Eye & major trauma

Birmingham (UK generally) is increasingly violent. A careful check will exclude problems. Sometimes the eye is impossible to examine (as lids are shut). Refer/ask on-call eye SPR to assess.

Fist, glass bottle, car windscreen

Visual symptoms: quiz, in pairs, 2 minutes, what are the causes……….

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, central vision

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

Visual symptoms: pattern recognition

Neuro-ophthalmology

• Dilated pupil/ptosis/divergent eye= 3rd n palsy = ?post.com.art.aneurysm

• Vertical diplopia = 4th nerve palsy• One eye convergent = 6th nerve palsy• Dilated pupil/normal sight = adies pupil • Dim vision one eye = optic neuritis

(rarely tumour)• 7th nerve palsy
