Summary
Retinal oximetry measurements using SRO are highly reproducible in both treated glaucomatous and normal eyes.
Abstract
AIM
To measure the reproducibility of retinal oxygen saturation (SaO2) levels among treated glaucomatous eyes and normal controls in a prospective non-randomised study.
METHODS
Patients with perimetric glaucoma (PG) and normal controls were included. Exclusion criteria for both groups included visual acuity 0.05). In the PG group, the a.SaO2 had a CoV of 1.6%, a CoR of 4.7 and an ICC of 0.97; the v.SaO2 had a CoV of 5.9%, a CoR of 8.7 and an ICC of 0.96. In normals, the a.SaO2 had a CoV of 0.98%, a CoR of 3.3 and an ICC of 0.97; the v.SaO2 had a CoV of 4.8%, a CoR of 7.7 and an ICC of 0.93.
CONCLUSIONS
Retinal oximetry measurements using SRO are highly reproducible in both treated glaucomatous and normal eyes.
