Abstract

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.
