Hypothesis
This paper will compare the outcomes—safety and efficacy—of three minimally invasive glaucoma surgeries (MIGSs) for intraocular pressure (IOP) reduction in patients with primary open-angle glaucoma (POAG).
Conclusion
The Hydrus, iStent, and GATT are effective alternatives to trabeculectomy for mild to moderate POAG, reducing IOP and medication dependence with manageable safety profiles.
Supporting Evidence
- The Hydrus, iStent, and GATT reduce IOP and medication burden in POAG patients.
- Hydrus showed a 37.09% IOP reduction and a significant decrease in medication use.
- The iStent achieved a 36.39% IOP drop with a notable reduction in medication burden.
- GATT resulted in a 49.33% IOP drop and a significant decrease in medication use.
Takeaway
Doctors are trying new ways to help people with eye pressure problems, and they found that three different surgeries can help lower that pressure and reduce the need for medicine.
Methodology
A literature search of Ovid Medline and Embase identified studies evaluating the Hydrus, iStent, and GATT, analyzing data on IOP reduction, medication use, and complications.
Potential Biases
Potential for selection bias in retrospective studies and variability in patient compliance with prescribed medications.
Limitations
The analysis includes both prospective and retrospective studies, which may introduce selection bias and limit generalizability due to exclusion criteria.
Participant Demographics
The studies included a mix of patients with mild to moderate primary open-angle glaucoma, with some studies specifying gender distribution.
