- always check visual acuity and pupils with penlight
- if suspect bacterial infection, obtain C&S of eye discharge
- flush eye with sterile NS to remove foreign body
- urgent opthalmologic referral & start topical empiric abx tx
- stop contact lens use, do not patch eye
- consider pain script
- consider topical pain meds (ketorolac tromethamine 1 gtt 4 x day)
open angle glaucoma is characterized by
progressive peripheral visual field loss followed by central field loss (late manifestation)
open angle glaucoma classic case
most often in elderly with diabetes; gradual changes in peripheral vision (lost first) then central vision; complains of missions portions of words when reading
open angle glaucoma opthalmoscopic exam reveals
cupping, the optic nerve taking on a hollowed appearance; if cupping, the IOP is too high, refer to opthalmologist

subconjunctival hemorrhage resolves in
1-3 weeks like a bruise, blood reabsorbed
