In this presentation from Glaucoma Subspecialty Day 2022, Dr. Thomas Samuelson reviews the glaucoma surgical landscape through the arrival of minimally invasive glaucoma surgery (MIGS). While the efficacy of traditional surgery was never in doubt, safer glaucoma surgery was an unmet need for decades. Despite initial skepticism, MIGS has now become mainstream among both comprehensive ophthalmologists and glaucoma specialists. Dr. Samuelson discusses trabs and tubes, the Collaborative Initial Glaucoma Treatment Study (CIGTS), the decoupling of cataract surgery and trabeculectomy, and risk mitigation, among other topics.
