Use of MP-1 microperimetry in optic disc pit and secondary retinoschisis.

The optic nerve head pit is a congenital anomaly of the optic disc due to imperfect closure of the superior edge of the embryonic fissure. We studied in detail by means of fluorescein angiography (FLA), microperimetry (fundus related perimetry), and ocular coherence tomography (OCT) the case of a 30-year-old woman who had an optic pit with secondary retinoschisis in her right eye.
