Patient has ocular discharge and itching what are they likely suffering from | allergic conjunctivitis |
What is the tx for allergic conjunctivitis | Cool compresses, Topical antihistamines/decongestants/mast cell stabilizers |
Pt has dendrites that show up on fluorescein staining of the cornea what are they likely suffering from | HSV keratitis |
Why don't you want to miss HSV keratitis | it can progress to corneal scarring and requires prompt tx with antiviral (Viroptic) if outbreak is less than 4 days old could also use acyclovir |
T/F steroids are helpful in tx of HSV keratitis | F NO topical steroids |

Would you send a kid home if they came in with a preseptal cellulitis | no admit them for IV Ab and pediatric consult |
what is the difference between orbital cellulitis and preseptal cellulitis | orbital cellulitis will have involvement of the eye. EOM impairment, pain, fever, proptosis where preseptal cellulitis will not have these findings |
How can you detect a corneal ulcer | use fluorescein dye |
Why do you need to aggressively treat a corneal ulcer | if it is caused by pseudomonas it can destroy a cornea in 6-12 hrs tx with topical fluoroquinolone |
Pt has come in for the third time with an unexplained subconjunctival hemorrhage what may this indicate | may be first indication that their INR is out of whack from anticoagulants |

If a pt has a blunt trauma of the face and a hyphema present what do you need to get | ophthalmology consult. |
If you do a EOM test on a pt with a blunt trauma and they can't look up what might be happening | entrapment of the eye because of a blowout fracture |
T/F the pupil peaks away from the site of penetration or rupture of the globe | F it peaks toward site of penetration or rupture |
What is the first test you should perform on a stable pt with blunt trauma | visual acuity |
If you suspect a ruptured globe what should you do for the pt | get an emergency consult and metal shield check tetanus and get them IV Ab |

What x-ray view is best for visualization of blowout fx | water's view |
Is a blowout fracture an emergency or outpt referral | outpt referral generally |
T/F a chemical injury to the eye is urgent not an emergency | F it is an emergency especially alkali burns because they are generally not painful and can rapidly penetrate the cornea and damage the iris/lens |
What is the tx for chemical splash in the eye | irrigate, irrigate, irrigate check ph and irrigate some more until ph is 7.5-8 then check for particulate matter, corneal clouding, or epithelial defects |
What is a common cause of spontaneous hyphema | sickle cell anemia |
Pt present with a hyphema what do you want to check | elevate pts head and check IOP instill mydriatic to avoid pupillary play |
What education should you give a pt about hyphema before sending them home | that it may rebleed in 3-5 days and if so IOP could increase needing a surgical wash out of anterior chamber |
You perform a slit lamp exam on a pt and notice superficial punctate keratitis what is the likely cause | UV damage to the eye from welding, sun tanning, or Snowblindness |
What is the tx for UV keratitis | cycloplegic, Ab ointment, oral analgesic consider a pressure patch and refer to ophthalmologist |

What is the tx for acute angle closure glaucoma | miotics (pilocarpine), reduce aqueous humor formation with beta blockers (Timoptic), Alpha agonist (loridine), and carbonic anhydrase inhibitors (acetazolamide) and reduce vomiting volume with mannitol |

What conditions can cause papilledema | malignant HTN, pseudotumor cerebri, intracranial tumors, hydrocephalus |
If pt has unilateral papilledema what is the likely cause | Optic nerve edema, papillitis not from elected ICP |
