Morfologia das células do endotélio de diferentes regiões da córnea de equinos

Abstract

The objective of this study was to evaluate the morphology of different regions of the equine cornea using optical microscopy. Both healthy eyes of eight horses, male or female, of different ages were evaluated. Corneas were stained with alizarin red vital dye and subsequently examined and photographed using optical microscopy. Corneal endothelial morphology of central, superior, inferior, temporal and nasal areas was assessed. One hundred endothelial cells from each corneal area were analyzed. The shape of the corneal endothelial cells of each corneal region was analyzed. Statistical data analysis was conducted using the Student’s t test. Values of P<0.01 were considered significant. Regarding morphological analysis, no statistically significant differences were reported between the equine corneal regions analyzed. The present research suggested that there are no morphological differences between regions of the equine cornea. The values obtained in any region of the equine cornea can be extrapolated to other regions of the cornea and are representative of the cell morphology present in all regions of the cornea.
