At follow-up 2.5 months after initial presentation, her conjunctivitis
had resolved and corneal thinning had been
stable at 70–80 % thinning, but iris vessels of the left eye
remained significantly dilated. She was started on Tobradex
ophthalmic ointment twice daily (given that her prior
MRSA cultures were gentamicin sensitive and to reduce
the inflammation likely driving her persistently dilated left
eye iris vessels) and continued her oral doxycycline 100 mg
twice daily. Four months after initial presentation, her left
cornea had a central 2.0-mm area of 80 % corneal thinning
and scarring but with no infiltrate or epithelial defect and a
left eye visual acuity at 20/400.
