  • Title: Perineural infiltrates in Pseudomonas keratitis.
    Author: Robbie SJ, Vega FA, Tint NL, Hau S, Allan B.
    Journal: J Cataract Refract Surg; 2013 Nov; 39(11):1764-7. PubMed ID: 24160385.
    Abstract:
    We describe 2 cases of contact lens-related microbial keratitis caused by infection with Pseudomonas aeruginosa in which perineural infiltrates were observed at presentation. In both cases, examination by confocal microscopy was negative for Acanthamoeba cysts but bacterial cultures and microscopy of corneal scrapings were positive for P aeruginosa. Both cases responded rapidly to treatment with topical levofloxacin with no significant long-term sequelae. These observations indicate that perineural infiltrates may occur in Pseudomonas keratitis without underlying Acanthamoeba infection and are, therefore, not pathognomonic of Acanthamoeba infection.
