Abstract: To evaluate ocular surface and eyelid modifications occurring in glaucomatous patients diagnosed with glaucoma therapy-related ocular surface disease (GT-OSD) and retinal comorbidities who previously underwent serial Intravitreal injections (IVIs) of aflibercept. Thirty-two eyes of 32 patients with a diagnosis of GT-OSD and concomitant retinal diseases were enrolled in a two-center retrospective observational study. The main outcome measures were: Noninvasive tear film break-up time (NIBUT), Tear meniscus height (TMH), Bulbar redness score (BRS), fluorescein Tear film Break Up Time (TBUT), Corneal Fluorescence Staining (CFS), Schirmer test I (ST), and inferior eyelid Meibomian Glands (MGs) dropout. Differences between treated and fellow eye (TE, FE), were considered. The median number of IVIs (aflibercept) in TE was 4 (interquartile range (IQR) 3-6.50). Mean BRS was significantly lower (p = 0.011) and median TBUT higher (p = 0.037) in TE compared to FE. Despite CFS and NIBUT did not significantly differ between eyes, their median values showed a marginal tendency for better results in TE compared to FE. Serial IVIs of aflibercept positively affected some features of the GT-OSD, reducing conjunctival hyperemia and improving the tear film stability. These preliminary results could open to new strategies for ocular surface management in glaucoma, whether confirmed in larger prospective studies.
