Evaluation of blood flow in arteritic anterior ischemic optic neuropathy using laser speckle flowgraphy: A case series.

ABSTRACT:

Background

Arteritic anterior ischemic optic neuropathy (AAION), primarily caused by giant cell arteritis, is a leading cause of blindness. This disease results in significant ocular blood flow (BF) impairment, though data on ocular hemodynamics are limited.

Methods

This observational case series enrolled four patients treated for AAION (age: 81.8 ± 7.8 years; male to female ratio: 3:1) who underwent laser speckle flowgraphy (LSFG) scanning at the initial visit and after steroid treatment in both eyes. Mean blur rate (MBR), an LSFG parameter that represents BF velocity, was obtained in the optic nerve head vessel area (ONH-MV), ONH tissue area (ONH-MT), and peripapillary choroid, in addition to common ophthalmologic parameters.

Results

At the initial visit, all affect
