Retrobulbar Hemodynamics and Visual Field Progression in Normal Tension Glaucoma: A Long-Term Follow-Up Study

Table 1

CDI measurements in patients with NTG () of the ophthalmic artery (OA), central retinal artery (CRA), and nasal and temporal posterior ciliary arteries (PCAs). The peak systolic velocities (PSV), end-diastolic velocities (EDV), and resistive indices (RI) are displayed (mean and SD).

	OA	CRA	Nasal PCA	Temporal PCA
PSV	34.9 ± 8.25	7.64 ± 1.69	7.77 ± 1.85	7.79 ± 1.82
EDV	8.6 ± 3.1	2.57 ± 0.67	2.94 ± 0.71	2.9 ± 0.69
RI	0.75 ± 0.06	0.65 ± 0.08	0.62 ± 0.06	0.62 ± 0.06

PSV: peak systolic velocity.
EDV: end-diastolic velocity.
RI: resistive index.
OA: ophthalmic artery.
CRA: central retinal artery.
NPCA: nasal posterior ciliary artery.
TPCA: temporal posterior ciliary artery.
