The aim of this research was to evaluate the presence of persistent pupillary membrane (PPM) in rats. Thirty rats between three and four months of age and weighing 300-500 grams, provided by the biothery section of the General Administration at Universidade Estadual Paulista (UNESP), Botucatu, SP, Brazil, were subjected to ophthalmological examination by slit lamp biomicroscopy, fluorescein eye stain test and rebound tonometry. We found PPM with possible hereditary origin in 15 animals (50%).
The aim of this research was to measure the intraocular pressure (IOP) of normal chinchilla eyes using the rebound tonometer. A further aim was to assess whether there were differences in the values of intraocular pressure in relation to animals age, gender and time of day. Thirty-six chinchillaswere divided into three groups of 12 chinchillas each, by age: , Group II (20 and 34 months) and Group III (37 and 135 months
RESUMO
Objetivou-se aferir a pressão intraocular (PIO) em olhos saudáveis de chinchilas usando o tonômetro de rebote. Além disso, pretende-se verificar se existem diferenças nos valores de pressão intraocular em relação à idade e ao sexo dos animais e o período do dia. Trinta e seis chinchilas foram divididas em três grupos com 12 animais cada, considerando as idades, designados por GI (2-6 meses), GII (20-34 meses) e GIII (37-135 meses
