Fig. 3From: 23-gauge transconjunctival vitrectomy in eyes with pre-existing functioning filtering blebsChanges of the subconjunctival fluid after 23-gauge vitrectomy in eyes with functioning filtering blebs. Height of subconjunctival fluid was measured by anterior segment optical coherence tomography (OCT) and compared. The difference in subconjunctival fluid was statistically insignificant (P =0.172).
