Primary entropion in persian cats Ciência Rural
Laus,José Luiz; Vicenti,Felipe Antônio Mendes; Talieri,Ivia Carmen; Jorge,Adriana Torrecilhas; Bolzan,Aline Adriana.
Entropion is defined as the inward rolling of the eyelid margin in which the eyelashes and eyelid hair (frequently the lower lateral lid) rub the cornea. Etiologies may be congenital, spastic, or cicatricial. This condition usually causes epiphora, blepharospasm, photophobia, conjunctivitis, purulent discharge, corneal vascularization, pigmentation and ulceration, if not surgically treated. Congenital entropion commonly affects dogs and is frequently hereditary in some breeds, whereas cats are uncommonly affected. A predilection for the Persian breed to present primary entropion has been suggested. The authors report two cases of entropion in Persian cats referred to the Ophthalmology Section of Veterinary College of São Paulo State University - UNESP,...

Qualitative and quantitative tear film abnormalities in dogs Ciência Rural
Ribeiro,Alexandre Pinto; Brito,Fabio Luiz da Cunha; Martins,Bianca da Costa; Mamede,Fabrício; Laus,José Luiz.
Tear film disorders in dogs can be classified into quantitative or qualitative abnormalities, or both, and are commonly observed in daily clinical practice. Inadequate production of one or more tear film components can lead to variable degrees of ocular disorders, called keratoconjunctivitis sicca. Keratoconjunctivitis sicca in dogs has several causes, but in most cases the disease is idiopathic, with T lymphocytes playing a role. In veterinary medicine, the diagnosis is made based on the results of the Schirmer tear test. In this article, we review aspects related to the etiopathogenesis and diagnosis of keratoconjunctivitis sicca in dogs and discuss new therapeutic modalities for this disease.

Honsho,Cristiane dos Santos; Oriá,Arianne Pontes; Lazaro Júnior,Luiz Paulo da Veiga Monteiro; Dorea Neto,Francisco; Laus,José Luiz.
Electroretinography is the technique that allows the evaluation of changes in electrical potential that occur when the eye is stimulated by light. Such changes reflect the response of several retinal cells including photoreceptors (cones and rods). Thus it evaluates the retinal functionality and can diagnose abnormalities in retinas seem to be normal by ophthalmoscopy. Due to the constant evolution in veterinary ophthalmology, new centers of retinal electrophysiology have been introduced around the world either for early diagnosis of retinopathies or for preoperative evaluation of animals with cataracts and glaucoma, as well as for continuing research.
