhydrase inhibitor (dorzolamide )
Systemic carbonic anhydrase inhibitor ( acetazolamide IV or oral )

-
Increase aqueous outflow :
topical prostaglandin analog ( latanoprost ) .
Topical carbonic anhydrase inhibitor
Topical cholinergic ( pilocarpine : mitotic drops to reserve pupillary block )
 Hyperosmotic agent : mannitol ( rarely used now , mostly OR cases ) , or oral
glycerin .
Definitive treatment :
Laser peripheral iridotomy
(bilaterally)
What is the diagnosis you would
most worry about ??
A) Cataract
B) Endophthalmitis
C) GCA
D) Retinal detachment
E) Vitreous detachment
Retinal Detachment
Definition
The potential space
between the
neuroretina and the
retinal pigment
epithelium (loosely
attached in the eye )
become separated .
Risk factors :

 Retinal detachment in other
eye
 High myope ( short sighted ,
large eye ).
Clinical features :

mmHg lower than the
other eye
 Most common
presentation is unilateral
blurry vision without pain
or redness (PAINLESS
acute loss of vision )
Treatment
 Prophylactic : symptomatic tear ( flash or floaters ) can be sealed off with laser /
cryotherapy .
 Therapeutic :
 Rhegmatogenous :
-
Scleral buckle procedure
-
Pneumatic retinopathy
-
Vitrectomy plus injection of gas ( silicone oil in recurrent detachment )
 Tractional :
Vitrectomy +/- membrane removal / scleral buckling/ injection of intraocular gas
or silicone oil as necessary
 Exudative : nonsurgical , any underlying disease should be treated if possible .

Ischemic optic
neuropathy
It is the most common cause of
optic nerve pathology causing
visual loss in patients older than
50 years .
Caused by blockage of optic nerve blood
supply
Blockage can be due to :
• Inflammation of the arteries as a part of Giant cell
arteritis = Arteritic Type
or
• Without inflammation of arteries = non arteritic type
( most cases are idiopathic ) .
Blood supply to the optic nerve
Anterior part : optic nerve head , which is
supplied primarily by the posterior ciliary
circulation .
Posterior part : supplied by multiple
sources other than posterior ciliary
circulation .
Classification of ION :
1 - Anterior ION : involve 1mm segment of the optic
disc so it will cause disc swelling or edema
2 – Posterior ION : involve any portion of optic nerve
posterior to the optic disc so will not cause disc
edema .
Anterior ION :
Arteritic
Non arteritic
Posterior ION
Arteritic
Non arteritic
Surgical : as a
complication from
a surgical
complication .
Non Arteritic is more common than Arteritic type
 Arteritic ION is much more emergent than Non
Arteritic .
Anterior ION is more common than Posterior
ION.
PION is very rare and is generally a diagnosis of
exclusion.

80-100 mg PO daily .
 Note that without steroid , other eye can become involved within 1
to 7 days .
 Treatment should last at least 6 to 12 months with smallest steroid
dose that suppresses the disease .
