Variation in Number of Outflow Pathways Off Blebs in Porcine Eyes.
Four separate (superior/inferior/temporal/nasal) 100 microliter subconjunctival blebs were created in each of 11 porcine eyes (n = 44 blebs total), and the number of outflow pathways were counted and compared. A) Each quadrant had a different distribution of total number of pathways seen. B) A statistically significant difference was only seen comparing the temporal to the nasal quadrant. B) The distribution of the number of pathways across all blebs was Zero (18.2%), One (36.4%), Two (38.6%), and Three (6.8%).
