Tests to diagnose glaucoma include (besides tonometry) Gonioscopy ***Not present in primary care facilities (use of a special lens to see the outflow channels of the angle) rule out angle-closure or secondary causes of IOP elevation, such as angle recession or pigmentary glaucoma Pupillary reflex response- The pupil size should be documented at each testing session, as constriction can reduce retinal sensitivity and mimic progressive field loss.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
