Histological Section as Compared to the OCT Image Although the photoreceptor integrity line, or the PIL (defined as the junction between the inner and outer segments) is barely visible in most histological sections, it is highly prominent in normal SD OCTs. The PIL, as shown above, should be continuous throughout the entire scan in normal

SD-OCT through the fovea of the left eye All OCT sections within the posterior pole are normal. The photoreceptor integrity line (see page 16) is intact and correlates with the 20/20 VA OD
