Laser speckle flowgraphy may be useful in identifying eyes with normal-tension glaucoma
Waveform changes in optic nerve head (ONH) blood flow as measured by laser speckle flowgraphy may be useful in differentiating healthy eyes from those with normal-tension glaucoma (NTG), according to the authors of a recent study.
Waveform changes in optic nerve head (ONH) blood flow as measured by laser speckle flowgraphy may be useful in differentiating healthy eyes from those with normal-tension glaucoma (NTG), according to the authors of a recent study published in Investigative Ophthalmology & Visual Science.
For this study, Yukihiro Shiga and fellow researchers at Tohoku University Graduate School of Medicine, Miyagi, Japan, included 61 eyes of 61 patients with NTG, and 21 eyes from age-matched healthy controls. NTG eyes were divided into three groups, based on the progression of visual field defects: mild (mean deviation [MD] > -6.0 dB), moderate (MD -6.0 to -12.0 dB), and severe (MD
Skew was found to be significantly lower in NTG eyes compared with controls (P
