Abstract Details

Purpose:

To investigate efficacy of bleb revision depending on the model of the shunt.

Setting:

'The New Vision' Clinic group, Kyiv, Cherkasy, Khmelnitsky, Ukraine

Methods:

60 patients with open-angle glaucoma with previous Ex-PRESS shunt surgery and cataract phacoemulsification were divided into 2 groups of 30 persons (30 eyes) each, depending on the model of the implanted device (P-50, P-200).Visual acuity, IOP, number of medications and complications were assessed in 3, 6, 9, 12. 18, 24 and 30 months. Patients with IOP over 21mm Hg on 3 or more medications underwent subsequent bleb revision with mitomycin C, restoration of the shunt passability with viscocanalostomy cannula and suprachoroidal space drainage. Follow-up time after the revision was 21 months.

Results:

In group І during the follow-up period IOP elevated over 21mm Hg in 11 eyes, in group II – in 7 eyes. In both groups medications reduced IOP in 6 eyes. In 5 eyes in group І and in 1 eye in group ІІ, where IOP was over 21mm Hg on 3 or more medications, bleb revision was performed. In group I it was successful in 4 eyes, in 1 patient revision was repeated in 6 months. In group II only 1 patient underwent bleb revision after Ex-PRESS shunt surgery. It was successful throughout the follow-up period.

Conclusions:

Patients with P-200 model of glaucoma EX–PRESS filtration device showed better IOP control, less need of post-operative medications and subsequent bleb revision. Further research with larger sample size and longer follow-up is needed to confirm these results.
