Dynamics of intraocular pressure in patients with refractory glaucoma after transscleral cyclophotocoagulation in micropulse mode

Abstract

A retrospective analysis of IOP values was carried out in 38 patients (38 eyes) with refractory glaucoma stage III–IV after transscleral micropulse cyclophotocoagulation (mCPC) using the Cyclo G6 IRIDEX device on the next day after the procedure, after 1 month, 6, 12 and 24 months after surgery. The dynamics of IOP in the postoperative period largely depends on the initial values of the clinical parameter and does not depend on the patient’s age (p = 0.32), glaucoma stage (p = 0.46), history of antiglaucoma surgery (p = 0.34), the number of used drugs (p = 0.72). After mCPC, patients with lower baseline IOP values have a higher decrease in the indicator (-36 %) and a gradual increase by the follow-up period of 12–24 months compared with patients with high baseline IOP values.
