| hyperopia | farsightedness, big round eyeball, rays focus behind the retina |
| hard objects | larger than orbit, transmit force to the eye's surrounding bony regions. can cause swelling and lacerations of the eyebrow |
| elastic objects | small, transmit force to the globe(eyeball) |
| orbital hematoma | "black eye" rupture of superficial blood vessels surrounding the orbit |
| stye | bacterial infection of a sebaceous gland |
| hyphema | blood between anterior chamber between the cornea and pupil. ruptured vessels that supply blood to the iris |
| subconjuctival Hematoma | leakage of blood from superficial blood vessels |
| anisocoria | unequal pupils, either congenital or secondary to brain trauma |
| "tear drop" pupil | sign of corneal laceration or ruptured globe |
| P.E.A.R.L | Pupils Equal And Responsive to Light |
| diplopia | Double vision |
| presbyopia | loss of near vision due to secondary againg |
| eye motility | range of motion of the eye testing |
| weakest point of the orbit | the floor, due to blunt force trauma, will have an inferior displacement of the eye |
| corneal abrasion | definitive diagnosis requires flourecien strips and cobalt blue light |
| Iritis | swelling, involved pupil may be constricted, photo-phobia, sluggish pupillary response to light |
| detached retina | interruption of signal b/w retina and choroid, cause: jarring of head or sneezing. surgical repair. signs/symptoms: flash of lights, curtain vision, halos around objects, blind spots. |
| conjunctivitis: Viral | pink eye, clear discharge, starts off in one eye and then to the next |
| Conjunctivitis: Bacterial | yellowing greenish discharge in one eye only |
