Progressive changes in ophthalmic blood velocities in Beagles with primary open angle glaucoma

Abstract: CDI measurements in Beagles with primary open angle glaucoma during the course of 4 years indicate easily measurable and repeatable progressive blood flow abnormalities before the elevation of IOP and, thereafter, with gradually increased levels of IOP.

“…[3][4][5] IOP values in humans are not considered sensitive or specific to make a diagnosis or suggest prognosis, 6 because IOP can be normal in patients affected with normotensive glaucoma (NTG). 7 Unlike in people, increased IOP has historically been a requirement for the diagnosis of clinical glaucoma in dogs, 8 despite pattern-electroretinography (pERG) changes and posterior-segment blood flow abnormalities having been reported before the onset of clinical signs of primary open-angle glaucoma (POAG) in dogs, [9][10][11] suggesting that pathologic changes in the retina can occur before any increase in IOP. Furthermore, glaucoma is a progressive disease in humans and in dogs even with a controlled normalized IOP, suggesting that additional pathophysiologic mechanisms must be involved.…”

“…As inflamações intraoculares, particularmente as uveítes e panuveítes, cursam comumente com edema de córnea, sendo este considerado como sinal clínico clássico de uveíte e, consequentemente, também do glaucoma secundário. No glaucoma crônico, todavia, a tendência é de estiramento do colágeno da córnea e a espessura da córnea tende a diminuir (Gelatt, 2003;Slatter, 2005;Brooks, 2008;Martins et al, 2009). Já em um estudo feito por Mello et al, 2009, comparou- Observou-se que a câmara vítrea é a estrutura intraocular que mais sofre modificações no processo de buftalmia, mudando de magnitude mais significativamente do que qualquer outra câmara ou estrutura ocular durante o glaucoma crônico.…”

“…A câmara vítrea foi a estrutura que mais cresceu na buftalmia, devido a uma possível diferença de constituição das fibras de colágeno da esclera que a circunda. Cabe lembrar que normalmente a esclera da câmara vítrea já é normalmente mais fina do que a esclera que circunda a câmara anterior (Gelatt, 2003;Slatter, 2005).…”
