A sticky situation

An 81-year-old man with bilateral progressively blurry vision and optic disc swelling was referred for evaluation. Examination and ancillary testing confirmed a diagnosis of bilateral vitreopapillary traction accompanied by unilateral tractional retinoschisis in the right eye. Pars plana vitrectomy was performed to release the traction in both the eyes. Visual acuity improved in the right eye and stabilized in the left eye. Retinoschisis in the right eye resolved. The visual field improved in both the eyes although the left eye demonstrated a persistent hemifield defect likely attributable to a prior optic neuropathy. Distinguishing vitreopapillary traction optic neuropathy from nonarteritic anterior ischemic optic neuropathy is discussed.
