A comparison of two optical coherence tomography–angiography devices in pseudoexfoliation glaucoma versus primary open-angle glaucoma and healthy subjects

Purpose: To compare peripapillary vascular parameters derived from two optical coherence tomography angiography devices in pseudoexfoliation glaucoma, primary open-angle glaucoma, and healthy controls and to evaluate their diagnostic accuracy. Methods: Observational, cross-sectional study. In total,...

description Purpose: To compare peripapillary vascular parameters derived from two optical coherence tomography angiography devices in pseudoexfoliation glaucoma, primary open-angle glaucoma, and healthy controls and to evaluate their diagnostic accuracy. Methods: Observational, cross-sectional study. In total, 20 eyes with pseudoexfoliation glaucoma, 20 primary open-angle glaucoma eyes matched by peripapillary retinal nerve fiber layer thickness, and 20 control eyes were recruited. Participants underwent standard automated perimetry and peripapillary retinal nerve fiber layer analysis by Optovue and Cirrus optical coherence tomography. Vascular parameters provided by Angiovue and Angioplex optical coherence tomography angiography were compared. Their diagnostic accuracy and correlation with structural and functional parameters were assessed. Results: All peripapillary optical coherence tomography angiography vascular parameters were significantly different among groups (all p

The whole image capillary density and peripapillary capillary density by Angiovue were significantly lower in pseudoexfoliation glaucoma compared with primary open-angle glaucoma (p = 0.009 and p = 0.001, respectively). Conversely, vascular parameters by Angioplex were not statistically different between primary open-angle glaucoma and pseudoexfoliation glaucoma. A good correlation was found using Angiovue between whole image capillary density and visual field mean deviation (0.758, p &lt; 0.001), peripapillary capillary density and visual field mean deviation (0.729, p = 0.001), and peripapillary capillary density and peripapillary retinal nerve fiber layer thickness in eyes with pseudoexfoliation glaucoma (0.716, p = 0.001). Angiovue parameters showed higher area under the receiver operating characteristic curves than Angioplex to discriminate among groups. Conclusion: Only Angiovue detected a significantly lower capillary density in pseudoexfoliation glaucoma compared to primary open-angle glaucoma at similar glaucoma damage. Both, Angiovue and Angioplex demonstrated a decreased capillary density in glaucoma eyes compared to healthy eyes. Furthermore, Angiovue-derived vascular parameters showed better correlation with functional and structural parameters and a higher diagnostic capacity to discriminate among groups compared to Angioplex.</description><identifier>ISSN: 1120-6721</identifier><identifier>EISSN: 1724-6016</identifier><identifier>DOI: 10.1177/1120672118805882</identifier><language>eng</language><publisher>London, England: SAGE Publications</publisher><ispartof>European journal of ophthalmology, 2019-11, Vol.29 (6), p.636-644</ispartof><rights>The Author(s) 2018</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c337t-396bc734b99f38ca23a31907efc7d8f50b6572b45f0c588c1c805360bc6058533</citedby><cites>FETCH-LOGICAL-c337t-396bc734b99f38ca23a31907efc7d8f50b6572b45f0c588c1c805360bc6058533</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,778,782,27907,27908,79115</link.rule.ids></links><search><creatorcontrib>Rebolleda, Gema</creatorcontrib><creatorcontrib>Pérez-Sarriegui, Ane</creatorcontrib><creatorcontrib>De Juan, Victoria</creatorcontrib><creatorcontrib>Ortiz-Toquero, Sara</creatorcontrib><creatorcontrib>Muñoz-Negrete, Francisco J</creatorcontrib><title>A comparison of two optical coherence tomography–angiography devices in pseudoexfoliation glaucoma versus primary open-angle glaucoma and healthy subjects</title><title>European journal of ophthalmology</title><description>Purpose: To compare peripapillary vascular parameters derived from two optical coherence tomography angiography devices in pseudoexfoliation glaucoma, primary open-angle glaucoma, and healthy controls and to evaluate their diagnostic accuracy.
