Documentation of optic nerve pit with macular schisis-like cavity by spectral domain OCT.

The authors report using spectral domain optical coherence tomography (OCT) to observe a patient with an optic nerve pit and macular schisis-like spaces. An 8-microm axial resolution prototype spectral domain OCT and stereo fundus photography were used to observe the patient. A macular schisis-like cavity was present at baseline and additional cystic changes developed in the nerve fiber layer over a period of 16 months; however, the visual acuity remained stable at 20/20. Spectral domain OCT provides greater detail of the changes in morphology and structure of macular schisis and edema associated with an optic nerve pit.
