CMN 568 QUESTIONS AND ANSWERS SURE A+
✔✔Herpes Zoster Ophthalmicus - ✔✔- involves ophthalmic division of trigeminal nerve
- more likely to have is VSV rash involves nose and lids
- often inc IOP
✔✔Fungal Keratitis - ✔✔- Gray white corneal infiltrate with feathery edges and
surrounding satellite infiltrates
- usually involving plant material or in agricultural setting
✔✔Ameobic keratitis - ✔✔- d/t acanthambeoba
- risks: freshwater, hot tub, contact wearers
✔✔acute angle closure glaucoma - ✔✔- occurs in older age group
- usually farsighted ppl
- s/s: rapid onset pain, visual loss, halos around light, hard eye ball (inc IOP >50 mm
Hg), eye red, dilated and non-rx pupil, cloudy cornea
- primary - crisis - d/t closure of pre-existing narrow chamber; precipitated by pupillary
dilation
- tx: decrease IOP, may need sx, emergent referral
- if no tx then blind after 2-5 days
✔✔chronic glaucoma - ✔✔- gradual, progressive excavation (cupping) of optic disk
- vision loss starting in periphery (tunnel vision)
- sometimes inc IOP depending on type
- need 2/3 s/s for dx
- tx: meds (prostaglandins, beta blockers), laser or sx, decrease IOP even if normal
✔✔uveitis - ✔✔- inflammation of the uvea causing swelling and irritation
- usually d/t immunologic, systemic disorder
- acute anterior: sudden, blurry vision, trauma, ciliary flush (redness at border of cornea
and sclera)
- posterior: gradual, floaters
- most pedi cases are idiopathic
- tx: corticosteroids and refer urgently
✔✔Cataracts - ✔✔- leading cause of blindness worldwide
- opacities of lens, gradual, progressive blurred vision, glare
- usually BL
- usually age-related
- other causes: congenital (IU unfections), traumatic, 2nd/to sys dz, corticosteroid use,
uveitis, radiation
- need sx if impact ADLs
✔✔retinal detachment - ✔✔- patho: usually d/t retinal tears or holes
- may p/w abnormal or absent red reflex
