'''The eye shown in the image has a corneal ulcer.'''
<br />
<FlashCard questions="3">
|q1=Is this ulcer infected or not?
|a1=
Infected. There are
*necrotic edges,
*a cratered base,
*diffuse corneal oedema,
*severe injection and
*severe pain.
|l1=
|q2=What is your most important diagnostic test?
|a2=
A corneal scraping from the necrotic edges of this ulcer should be obtained for Gram staining and for culture. <br><br>
Gram-stained scrapings are the most immediate aid to help differentiate Gram-positive, Gram-negative and fungal organisms, thereby allowing appropriate selection of therapy.
|l2=
|q3=If this ulcer was associated with a bacterial infection, how would you treat it?
|a3=
#Aggressive antibiotic therapy is indicated. Topical antibiotics should be applied frequently, preferably every hour initially.
#This may be most effectively achieved using a subpalpebral lavage catheter.
#After the first 12–24 hours, the rate of medication may be reduced to every 4–6 hours.
#Selection of antibiotics should be based on the results of cytology, and confirmed by culture and sensitivity testing.
#Topical atropine is indicated to relieve discomfort if miosis and ciliary spasm are present.
#The ulcer should be carefully re-evaluated within 24 hours of initiation of treatment, and treatment modified as necessary.
