Factors Associated with the Clinical Course of Vitreomacular Traction

Figure 1

Time-domain optical coherence tomography of a patient with vitreomacular traction. The nasal angle is measured in this case by using the NIH image tool ImageJ. The white lines define the measurement of the vitreofoveal angle (θ). A line parallel to the RPE and another line tangential to the posterior hyaloid at the point of adhesion are traced. The angle between the two lines is measured.
