Fluorescein and lissamine green staining patterns on the ocular surface of a patient included in the study: (A) Representative image displaying the fluorescein staining of the corneal surface, showcasing patchy patterns primarily localized in the inferior hemi-cornea, consistent with a Grade 3 severity based on the Oxford Grading Scale (13, 14); (B) image depicting the lissamine green staining on the ocular surface, encompassing the nasal and temporal conjunctiva, as well as the cornea, demonstrating damage indicative of a Grade 3 severity based on the Oxford Grading Scale (13, 14).
