Waveform changes of laser speckle flowgraphy in the temporal optic nerve head and peripapillary atrophy after trabeculectomy in open-angle glaucoma.

A prospective study was conducted on 33 eyes of 33 patients with open-angle glaucoma who underwent trabeculectomy to investigate hemodynamic changes in the temporal optic nerve head (ONH) and peripapillary atrophy (PPA) after trabeculectomy. Laser speckle flowgraphy of ONH and PPA was performed at baseline and at 1, 3, and 6 months postoperatively. The waveforms of the mean blur rate in the tissue area (MT) in the temporal ONH, βPPA (with Bruch's membrane), and γPPA (without Bruch's membrane) were evaluated.

Relationship Between Changes in the Choroidal Structure and Blood Flow of the Macula After Trabeculectomy.

Purpose: To elucidate the relationship between changes in the choroidal structure and blood flow of the macula after trabeculectomy.

Methods: A prospective study of 30 eyes of 30 patients with glaucoma who underwent trabeculectomy. Enhanced depth imaging optical coherence tomography with choroidal image binarization and laser speckle flowgraphy of the macula were performed at baseline and 1, 3, and 6 months postoperatively.

Effects of Trabeculectomy on Waveform Changes of Laser Speckle Flowgraphy in Open Angle Glaucoma.

Purpose: To investigate the effect of trabeculectomy on the waveform changes of laser speckle flowgraphy (LSFG) in the optic nerve head (ONH) in patients with glaucoma.

Methods: Forty-eight eyes of 48 patients with open angle glaucoma were included in this prospective study. LSFG was performed before and 1, 3, and 6 months after trabeculectomy.

The Relationship Between Interocular Asymmetry of Visual Field Defects and Optic Nerve Head Blood Flow in Patients With Glaucoma.

Purpose: To investigate the association between asymmetry of visual field (VF) defects and optic nerve head (ONH) blood flow in patients with glaucoma using laser speckle flowgraphy.

Methods: In total, 170 eyes of 85 patients with primary open-angle glaucoma were included. Intraocular pressure, VF (Humphrey 24-2, SITA program), mean blur rate in the tissue area (MBR-T) of the ONH measured by laser speckle flowgraphy, axial length, circumpapillary retinal nerve fiber layer thickness (cpRNFLT), disc area, cup/disc area ratio, and parapapillary atrophy (PPA) area was measured in each eye.
