“…Our analysis demonstrated that the parameters evaluated did not differ significantly between the eyes from the same dog. Such findings are in agreement with previous studies that show no differences between the right and the left eye from the same animal (Tuft & Coster 1990, Morita 1995, Andrew et al 2001, Pigatto et al 2004). In addition, we observed that the comparison between central and peripheral cornea did not exhibit significant differences in the endothelial cells variables determined.…”

“…The results observed in this study show that normal dog corneal endothelium consisted of a continuous monolayer with mainly hexagonal cells, but also pentagonal and heptagonal variability. This study showed that, despite, minor interspecies differences, the apical morphological characteristics of corneal endothelial cells of dogs were similar to those found in man and rabbit, in that some 65-80% of corneal endothelial cells were hexagonal (Jackson et al 1995, Morita 1995. Other studies on endothelial cells of lower species including bullfrog, trout, gecko and goldfish demonstrated that these species exhibit more variability (Yee et al 1987).…”

“…The specular microscope has been used to quantify endothelial cell size in humans, dogs, rabbits, horses and other animal species (Stapleton & Peiffer 1979, Peiffer et al 1981, Gwin et al 1982, Morita et al 1994, Morita 1995, Abib & Barreto 2001, Andrew et al 2001, 2002, Pigatto et al 2006.…”

Pesq. Vet. Bras. 28(9):427-430, setembro 2008 RESUMO.-[Análise morfológica com microscopia especular do endotélio corneal em olhos de cães.] Foram estudados 20 olhos de 10 cães sem raça definida, machos e fêmeas com 6 anos de idade. A morfologia das células do endotélio da córnea foi analisada utilizando-se microscópio especular de contato. Foram estudadas as regiões central e periférica da córnea. De cada região da córnea foram realizadas três micrografias. De cada micrografia foram analisadas no mínimo 100 células endoteliais. Foram obtidos os valores do polimegatismo e pleomorfismo. O endotélio corneano de cães caracterizou-se por uma monocamada de células poligonais uniformes em tamanho e forma. A forma predominante das células endoteliais foi hexagonal. O índice de polimegatismo foi 0.22. Este estudo demonstrou que a morfologia das células do endotélio da córnea de cães é semelhante à observada em humanos. INTRODUCTIONThe corneal endothelium is a single layer of polygonal cells on the inner surface of the cornea. The endothelial integrity and metabolic activity are essential for continuous maintenance of corneal dehydration and transparency (Waring et al. 1982). Ageing results in a gradual reduction in endothelial cell density and an increase in cell area variability in those species that exhibit minimal mitotic potential (Jackson et al. 1995). Furthermore, morphological changes of endothelium associated with cell loss occur in many conditions including corneal dystrophies, keratoconus, glaucoma, uveitis, blunt ocular trauma, cataract ex-

“…The polymorphism among the studied quadrants was not significantly different, with similar values between 52.23% and 64.54%. The regular pattern of polygonal cells with a predominantly hexagonal shape assessed by optical microscopy was similar to that described in other species (SAILSTAD & PEIFFER, 1981;PEIFFER et al, 1981;MORITA, 1985;PIGATTO et al, 2008;FRANZEN et al, 2010), which corroborates the results in the present study.…”

“…In the current study, there was no significant difference between the right and left eyes. There was no difference in relation to endothelial parameters obtained between fellow eyes of the same individual (MORITA, 1985;ANDREW et al, 2001;PIGATTO et al, 2004;PIGATTO et al, 2005b;PIGATTO et al, 2008;PIGATTO et al, 2009;FRANZEN et al, 2010).…”
