title: Ex-Press Mini-Implant in the Management of Ocular Hypertension Secondary to Silicone Oil Tamponed.
abstract: This study was designed to compare the success of patients with ocular hypertension, secondary to pars plana vitrectomy and silicone oil tamponade, who received an Ex-PRESS Glaucoma Filtration Device P50 (Alcon Laboratories, Inc. Fort Worth, Texas, USA) to those who had conventional trabeculectomy. The records of 10 eyes of 10 consecutive subjects who had Ex-press implants and 9 eyes of 9 consecutive controls who had trabeculectomy procedures were reviewed. Success was defined as the reduction of intraocular pressure (IOP) in patients who did not require further glaucoma surgery in the eye of note during the entire follow-up. IOP was reduced by 10.3 ± 9.7 mmHg (range -31 to 3) in the Ex-PRESS group and by 13.9 ± 11.4 mmHg (range -35 to -4) in the trabeculectomy group. The difference in the percentage of IOP reduction between the standard trabeculectomy group (42.7%) and the Ex-PRESS group (35.9%) was not statistically significant (P = 0.72). The Ex-PRESS device seems to be at least as effective as the standard trabeculectomy in lowering the IOP of patients with hypertension secondary to pars plana vitrectomy and silicone oil tamponade. Even though the data suggested that the Ex-PRESS device did not result in an overall greater reduction in IOP than trabeculectomy, this does not reach statistical significance.
