    Compararam-se os eventos clínicos e as variações da pressão intra-ocular (PIO) das técnicas facoemulsificação endocapsular e extração extracapsular com modificações, no intra e no pós-operatório imediato. A facoemulsificação resultou em menor edema corneano, menor desconforto ocular e menos intercorrências no pós-operatório em relação à extração extracapsular modificada. É imperativo que se faça o monitoramento da PIO no pós-operatório, uma vez que ela ocorreu na facoemulsificação, e o uso de hipotensores oculares, quando os valores da PIO ultrapassarem os limites aceitáveis.The clinical events and variations in intraocular pressure (IOP) that occur in endocapsular phacoemulsification technique were compared to the modified extracapsular extraction technique during the intraoperative and immediate postoperative periods. Phacoemulsification technique caused less corneal edema, less ocular discomfort and fewer postoperative complications than the modified extracapsular extraction technique. The observed increase in postoperative IOP, especially in the case of phacoemulsification, makes pressure monitoring mandatory, as well as the use of ocular hypotensive agents when the IOP exceeds acceptable limits

    Morphological analysis of the corneal endothelium in eyes of dogs using specular microscopy Análise morfológica com microscopia especular do endotélio corneal em olhos de cães

    Both healthy eyes of 10 six-year-old male and female mongrel dogs were studied. With a contact specular microscope the corneal endothelium was examined. Endothelial cells were analyzed in the central and peripheral cornea. Morphological analysis with regard to polymegathism and pleomorphism was performed. Three images of each region with at least 100 cells were obtained. The analysis showed that polygonal cells formed a mosaic-like pattern uniform in size and shape. The predominant number of cells was hexagonal. The polymegathism index was 0.22. The study demonstrates that the morphology of the normal corneal endothelial cells of dogs is similar to that found in the human cornea.<br>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

    Feline intraocular sarcoma associated with phthisis bulbi

    Two cases of feline intraocular sarcoma were reported in stray cats that presented blindness and hypotonia of the affected eye for years before the tumor development. Phthisis bulbi, a final stage of a severe inflammation of the eye, is frequently unmonitored because eyes are blind, small, opaque, and not painful. Yet, this report shows that monitoring and early enucleation of eyes of cats with phthisis bulbi are important and should be considered as a treatment option, because feline intraocular sarcoma is an aggressive tumor that significantly decreases live expectancy
