“…26,27 When comparing with time domain devices (Visante), the agreement in detected closed angles was moderate to good. 27 Another study with this technology found that Schwalbe's line parameters (SL-AOD and SL-TISA) had a high reproducibility and showed a good correlation with conventional scleral spur parameters (SS-AOD and SS-TISA) and standard gonioscopic grading. 6 When comparing with UBM, OCT performed similarly with quantitative angle measurements in the detection of angle closure.…”

“…We found only five studies evaluating the available spectral domain anterior segment OCT devices. A significant proportion of scleral spurs were not visualized with SD‐OCT imaging resulting in weaker inter‐reader agreements but demonstrated a fair to moderate agreement with gonioscopy . When comparing with time domain devices (Visante), the agreement in detected closed angles was moderate to good .…”

This article aims to review the published literature pertaining to the use of anterior segment optical coherence tomography (AS-OCT) in the evaluation of angle-closure disease. Searches on the available published literature were last conducted on 15 June 2017. Rated as Level I evidence, we found that AS-OCT has shown good sensitivity and moderate diagnostic accuracy to detect narrow angles when compared with gonioscopy. AS-OCT quantitative and qualitative parameters demonstrated strong association with the presence of gonioscopically closed angles. This technology provides an objective non-contact method of assessing the angle that is well tolerated by the patient and correlates well with the information provided by gonioscopy.

“…Regarding developments done in OCT biometers, the new instruments have been shown to be useful to assess corneal and conjunctival thickness in contact lens users [ 5 ], to diagnose closed angles [ 6 ], or to evaluate changes in the ciliary muscle in vivo [ 7 , 8 ]. The Cirrus HD-5000 OCT (Carl Zeiss Meditec, Jena, Germany) is a retinal OCT that can be converted into an anterior segment OCT through an external module.…”

BackgroundTo assess the repeatability and agreement between a new high-resolution optical coherence tomographer (OCT) and a Scheimpflug topographer.Material/MethodsSixty phakic and healthy participants were measured in this study, and one eye per participant was analyzed. Depending on their refractive error, each participant was allocated into a myopic, hyperopic, or emmetropic group. The Cirrus HD-OCT 5000 (Carl Zeiss Meditec, Jena, Germany), and the Sirius Scheimpflug topographer (Costruzione Strumenti Oftalmici, Florence, Italy) were used to take all measurements.ResultsThe repeatability of these instruments to measure the anterior chamber depth, angle-to-angle, thinnest pachymetry, and both nasal and temporal angles was smaller than 0.15 mm, 0.40 mm, 10 μm, and 10 degrees, respectively. However, the repeatability of the Scheimpflug instrument to measure the apex pachymetry was about 15 μm, and for the OCT, it was about 4 μm for all groups. On average, the Sirius Scheimpflug instrument measured shallower anterior chamber depth (about 0.10 mm), shorter angle-to-angle (about 0.5 mm), thinner corneas (approximately 10 μm), and narrower angles (around 5 degrees) for all refractive groups.ConclusionsThe repeatability of the Cirrus OCT and Sirius Scheimpflug instrument was good and independent of the refractive error. Nevertheless, to judge whether these instruments could be used interchangeable, clinical criteria are needed.

“…Devices that image the anterior chamber, such as anterior segment optical coherence tomography (OCT) and Scheimpflug photography, can assist in identifying patients at risk for narrow angle glaucoma, but the precise threshold for treatment with peripheral iridotomy has yet to be widely agreed upon. 44 The standard of care for the evaluation of anatomic narrow angles and angle closure glaucoma remains in-person assessment of the angle by a provider using traditional gonioscopy. Remote operating slitlamp microscopes may play a more important role in the future, as these could allow for improved diagnosis of secondary glaucomas.…”

Background: Glaucoma is the leading cause of irreversible blindness worldwide. Access to glaucoma specialists is challenging and likely to become more difficult as the population ages. Introduction: Using telemedicine for glaucoma (teleglaucoma) has the potential to increase access to glaucoma care by improving efficiency and decreasing the need for long-distance travel for patients. Results: Teleglaucoma programs can be used for screening, diagnostic consultation, and long-term treatment monitoring. Key components of teleglaucoma programs include patient history, equipment, intraocular pressure measurement, pachymetry, anterior chamber imaging/gonioscopy, fundus photography, retinal nerve fiber layer imaging, medical record and imaging software, and skilled personnel. Discussion: Teleglaucoma has tremendous potential to improve patient access to high-quality cost-effective glaucoma care. Conclusions: We have reviewed some special considerations needed to address the complexity of providing guidelineconcordant glaucoma care.
