Optic nerve head perfusion response to reduced blood pressure and increased intraocular pressure

1 June 2015 | | Glaucoma | blood flow, blood pressure, intraocular pressure, optic nerve

The purpose of this prospective study was to test the hypothesis that blood flow autoregulation in the optic nerve head has less reserve to maintain normal blood flow where there is a blood pressure induced decrease in ocular perfusion pressure...

Retinal blood flow changes in glaucoma

1 December 2014 | | Glaucoma | Heidelberg Retina Flowmeter, retinal blood flow, retinal vessel analyser, retinal vessel diameter

This study examined the changes in retinal blood flow and vessel diameter after IOP reduction in high- and low-pressure glaucoma; exfoliation glaucoma (ExG) and normal-tension glaucoma (NTG). Glaucoma progression is seen at times in eyes despite IOP reduction and changes...
