A classic temporal optic disc pit showing progression in the corresponding optic nerve fiber and visual field defects

We report a rare case with a classic temporal optic disc pit (ODP) showing the progression of an associated nerve fiber layer defect (NFLD) with the corresponding visual field defect (VFD).
We describe the patient’s medical records and review the pertinent literature.
A 54-year-old woman had a temporal ODP, which was considered to be congenital, associated with both NFLD expanded to both the upper and lower sides of the horizontal line and corresponding VFD and a small ODP-like excavation at the 6.5 o’clock position on the disc edge with a narrow NFLD OD. During the 5-year follow-up period, both the NFLD and VFD associated with the temporal pit progressed without serous retinal detachment. The small ODP-like excavation located at the 6.5 o’clock position also showed progressive NFLD in the temporal lower quadrant with advanced VFD, which suggested that the excavation might be associated with glaucoma.
Based on the observation that the VFD occupied the two temporal quadrants with no step, an NFLD with corresponding VFD associated with a classic temporal ODP, although not considered to be related to glaucoma, can progress.
