This study aimed to detect feline herpesvirus type 1 (FHV-1) in the conjunctival fragments of a cat population by PCR real-time. In addition, we sought to associate these results to ocular signs observed in these animals. For this, we used 70 cats that lived in direct contact, from a residence from Araçatuba, SP. By means of real-time PCR, DNA was detected FHV-1 in 78.1% (25/32) of cats with at least one ocular sign and 26.3% (10/38) of asymptomatic patients, a total prevalence 50% (35/70) in the sample. In animals with signs of conjunctivitis in 60% (21/35) cats were positive at least one of these signals and none of the 40% (14/35) remaining. In cats with signs of keratitis in 49% (17/35) were positive from at least one of the signals and none of the 51% (18/35) remaining. We have detected the presence of FHV-1 at all (17/100%) cats with corneal epithelial defect. There was a significant association between the presence of at least one eye sign, at least a sign of conjunctivitis and keratitis with PCR results. For each ocular sign, only the corneal epithelial defect and blepharospasm were significantly associated with these outcomes and also were associated with each other, suggesting that, in cats with signs of keratitis, corneal epithelial defect may be a factor influencing the emergence of blepharospasm. The high prevalence of ocular infection by FHV-1 found in animals with ocular signs suggested as a possible causative agent of these injuries
