Despite both CW TSCPC and MP-TSCPC are effective in reducing IOP, with low rates of complications, MP-TSCPC seems to achieve higher success rates with less significant visual acuity loss compared to CW TSCPC.
Purpose:
To compare the efficacy and safety of continuous wave transscleral cyclophotocoagulation (CW TSCPC) using slow-coagulation technique versus micropulse (MP) TSCPC in patients with glaucoma and good visual acuity.
Patient and Methods:
Retrospective multicenter study including patients with logMAR visual acuity (VA) of <0.5 and at least 6 months of follow-up. Surgical success was defined as IOP ≤ 18 mm Hg and at least 30% reduction from baseline IOP with or without glaucoma medication, without loss of >2 lines of vision. For criterion A, patients that required a new CPC session during follow-up were considered as failure. For criterion B, the additional need for CPC was not considered as failure.
Results:
We included a total of 200 eyes from 200 glaucoma patients (110 eyes in CW TSCPC and 90 in MP-TSCPC groups). There was a significant reduction of IOP levels and number of medications after CPC in both groups (
Conclusion:
Both CW TSCPC and MP-TSCPC are safe and effective in reducing IOP, with low rates of complications or serious adverse events.
