Flashcards in Ocular trauma Deck (9):
Fluorescein drops - function
Orange dye which is taken up by any area of epithelial defect (ulcer, abrasion, foreign body)
When you shine a blue light on the eye, the area of epithelial loss shows up green
Blowout fracture - which orbital wall is usually affected? and what does this result in?
Inferior orbital wall
- fat prolapse through the orbital floor and into the sinus below
Blowout fracture - which extra ocular muscle is most commonly affected? and what eye feature does the patient show?
- loss of upward gaze (even though IR usually depresses the eye, if it is entrapped then the SR can't manage to pull the eye up)
Fluid level of blood in the anterior chamber
This is a significant sign of intraocular injury
Fluid level of white inflammatory cells in the anterior chamber
This occurs due to a build up of fluid under the retina
Chemical burns - which is more aggressive: acid or alkali?
- there is rapid penetration through the ocular surface
