Trauma Flashcards
types of ocular trauma
blunt
penetrating
burns - chemical, physical
what is the first thing to do in the case of eye trauma
measure and record baseline visual acuity
why are fluroscein drops useful in eye trauma
can highlight disrupted epithelium
e.g. scratch, abrasion, ulcer, foreign body
what is a hyphaema
blood in anterior chamber forming a fluid level
what is retinal detachment
vitreous humour/gel detaches retina from back wall and peels away retina
what is commotio retina
bruised retina
sign of corneal laceration
misshapen pupil as iris goes to plug wound
what is Seidel’s test used for and how is it done
assess anterior chamber fluid leakage in cornea
use fluroscein dye
if it becomes diluted it is because aqueous humour is leaking through
what imaging should you always do for intra ocular foreign body
Xray
what are the types of chemical burns
acid
alkali
which is more worrying, acid or alkali burn
alkali is more worrying
features of alkali burn
rapid penetration
scarring
penetrates intraocular structures
features of acid burn
less worrying only surface damage coagulates protein cloudy cornea red eye
“china white appearance”
limbal ischaemia
chemical eye injuries should be treated with extreme urgency, true or false
true
irrigation should commence immediately until a neutral pH is achieved after which a detailed history and SLE should be carried out
