If the ulcer is larger than 2 mm, adding fortified antibiotics to fluoroquinolones ensures eradication of all the gram-positive and gram-negative bacteria.
Taper the antibiotics when ulcer improves. If the ulcer worsens or does not improve, consider culturing again, adding fortified antibiotics (e.g., vancomycin and tobramycin), subconjunctival antibiotics. Consider a corneal biopsy if the ulcer does not improve.
Acquaintance on fortified antimicrobial medication, its appropriate usage and timely intervention will help us to treat most of the resistant microbial keratitis and prevent the need for surgical intervention.
For most ulcers (central, large or with robust anterior chamber reaction), start fortified antibiotics. Ensure you have both gram-positive and gram-negative/ Pseudomonas. Our institution typically uses vancomycin 50 mg/mL and ceftazidime 50 mg/mL every hour.
The recent development that has improved the treatment outlook for our patients who present with vision-threatening corneal ulcers is that we are now able to stock a fortified, high-concentration, compounded antibiotic—Fortisite (ImprimisRx, a Harrow company)—in our clinics for the immediate treatment of patients in need.
Dr. Majmudar said the most commonly prescribed antibiotic for corneal ulcers is moxifloxacin, but it has limited gram-negative coverage. He will start a patient on broad-spectrum fortified antibiotics, including fortified cefazolin or vancomycin and fortified tobramycin.
Empirical antibiotic therapy should be promptly started and there are broadly two treatment options available [Table 1]. Commercially available fluoroquinolone monotherapy or a combination therapy of fortified antibiotics (cefazolin 5% and tobramycin or gentamicin 1.4%).
Fortified antibiotics should include a broad spectrum regimen of drops, such as cefazolin 25-50mg/ml and tobramycin or gentamicin 9-14mg/ml every hour while awake. An alternative regimen, including vancomycin 25-50mg/ml and ceftazidime 25-50mg/ml, could be considered, especially for partially treated or unresponsive ulcers.
The traditional therapy for bacterial keratitis is fortified antibiotics, tobramycin (14 mg/mL) 1 drop every hour alternating with fortified cefazolin (50 mg/mL) or vancomycin...
Topical antibiotics remain the best treatment for bacterial keratitis, and a recent review found all commonly prescribed topical antibiotics to be equally effective. However, outcomes remain poor secondary to corneal melting, scarring, and perforation.
