Real-world evidence of the use of Cloudscaper optotypes versus LEA symbols for virtual or digital visual acuity measurement in children aged 3 to 16 years
Cloudscaper symbols provide a reliable tool for visual screening in children. Although they slightly underestimate visual acuity compared to LEA symbols - a finding also reported when comparing ETDRS letters with LEA symbols - Cloudscaper symbols show strong agreement with Snellen E chart measurements. This suggests that Cloudscaper symbols allow precise visual acuity assessment comparable to the gold standard.
