Retinal structure, including presence of photoreceptors, was preserved only in the far periphery.

Histopathologic study revealed rods and cones without outer segments in the macula and far periphery.

Generally, the cell area and shape was relatively constant and regular except in the far periphery.

We also found a trend toward increasing cell area and eccentricity with age in the macula and the far periphery.

Those uncertainties make BES a punt -but also a test of how far periphery bulls are prepared to go.

Measurements were taken from selected areas spanning the length of the temporal retina through the macula and the mid-periphery to the far periphery.

Pericentral retinitis pigmentosa (RP) is an atypical form of RP that affects the near-peripheral retina first and tends to spare the far periphery.
