PURPOSE: The purpose of this study was to investigate the deep structural abnormalities in the patients with morning glory syndrome by using swept source optical coherence tomography.
METHODS: The papillary and peripapillary areas of the four eyes (four patients) with morning glory syndrome were examined with a prototype swept source optical coherence tomography system with a center wavelength of 1,050 nm. In particular, the abnormalities of the lamina cribrosa and peripapillary sclera were evaluated.
RESULTS: The lamina cribrosa was posteriorly displaced in all the four eyes, and the disk area was filled with herniated retinal tissue. A bump-like protrusion near the papillary margin or within the cup area was observed in three eyes. Some tissues were observed to exist between the retina and the sclera surrounding the papillary margin annularly. In one case, swept source optical coherence tomography detected intrascleral adipose tissue in a relatively wide area around the fovea and the optic nerve.
CONCLUSION: Swept source optical coherence tomography clearly delineated the papillary and peripapillary abnormalities of morning glory syndrome. Scleral structural abnormalities were present outside the optic nerve as well.
