Quantitative measurements of retinal morphological changes associated with acute branch retinal vein occlusion with optical coherence tomography.

<p>On the vertical section through the foveal center, the inner (yellow arrows), outer (blue arrows), and total (red arrows) retinal thickness was measured at 1 mm, 2 mm, and 3 mm from the center of the fovea toward the affected side of the retina, respectively. The maximum thickness of the inner, outer, or total retina was determined as the largest among the three measurements.
