Introduction: Our goal is IOP evaluation after micropulse transscleral cyclophotocoagulation as adjuvant therapy to Ahmed valve implantation.

Methods: This is a descriptive, comparative, retrospective, observational study. The sample was divided into two groups: one group was treated with micropulse transscleral cyclophotocoagulation after Ahmed valve implantation. The other group was only treated with Ahmed valve implantation. The IOP was compared between these two groups at the preoperative visits and on the subsequent 1, 7, 30, 60 and 90 post operative visits.

Results: We registered a 70% IOP reduction (Mean 11 mmHg) on the first postoperative day. During the first week, the reduction was around 72%. Group A had 12 patients (60%) and Group B 8 (40%). When comparing IOP between groups during the 90 days of postoperative follow-up, the mean IOP on Group A was 14.54 mmHg and on Group B was 15.15 mmHg. The results showed no statistical difference (p = 0.7096).

Conclusion: When comparing the Ahmed valve implantation as an only method for IOP regulation with the adjuvant therapy with micropulse transscleral cyclophotocoagulation, the results showed no advantage when using both.
