Purpose: To evaluate the structure of optic nerve pits and determine if a communication between the nerve and any macular detachment could be appreciated using a combination of coronal and longitudinal images obtained with the OCT/SLO. Methods: OCT/SLO is a new technology which offers the opportunity to image the retina and the optic nerve in vivo by producing coronal (C–scan) OCT and confocal SLO views as well as longitudinal (B–scan) OCT cross–sections at high resolution. Images were obtained centered on the pit, peripapillary retina, and macula in 4 eyes of 4 patients. Data from these images were analyzed to see if the communication between the optic pit and retinal fluid could be determined. Results: Sequences of coronal sections through the optic pit and associated subretinal and/or schisis cavity fluid collections demonstrated distinct pathways of communication in 4 out of 4 patients. In addition, internal aspects of optic pit morphology, including bifurcation and loculation, was seen in progressively deeper sections through the nerve. Conclusions: OCT/SLO is a unique technology which can provide detailed surface views along with coronal and longitudinal cross–sections of the retina and optic nerve. These views can yield information not available with conventional OCT which may help to unravel the complex anatomy and pathophysiology of this condition.
