En-face optical coherence tomography of unilateral myopic retinoschisis.

A 56-year-old female presented with blurred vision in the right eye. Best corrected visual acuity was 6/18, N12 in the right eye and 6/6, N6 in the left eye. Fundus examination in both eyes showed significant tessellation. Spectral domain OCT revealed a split in the neurosensory retina at the level of Henle's layer nasal to fovea with schitic changes extending to fovea. En face OCT demonstrated a very characteristic half wheel or coral shaped pattern at the level of outer plexiform layer highlighting the complete extent of the retinoschisis [Fig. 1].

(b) Horizontal line scan from Spectral domain OCT centered at fovea at the level of outer plexiform layer demonstrates nasal retinoschisis as a split in the outer retina with schitic changes extending to fovea

En face OCT has significantly improved our understanding about retinal anatomical disorders[1] and is a useful tool in the analysis of the schisis extent and pattern at multiple levels in neurosensory retina.[23]
