Efeito de drogas utilizadas no tratamento de hipertensão arterial sistêmica sobre a pressão intra-ocular: estudo experimental no cão

Abstract: Objetivo: Estudar os efeitos de duas drogas utilizadas no tratamento de hipertensão arterial sistêmica (captopril e propranolol) sobre a pressão intra-ocular (PIO) e pressão de perfusão (PP) em cães anestesiados. Métodos: Foram estudados 24 cães, divididos em 3 grupos de 8. No primei ro grupo (GI), foi administrado captopril (um inibidor da enzima conversora de angiotensina) na dose de 1,5 mg/kg por via endovenosa. No segundo grupo (GII), foi administrado propranolol (um beta-bloqueador) na dose de 1,5 mg/kg p… Show more

“…It is an invasive procedure where anterior chamber cannulation is performed, and the IOP measurement is obtained using a digital instrument or a mercury column. This approach has been used experimentally in studies related to the occurrence of glaucoma, drug‐induced variations in IOP, and validation of the accuracy of tonometers 7,17–19 . Direct manometry was tested to validate the Mackay‐Marg tonometer in horses, Tono‐Pen tonometer in dogs and horses, 20 and Perkins tonometer in horses and cattle 8 .…”

“…This approach has been used experimentally in studies related to the occurrence of glaucoma, drug-induced variations in IOP, and validation of the accuracy of tonometers. 7,[17][18][19] Direct manometry was tested to validate the Mackay-Marg tonometer in horses, Tono-Pen tonometer in dogs and horses, 20 and Perkins tonometer in horses and cattle. 8 Other factors that can affect IOP measurement in horses include the position of the head, the use of auriculo-palpebral block, sedatives, time of the day, and the type of tonometer.…”

“…Relativo a PIO, em condições fisiológicas, na maioria dos animais varia entre 15mmHg e 25mmHg (GUM; GELLAT, 1997). Algumas condições podem causar variações nestes valores; dentre elas cita-se o ciclo circadiano, idade, processos inflamatórios a nível ocular, medicações e fluxo sanguíneo (ROUSSEAU; BITO, 1981;HASHIMOTO et al, 2002;PICCIONE et al, 2010). Mucha;Camacho (2002) apontaram que na Medicina Veterinária a hipertensão normalmente é secundária a doenças sistêmicas ou à administração de certos medicamentos (ACIERNO; LABATO, 2004), e a hipertensão primária seria uma condição rara.…”
