Eye Injuries

1-Blunt(contusion)

2-Perforating Injury

3-Perforating

Injury & retained

foreign body

4-Chemicals ( acid – alkaline ) & burns

5-Sonar (

sun

rayes

U

ltra violet

Enfera

red)

6-Extraocular foreign body

Blunt Trauma

By fist ball can cause abrasion to rupture globe

1-

cornea

( abrasion –

oedema

– staining – tear )

2-

sclera

(rupture –

haemorrhage

)

3-

iris &

ciliary

body

(

miosis

–

mydriasis

– laceration –

iridodialysis

–

antiflexion

–

retroflexion

–

aniridia

–

cyclodialysis

–

hyphaema

)

4-

lens

(

vossius’s

ring – cataract – dislocation – subluxation – tear )

5-

vitreous

( opacities –

haemorrhage

– herniation – loss )

6-

choroid

(rupture –

haemorrhage

– detachment )

7-

retina

( macular edema – degeneration – cyst hole – retinal tear – retinopathy )

8-

optic nerve

( atrophy – avulsion )

Orbital and

subconjunctival

haemorrage

Corneal foreign body

Corneal abrasion

staind

with

furecein

Hyphaema

Iridodialysis

Subluxated

Metal foreign body embedded the iris

Perforating wound with prolapsed iris inferiorly

Perforating Injury

Aim of treatment :

i

. To save vision

ii. To prevent sympathetic

ophthalmitis

Signs :

1

. drop of VA

2

.

Hypotony

3

. Shallow AC –

hage

4. change of pupil

5.

conj

edema (

chemosis

)

6.

subconj

hage

7. iris hole

8. wound track in corneal , lens & vitreous

Perforating

Injury with retained foreign body

( iron – steel – stone – glass – lead pellet – wood spicules )

Effects :

1. mechanical

2. infection

3. chemical action ( inert metal – little reaction – suppuration )

4. degenerative changes (

siderosis

-

chalcosis

)

Choroidal

tears and

haemorrhage

Solar macular burn
