Treatment outcomes of paul versus ahmed glaucoma implants
Fig 2
Mean intraocular pressure (IOP, a) and the mean number of IOP-lowering eye drops (b) preoperatively (preop) and at 1 day, 1 week, 6 weeks, and 3, 6, 12, and 18 months after Ahmed® glaucoma implant (AGI) and PAUL® glaucoma implant (PGI).
Compared to preop, IOP was significantly (*) reduced at all follow-ups in both the AGI and PGI group (p < 0.001). At the 18-month follow-up, IOP was significantly lower following PGI than AGI (p = 0.042). Similarly, the number of IOP-lowering eye drops was significantly lower in the PGI compared to the AGI group at the 12- (p = 0.031) and 18-month follow-up (p = 0.018).
