To report the case of a patient with bilateral herpetic lineal endotheliitis successfully treated with topic steroids and systemic antiviral. 17 year old female with blurred vision, at evaluation localized edema was observed on both corneas associated to Descemet folds and a line of pigmented precipitates. Topic prednisolone and oral acyclovir are initiated with complete resolution of signs and symptoms. Lineal endotheliitis is produced as an answer of endotelial cells to viral infection; maybe due to an immune reaction against some antigens from herpes virus family. It has the potential of relapses even in the absence of viral replication, with secondary untreatable stromal edema. It responds well to antiviral and steroids treatment, although, on those patients who don't improve, is necesary to make additional tests.
