title: The Safety and Efficacy of Two-site Phacotrabeculectomy with Mitomycin C under Retrobulbar and Topical Anesthesia.
abstract: OBJECTIVE
  To evaluate and compare the safety and efficacy of combined two-site phacoemulsification and trabeculectomy surgery with mitomycin C (MMC) in glaucoma-cataract patients with retrobulbar or topical anesthesia.
  
  
  METHODS
  A retrospective, nonrandomized review of consecutive phacotrabeculectomy patients with a minimum follow-up time of 6 months, no previous glaucoma surgeries, and a preoperative visual acuity (VA) greater than light perception. The main outcome measures were preoperative and postoperative VA, intraocular pressure (IOP), use of glaucoma medications, and complications. A complete surgical success required an IOP from 6 to 18 mm Hg, no visually devastating complications, no return to surgery, and no use of glaucoma medications. Qualified success allowed the use of up to two glaucoma medications. Anesthesia groups were compared by student t-tests and log rank comparison of Kaplan-Meier survival rates.
  
  
  RESULTS
  Eighty-seven eyes (83 patients) met inclusion criteria, with a mean follow-up of 19 ± 12 months (6-57 months). The average eye gained 3.1 ± 4.9 lines of VA, lost 4.0 ± 7.1 mm Hg of IOP, and decreased 1.0 ± 1.3 glaucoma medications. Retrobulbar and topical anesthesia groups had statistically equivalent mean changes in VA (p = 0.910), IOP (p = 0.268), and use of glaucoma medications (p = 0.964). Postoperative complication rates were also statistically similar (p = 0.580). Complete success was greater in the retrobulbar group (p = 0.006), however, qualified success was equivalent in both groups (p = 0.769).
  
  
  CONCLUSIONS
  Two-site phacotrabeculectomy with MMC in West Indian patients is as safe and effective for glaucoma-cataract patients with topical anesthesia as it is under retrobulbar anesthesia, and without short-term losses in VA and the chance of serious complications from injection.
