One Case of Direct Evidence’s peripheral ulcerative keratitis with Tuberculosis

Abstract

Abstract Compared with intraocular tuberculosis (TB), ocular tuberculosis (OTB) with ocular surface involvement is rare. Corneal involvement in OTB can be characterized by interstitial keratitis or peripheral ulcer-ative keratitis(PUK). We report a case of PUK with direct basis as the sign of tuberculosis. The corneal ulcer scraping was performed and mycobacterium TB DNA polymerase chain reaction(PCR) was positive.After a month of oral anti tuberculosis treatment, the corneal ulcer was completely controlled.
