Abstract
Objective: A number of physiological indicators specific to glaucoma included enlarged optic disc depression and peri-optic disc hemorrhage have been introduced in the examination of fundus test results from comprehensive medical check-ups. Here, we aimed to study the outcomes of diagnosing novel cases of glaucoma and the viability of the indicators after their introduction.
Methods: We compared the outcomes of glaucoma diagnosis before the introduction of the indicators in 2013 with those after their introduction between 2014 and 2017. We retrospectively studied the data from the ledger of medical follow-up administration of those who underwent fundus examinations during comprehensive medical check-ups from 2013 to 2017. Logistic regression analysis adjusted for age and sex was used to assess the association between the introduction of two indicators (enlarged optic disc depression and peri-optic disc hemorrhage) and correct diagnosis of novel cases.
Results: We observed an increase in the number of novel cases of glaucoma after the introduction of the diagnostic indicators. The effectiveness of the glaucoma-specific indicators was 46.5% (enlarged optic disc depression, 29.7%; peri-optic disc hemorrhage, 70.3%), but only 8.5% of the other indicators could successfully diagnose glaucoma. Additionally, there were no significant differences in the rate of correct diagnoses between the indicators (enlarged optic disc depression, 55.3%; peri-optic disc hemorrhage, 57.8%). Significant associations were found between the introduction of two indicators (enlarged optic disc depression and peri-optic disc hemorrhage) and correct diagnosis of novel cases.
Conclusions: The introduction of enlarged optic disc depression and peri-optic disc hemorrhage as specific physiological indicators of glaucoma has contributed to an increase in the number of correct diagnosis of novel cases.
