Custom goniolens enables visualization of trabecular meshwork

NEW ORLEANS — The combination of a custom gonioscopy lens and a commercially available OCT allowed researchers to visualize the iridocorneal angle, according to research presented at Academy ’23.
“The goal was to see more pigment lines when using gonioscopy,” Brett J. King, OD, FAAO, chief of advanced ocular care services at Indiana University School of Optometry, said during the Innovations in Vision and Eye Care program.
“We don’t have a good way of looking at trabecular meshwork in a living person,” King continued. “We tried to build our own gonio lens.”
Researchers designed and constructed a two-mirror goniolens, which was placed on one eye of each participant. For stability, a three-dimensional adjustable mount was attached to the head mount of a Heidelberg Spectralis OCT, according to the study.
The fine detailed structures of the uveal and corneoscleral meshwork were imaged in five eyes of five participants, and thin striations deeper into the trabecular meshwork were visualized.
The researchers concluded that the thin striations may represent the corneoscleral laminae of the trabecular meshwork.
