Where does MIGS (minimally invasive glaucoma surgery) fit into the glaucoma management spectrum? At Glaucoma Subspecialty Day on Saturday, Mildred M.G. Olivier, MD, presented results from the American Glaucoma Society–IRIS Registry study of the topic.
Three demographic goals. The study’s goals were to determine the demographic differences in three areas: 1) use of MIGS versus other treatment modalities; 2) effectiveness of MIGS procedures; and 3) adverse outcomes and safety concerns following MIGS. Assessment of the second and third areas is complete, Dr. Olivier said.
Patient characteristics. This retrospective cohort study evaluated patients 40 years of age and older who were considered glaucoma suspects or had been diagnosed with primary open-angle glaucoma (POAG), normal-tension glaucoma, ocular hypertension, pseudoexfoliation glaucoma, or pigment dispersion syndrome.
All told, 383,942 patients (591,116 eyes; 88.69%) underwent cataract surgery alone, while 50,970 patients (75,358 eyes; 11.31%) had combined cataract and MIGS procedures. The surgeries took place between Jan. 1, 2013, and Dec. 31, 2017.
MIGS made inroads. The utilization of MIGS increased from 5.2% to 14.9% during the study period, Dr. Olivier said.
Typical patients? IRIS Registry data showed that those patients who got MIGS tended to be male, black, and over the age of 60. In addition, these “typical” patients had mild to moderate disease, were from the Midwest, and were treated by nonglaucoma specialists. —Jean Shaw

Apply for a Research Grant to Study IRIS Registry Data
Research to Prevent Blindness (RPB) is funding four IRIS Registry research grants this year in a program cosponsored by the Academy. Earlier this year, RPB and the Academy announced four studies that were selected for the second round of IRIS Registry Research awards.
The grants will support use of the database and its analytic capabilities to further population-based research in ophthalmology and blindness prevention. You can find and submit the grant application online. The deadline to apply is Jan. 20, 2020.
