Purpose: To investigate the clinical courses between phacoemulsification (PE) and PE with combined trabeculectomy(phacotrabeculectomy, PETL) in closed-angle patients with re-elevated intraocular pressure (IOP) after laser peripheral iridotomy(LPI).
Methods: Closed-angle patients whose IOP re-elevated between 19 and 38 mm Hg after LPI were included. Medical records of 26 patients in the PE group and 21 patients in the PETL group who were followed for more than 12 months after surgery were reviewed for clinical course.
Results: The IOP courses after surgery showed no statistical difference during the study period except at 1 and 7 days after surgery, in which IOP in the PETL group were lower than that in the PE group. The number of anti-glaucoma drugs also showed no significant difference except at 6 months, when the number was greater in the PE group. Success rates for IOP below 18 mm Hg at 3 years were 96.2% in the PE group, higher than the 69.8% in the PETL group (Log Rank test, p = 0.015). Postoperative complications were found in 2 patients in the PE group and in 8 patients in the PETL group (Fisher’s exact test, p = 0.028).
Conclusions: We suggest that PE is a viable surgical alternative to PETL in closed-angle patients who have mildly re-elevated IOP after LPI.
