SWEPT SOURCE OPTICAL COHERENCE TOMOGRAPHY VALIDATES LAMINA CRIBROSA ANOMALY IN OPTIC DISK PIT.

PURPOSE: Swept Source Optical Coherence Tomography validates lamina cribrosa anomaly in optic disk pit.

METHOD: Observational case report.

RESULTS

A 25-year-old African American male presented with decreased vision in right eye of 4 days duration. Best corrected visual acuity (BCVA) for distance in right eye was 20/200 and in left eye was 20/20. Dilated fundus examination of right eye showed serous macular detachment of entire posterior pole along with an optic pit on temporal margin of optic disk. En-face image of the optic disk on Swept source OCT (SS-OCT) confirmed defect in the lamina cribrosa in the right eye.

CONCLUSION

Congenital optic disk pit a birth defect in lamina cribrosa is a rare, visually impairing disorder. Spectral domain optical coherence tomography (SD-OCT) scan showed neurosensory detachment, however, lamina cribrosa defects are not delineated with it. SS-OCT a recent advance in scanning technology allows superior resolution of optic disk and confirms the anomaly of lamina cribrosa.
