Ophthalmologic findings, including visual acuity, intraocular pressure, CDR measured by clinical assessment, average retinal nerve fiber layer thickness, and average CDR measured by OCT, were recorded for each participant\u2019s initial and final examinations.

At initial presentation, 53 eyes had CDRs recorded by both clinical assessment and OCT, and at final presentation, 93 eyes had CDRs measured by both modalities.

However, the average difference between CDR measured clinically and by OCT was &amp;lt;0.1. Thus, OCT may be a suitable way to measure CDR in pediatric glaucoma suspects, especially when clinical exam proves difficult. Further research is needed to assess CDR in glaucoma suspects using OCT longitudinally and in the context of other optic disc measurements, such as disc area.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fopht.2024.1479286","type":"journal-article","created":{"date-parts":[[2024,12,3]],"date-time":"2024-12-03T05:10:10Z","timestamp":1733202610000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Cup-to-disc
