Bilateral Posterior Ischemic Optic Neuropathy Due to Bilateral Anterior-Drainage Dural Carotid-Cavernous Fistulas: A Case Report.

Purpose: To report a case of bilateral posterior ischemic optic neuropathy (PION) due to bilateral anterior-drainage dural carotid-cavernous fistulas (CCFs).

Case Description: We report on a 62-year-old woman with a history of poorly controlled hypertension who presented with sudden bilateral visual loss and headache for 5 days. She denied a history of head trauma.

Preoperative Peripapillary Retinal Nerve Fiber Layer Thickness as the Prognostic Factor of Postoperative Visual Functions After Endoscopic Transsphenoidal Surgery for Pituitary Adenoma.

Purpose: To evaluate the prognostic ability of preoperative peripapillary retinal nerve fiber layer thickness (pRNFLT) for predicting postoperative visual functions, including the visual field index (VFI) and visual acuity (VA), of subjects with pituitary adenoma (PA) who were treated with endoscopic transsphenoidal surgery for pituitary adenoma (ETSS-PA) exclusively.

Subjects And Methods: This 11-year retrospective study was performed at a single institution in Thailand. Sixty-six eyes of 33 subjects who had a PA compressing the anterior visual pathway and were treated with ETSS-PA alone were included.
