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

The extreme slope of the sections towards the disc is due to the posterior staphyloma which is greater toward the disc than around the macula. The green box is 6 mm x 6 mm and contains 128 horizontal sections. Note: Compare these abnormal OCT scans to the normal OCT image on the next page. Specifically,

The 5 line vertical raster scans (high resolution) reveal cystoid spaces and several retinal splits (schisis) inferior to the optic nerve head and an epiretinal membrane superior to the optic nerve head. The magnified scan below corresponds to the blue vertical line in the fundus image to the left. The four other scans represent

The 5 line horizontal raster scans (high resolution) reveal cystoid spaces in the macula. However, the VA is 20/20 and the patient is asymptomatic. The magnified scan below corresponds to the blue horizontal line in the fundus image to the left. The four other scans represent the green horizontal lines as indicated.
