The authors would like to fully acknowledge that in error two incorrect statements were made.
The first incorrect statement is:
A Cochrane review by Jindal et al (2020) assessed non-contact tests for angle closure but did not compare against gonioscopy as a reference standard.
A systematic review and meta-analysis that was published in the Cochrane Library in May 2020 [1], evaluated a range of non-contact tests that including anterior segment optical coherence tomography (AS-OCT) for the detection of an occludable angle. For all 47 studies included in the review (including the 27 AS-OCT studies) the authors compared their accuracy to a gonioscopic reference standard.
The published paper found 23 studies that evaluated AS-OCT to gonioscopy whereas in the Cochrane review by Jindal et al., they investigated 27 studies that evaluated AS-OCT compared to the reference standard of gonioscopy, therefore this that may affect the published paper's findings. Furthermore the published paper has not discussed how their meta-analysis, discussion and conclusions differs from the published Cochrane review by Jindal et al.
In the current review it was reported that 'AS-OCT allows for earlier detection and provides a tool for screening where there is very little else available.' This statement is contrary to the findings of the Cochrane library [1] where the meta-analysis and comparisons of non-contact tests demonstrated that LACD had superior specificity to AS-OCT and similar sensitivity. Furthermore it is generally acknowledged that LACD is a test that can be performed without the need of additional equipment and where a conventional slit-lamp can be used therefore LACD is particularly applicable in settings where costs may be a barrier for implementation.
The second incorrect statement is:
'Our review has been the first to perform a meta-analysis of data that assesses the accuracy of AS-OCT for detecting angle closure against gonioscopy as a reference standard.
The authors would also like to confirm that Jindal et al. published the first systematic review to include a meta analysis of the accuracy of AS-OCT against a gonioscopic reference standard.
