“…Chan showed the importance of the same device we used for the management of GSs, emphasizing that it could alter treatment decision. Mwanza et al also determined that OCT and stereoscopic photography had disagreement concerning the horizontal and vertical CDR measurements [14]. Both Chan's and Mwanza's studies suggest that the cause of this disagreement could be related to the different disc margin determination, and the assessment of ONH in stereoscopic photography relies on defining the visible disc margin by an expert; on the other hand, the OCT devices they used in their studies, similar to our OCT-A device, recognize BMO, which is accepted as the true anatomical outer border of the neuroretinal rim as the disc margin.…”

“…The patients were divided into three groups according to the DA measurement of NMRC: small (area < 1.6 mm 2 ), medium (area = 1.6-2.0 mm 2 ), and large (area > 2.0 mm 2 ) optic discs. [14] OCT-A ONH scanning OCT-A scans were obtained using an AngioVue OCT-A system (Optovue Inc., Fremont, CA, USA). This device has an A-scan rate of 70,000/s using a light source of 840 nm.…”

“…Absolute ICCs based on the mixed model analysis of variance were used in the present study. An ICC value of <0.4 was accepted to indicate poor agreement, 0.4-0.75 represented fair to good agreement, and a value of >0.75 indicated excellent agreement [14,16]. The ICC calculations were executed before and after the subjects were classified as having small, medium, and large optic discs.…”

Background/objectives To investigate the agreement between optical coherence tomography angiography (OCT-A) and non-mydriatic retinal camera (NMRC) in estimating the optic nerve head (ONH) parameters and evaluate the associations between peripapillary vessel density (VD) with ONH parameters assessed by both devices. Methods The OCT-A and NMRC images of 262 participants (138 eyes were diagnosed with POAG, 63 were glaucoma suspect, and 61 were healthy subjects) were screened retrospectively. The vertical cup-to-disc ratio (VCDR), cup-to-disc area ratio (CDAR), rim area (RA), disc area (DA), and cup volume (CV) were recorded using both devices. Peripapillary VD data were also recorded using OCT-A. The intraclass correlation coefficient (ICC) and Bland-Altman plots were obtained to investigate the agreement between the devices. Age-and intraocular pressure (IOP)-corrected associations between the VD and ONH parameters measured by the two devices were analyzed using linear regression models. Results ICC revealed excellent agreement for VCDR and CDAR, but poor agreement for RA, DA, and CV (ICC = 0.801, 0.793, 0.445, 0.298, and 0.527, respectively). The Bland-Altman plots showed poor agreement for VCDR and CDAR with a large span of limits of agreement (0.500 and 0.528, respectively) and significant proportional biases (P < 0.05). VD was found to be strongly associated with the VCDR and CDAR measurements of both devices (P < 0.001), but the associations were stronger for the measurements of NMRC. ConclusionsThe disagreement between the devices should be considered in clinical practice. The associations between the VD and ONH parameters proved once again the importance of the ONH parameters in terms of the management of glaucoma patients.

Purpose: To assess glaucoma specialists' detection of optic nerve head (ONH) rim tissue that is thin by optical coherence tomography (OCT) criteria. Design: Reliability analysisMethods: 5 clinicians marked the disc margin (DM) and rim margin (RM) on stereo-photos of 151 glaucoma or glaucoma suspect eyes obtained within 3 months of OCT imaging. The photo and OCT infrared image for each eye were colocalized and regionalized into twelve sectors relative to the axis between Bruch's membrane opening (BMO) centroid and the fovea. For each clinician, the distance from BMO centroid to their DM (DM radius) and RM (RM radius) was used to generate sectoral rim width (RW) (DM radius -RM radius) and cup-to-disc ratio (CDR) (RM radius / DM radius) estimates. OCT minimum rim width (MRW) was determined by sector. Among all eyes, for each OCT MRW suspicious sector (< 5% of OCT normative data base), we determined each clinician's detection (clinician CDR ≥ 0.7).Results: Clinicians most commonly failed to detect OCT suspicious rim tissue in the nasal sectors. Among 502 sectors with suspicious OCT MRW all 5 clinicians rated CDR ≥ 0.7 in only 29.5% and all 5 clinicians rated CDR < 0.7 in 21%. OCT suspicious rim thickness was most
