Currently, there are no laws that outline the role of tele-optometry in the state of Illinois. This pilot study may assist law makers in determining the usefulness of tele-optometry to underserved communities in urban and rural Illinois. This study aims to evaluate if the spectacle prescription that is determined in a tele-optometric setting is within the interobserver variability standards.
A cohort of 30 optometry students were recruited to participate in the study, excluding those with active ocular disease or recent ocular surgery. A tele-optometric comprehensive eye exam was completed by an in-person technician via DigitalOptometrics™ platform and videoconferencing with an investigator optometrist. This was then followed by the Gold standard in-person comprehensive eye exam by one of our investigator optometrists. Two masked clinicians independently reviewed and compared the exam findings between the tele-optometric exam and the in-person exam to determine if the spectacle prescriptions were valid. Parameters were set to ensure prescriptions were equivalent; spherical component +/- 0.50, cylindrical component +/- 0.50 and axis component +/- 015 degrees. Paired samples t-test and Wilcoxon signed rank test were used for statistical analysis.
No statistically significant difference was found between the spherical, cylindrical, and axis components of the prescriptions found in the tele-optometric exam compared to the in-person exam given p > 0.05. Based on the criteria above, 27/30 (90.0%) of spectacle prescriptions were equivalent between the two exams. Of the 3 prescriptions which were not equivalent, 2 cases were low hyperopes that were given a low myopic prescription in the tele-optometric exam and the third case was a high myope that was slightly given extra minus in the tele-optometric exam.
Our data suggests that spectacle prescriptions were equivalent between tele-optometric and the Gold standard in-person comprehensive eye exams. Careful binocular balance should be employed to ensure patients are not over-minused. With ongoing advances in tele-optometry, these models may provide earlier intervention for corrective lenses in rural and underserved communities.
