Progressing at Low Pressures: A Case for the OPAP

John P. Berdahl, MD; Natalia Morales, MD; Tanner J. Ferguson, MD; and Justin Schweitzer, OD, FAAO

Show Description +

John P. Berdahl, MD; Natalia Morales, MD; and Justin Schweitzer, OD, FAAO, discuss a case of a patient with normal-tension glaucoma and progressive visual field loss who is on a regimen of three antiglaucoma medications and has a history of cataract surgery and MIGS. The three physicians review options for next steps and discuss the role of the FSYX Ocular Pressure Adjusting Pump (OPAP, Balance Ophthalmics). They comment on how the technology works to lower IOP and strategies for setting appropriate patient expectations. Later, the patient shares her firsthand experience with the OPAP system.
