Uveíte recorrente secundária a leptospirose em equinos: revisão de literatura

Abstract

Characterized by recurrent episodes of inflammation and Immune-mediated response, interrupted by periods of quiescence, Equine Recurrent Uveitis (ERU) is a pathology that usually occurs secondary to infection by Leptospira spp. It mainly affects the uveal tract, which is composed of the iris, ciliary body and choroid, and can be divided into acute, insidious (asymptomatic) and chronic. In the acute phase, clinical signs such as epiphora, hyphema, hypopyon, blepharospasm, hypotonia and miosis are present. The chronic phase encompasses the terminal signs of the disease, such as cataracts, lens dislocation or subluxation, retinal detachment and blindness. The diagnosis is made through a thorough ophthalmic examination, combined with serology to identify the bacteria Leptospira spp. Treatment aims to preserve the integrity of vision, reduce eye discomfort, control inflammation and eliminate bacteria. The prognosis for vision depends on the involvement of the eye's component structures. Sanitary management and vector control are of paramount importance for preventing Leptospirosis infection, and consequently, reducing the occurrence of uveitis.
