Abstract Details

Purpose:

The aim of the study is to compare the efficacy and safety of combined phacotrabeculectomy with trabeculectomy only, in the treatment of PACG patients with coexisting cataract.

Setting:

Our study was condacted in Clinic for Eye Diseases of the Clinical Centre of Montenegro, Podgorica.

Methods:

This is a comparative case series study, involving 22 patients (22 eyes) with PACG and a coexisting cataract, 11 of these patients were subjected to surgery of phacotrabeculectomy, and 11 only to surgery of trabeculectomy. IOP, filtering blebs, and postoperative complications were compared at the final follow up. Complete success was defined as the one in which IOP was less than 21 mmHg without the use of IOP-lowering medication.

Results:

After 12 months of postoperative follow-up of phacotrabeculectomy and trabeculectomy groups no significant differences were shown in terms of IOP reduction (20.31 ± 6.84) vs. (24.57 ± 13.29) mmHg, P = 0.614), formation rate of functioning blebs (64% (7/11) vs. 91% (10/11), P = 0.094), and complications (45% (5/11) vs. 55% (8/11), P = 0.380). IOP lowering medications were needed for one patient in both groups (9% 1/11). Additional surgery interventions, including anterior chamber reformation and phacoemulsification, were needed in the trabeculectomy group, whereas no surgery was needed postoperatively in the phacotrabeculectomy group.

Conclusions:

Phacotrabeculectomy and trabeculectomy treatments exhibit similar IOP reduction, formation rate of functioning blebs and complications when it comes to the treatment of patients with PACG and co-existent cataract. However, in the group with trabeculectomy only, additional surgical intervention may be necessary for several cases due to cataract and complication after trabeculectomy.
