ASCRS 2026: Gonioscopy Still Matters

At the ASCRS Subspecialty Day, Ramya Swamy, MD explained that, despite advances in imaging, direct visualization of the angle remains central to care

1

Gonioscopy remains essential for directly visualizing the iridocorneal angle, despite the rise of advanced imaging techniques.
2

Only 49% of Medicare patients had documented gonioscopy before glaucoma surgery, indicating underutilization of the technique.
3

Experienced ophthalmologists face challenges in performing gonioscopy, particularly in examining all quadrants and during indentation.
4

New handheld imaging devices can enhance gonioscopy but still struggle with capturing consistent, high-quality images across all quadrants.
5

Gonioscopy's direct assessment capabilities are vital for glaucoma care, classification, procedural planning, and identifying secondary pathologies.
