Abstract
ExPress glaucoma filtration device (GFD) has recently become
available in India as a surgical option for glaucoma patients.
We retrospectively evaluated the outcome of ExPress GFD in 12
eyes with advanced glaucoma with intraocular pressures (IOPs)
not controlled on maximal tolerable medical therapy. The mean
preoperative IOP of 29.58 ± 7.13 mmHg decreased to 17.0 ± 2.67
and 17.40 ± 0.89 mmHg at 6 and 12 months after surgery.
Absolute success (IOP ≤ 18 mmHg, with no additional glaucoma
medications) was achieved in eight cases (66.7%) and qualified
success (IOP ≤ 18 mmHg, with additional glaucoma medications)
in two cases (16.7%) at 1‑year after surgery. Early intervention
was needed in 4 patients; two underwent anterior chamber
reformation while the other two required needling. Two patients required resurgery. There was no significant change in the best
corrected visual acuity postoperatively (P = 0.37). ExPress GFD
does not seem to offer a benefit over standard trabeculectomy in
patients with advanced glaucomatous disease in terms of IOP
control or complication rate. However, due to the small sample
size with a heterogeneous mixture of primary and secondary
glaucoma’s, we await further studies with a larger sample size
and long‑term follow‑up, to see how the device performs.
