Reevaluating Plate Dimensions in Glaucoma Drainage Devices: The Case for Smaller Sizes

Share

1

The optimal size for glaucoma drainage devices (GDDs) may be smaller than the traditionally favored 350 mm² plate.
2

Comparative studies show no significant differences in outcomes between 250 mm² and 350 mm² Baerveldt devices.
3

Long-term data indicate that increasing plate size beyond a certain point may not improve outcomes and could lead to adverse effects.
4

The PAUL Glaucoma Implant (PGI) features a narrower tube lumen and shows comparable efficacy to Baerveldt while minimizing hypotony risk.

Future GDD designs may focus on smaller plates and innovative materials rather than solely increasing surface area for better outcomes.
