causes in children.

- gonorrhea: single dose ceftriaxone
- herpes: refer to opthalmologist
Corneal abrasion: definition, cause, findings, treatment
- disruption of cornea (clear covering of eye)

pressure.Acute closed: eye pain and visual disturbance with N/V.
- Acute: Emergency. immediate medication and surgery. Chronic: consult
opthalmologist and monitor. Bimatropost, and beta-blockers. Laser-therapy
