PURPOSE: This pilot study, the first of its type, was conducted to determine the clinical outcome of glaucoma drainage implant (GDI) surgery supplemented with injectable crosslinked hyaluronic acid (HA) in patients with severe glaucoma. METHODS: This was a retrospective chart study involving 10 eyes of 10 patients with severe glaucoma (glaucomatous visual field loss worse than -20 dB) who had previously undergone GDI surgery supplemented with crosslinked HA with a 2-year follow-up. Surgical success was defined as intraocular pressure (IOP) lt;21 mm Hg with a reduction of ≥40% (definition A) or ≥50% (definition B) from baseline IOP on 2 consecutive follow-up visits, IOP gt;5 mm Hg on 2 consecutive follow-up visits, and neither reoperation of glaucoma nor loss of light perception vision. RESULTS: The mean ± SD baseline IOP before GDI was 38.5 ± 10.7 mm Hg, and the mean IOP at the last follow-up visit was 13.0 ± 5.0 mm Hg, with a mean pressure drop of 24.4 ± 10.9 mm Hg (62%; p = 0.005). According to definition A, life-table analysis showed an overall success rate of 80%, while according to definition B, the success rate was 50% after 24 months of follow-up. Complications were infrequent and not serious. No complications resulting from the reticulated HA therapy itself were observed. CONCLUSIONS: In eyes with severe glaucoma, the intraoperative application of crosslinked sodium HA gel may improve the efficacy of GDI surgery.
