OCT and OCT Angiography in Glaucoma
Speakers: Greg Caldwell, OD, FAAO
Hours: 2hrs | 94801-GL

See Course Description

Optical Coherence Tomography (OCT) has established itself as a must have imaging technique in any optometric practice setting due to its exceptional anatomical and structural information. Using OCT for the diagnosis, treatment, and management of glaucoma is indispensable. OCT Angiography (OCT-A) was recently introduced to the optometric market, and using OCT-A is becoming equally important in the diagnosis, treatment, and management of glaucoma. This course will show how to interpret and integrate OCT and OCT-A in glaucoma diagnosis, treatment, and management.
