Ophtho Flashcards
external hordeolum
- stye = Staph abscess
- Tx: warm compresses. I/D if doesn’t resolve in 48 hrs. Topical Erythro/bacitracin if necessary
presbyopia
-normal loss of lens elasticity/accommodation with age
Spontaneous subconjunctival hemorrhage Tx
- Observation. Benign condition usually
- Measure coag parameters if on anticoag Tx
- Lower BP if elevated
Viral Vs Bacterial vs Allergic conjunctivitis
- Viral: U/L–> B/L. Viral prodrome, watery discharge, follicular injection
- Bacterial: u/l –> B/l. purulent unremitting discharge, non-follicular injection
- Allergic: like viral, except B/L initially and can have conjunctival edema (chemosis). Episodic
Atopic keratoconjunctivits
severe ocular allergy
-Itching, tearing, thick mucus d/c, photophobia, blurred vision. Thickening of eyelids and surrounding skin
Endophthalmitis
Invasive bacterial or fungal infection of the globe due to trauma. May have conjunctival irritation, but will usually have purulent haziness of ocular contents and pus-fluid lever in anterior chamber
-Can be Post OP!! (Cataract surgery)
Viral keratitis
- infection of cornea by HSV or VZV
- corneal vesicles, opacification or dendridic ulcers
Vitreous hemorrhage
sudden loss of vision and onset of floaters.
- Most common cause is DM
- Fundus hard to visualize
Olopatadine, azelastine
mast cell stabilizing agents
-used for Tx of allergic conjunctivitis
HSV keratitis vs plain ol viral conjunctivits
HSV keratitis: painful, red eye with impaired vision, corneal opacification, corneal ulcers
-Use oral antivirals for HSV, expectant for viral conjunctivitis
Amaurosis fugax vs CRAO
- Both can be transient, but amaruosis fugax is by definition
- funduscopy: AF has areas of whitened/edema following arterioles. CRAO has diffuse pallor of optic disc, cherry red fovea, and boxcar segmentation of blood in arteries/veins
