Abstract Purpose:Recently, efforts to introduce artificial intelligence(AI) into corneal diagnosis have been advancing. In this study, we focused on “non-infectious corneal infiltrates” in AI automatic classification and examined how peripheral corneal diseases are classified and the influence of bulbar conjunctival hyperemia on this classification.

Subjects and methods:We used 70 anterior segment photographs from 27 patients diagnosed with peripheral corneal ulcers who visited Hiroshima University Hospital during the ten years period up to September 2023 for the development of the corneal AI diagnostic support software(prototype software CorneAI). Additionally, referring to the conjunctival hyperemia grading system from the Allergic Conjunctival Disease Clinical Practice Guidelines(3rd ed), we classified the cases into three ordinal scales:“mild(including no hyperemia),” “moderate,” and “severe,” and compared hyperemia between photographs classified as normal by AI and those classified as abnormal(abnormal group).

Results:Out of the 25 photographs in the acute phase with corneal infiltrates, AI correctly classified 15 photographs(60%) as “non-infectious corneal infiltrates,” while ten misclassifications included two as normal, six as infectious corneal infiltrates, and two as tumors. On the other hand, of the 45 photographs from the remission to quiescent phases, AI correctly classified 23 photographs(51%) as “non-infectious corneal infiltrates” or “scarring,” while misclassifications included 18 as normal, one as deposits, one as a tumor, and two as lens opacity. Among the 70 photographs, the hyperemia classification of the 20 photographs misclassified as normal showed 16 with mild and four with moderate hyperemia, whereas the abnormal group of 50 photographs showed 17 with mild, 24 with moderate, and nine with severe hyperemia, indicating significantly stronger hyperemia in the abnormal group than in the normal group.

Conclusion:Cases may be classified as normal or as different diseases when inflammation is suppressed during the healing process. The degree of hyperemia is believed to influence automatic classification by the CorneAI.
