In total, 197 children with concomitant strabismus (57 esotropia, 140 exotropia) underwent repeat prism and alternate cover test (PACT) by two orthoptists who were certified by the study, and sensory tests were all performed once. We defined the alignment measurement as stable if the absolute value of the measurement difference between two orthoptists was within 10 prism diopters (PD), and unstable if the difference was 10 PD or greater. We analyzed the relationship between the measurement variability and sensory results, patient age, and angle of deviations.
Results
The mean age of the esotropia and exotropia patients was 68.5 ± 26.3 months (range, 36-164 months) and 96.0 ± 33.7 months (range, 22-200 months), respectively, and there was a significant difference in suppression related variability of alignment, both at distance (P = .004) and at near (P = .046). Anisometropia also showed a significant difference at distance (P = .035) for variability of alignment, and there was no significant statistical effect of age on measurement variability in our study. Variability of alignment is positively associated with the angle of deviation, especially at distance (P = .021 for exotropia, P = .002 for esotropia) with more variability between observers with larger angles of misalignment.
Conclusion
Suppression is an important factor for variability of alignment in childhood concomitant strabismus. Other factors, such as anisometropia and a large angle of strabismus should be taken into account when evaluating binocular alignment.

The American Journal of Ophthalmology is a peer-reviewed, scientific publication that welcomes the submission of original, previously unpublished manuscripts directed to ophthalmologists and visual science specialists describing clinical investigations, clinical observations, and clinically relevant laboratory investigations. Published monthly since 1884, the full text of the American Journal of Ophthalmology and supplementary material are also presented online at www.AJO.com and on ScienceDirect.
The American Journal of Ophthalmology publishes Full-Length Articles, Perspectives, Editorials, Correspondences, Books Reports and Announcements. Brief Reports and Case Reports are no longer published. We recommend submitting Brief Reports and Case Reports to our companion publication, the American Journal of Ophthalmology Case Reports.
Manuscripts are accepted with the understanding that they have not been and will not be published elsewhere substantially in any format, and that there are no ethical problems with the content or data collection. Authors may be requested to produce the data upon which the manuscript is based and to answer expeditiously any questions about the manuscript or its authors.
