Background: Reports of tumor-related anterior visual pathway blindness that have resolved after surgical decompression are rare. The longest reported duration of tumor-related blindness completely reversed by optic nerve decompression is 3 days. We describe a pediatric patient with 7 days of no light perception who experienced reversal of blindness following tumor resection and optic nerve decompression.
Case Description: A 33-month-old boy presented with a 4-day history of no light perception. Magnetic resonance imaging revealed a mass involving the sphenoid sinus, sella turcica, and clivus with significant optic nerve involvement. Loss of light perception and complete absence of a pupillary light reflex were documented for the next 72 h. A sluggish pupillary light reflex was regained 24 h after instituting intravenous steroids. An urgent bi-frontal craniotomy and optic nerve decompression were performed 7 days after the onset of blindness. Surgical pathology revealed metastatic neuroblastoma. Eleven days after optic nerve decompression, the child was able to count fingers and recognize faces and printed book characters.
Conclusion: Prolonged blindness secondary to tumor-related optic nerve compression may be reversible up to 1 week from onset in children presenting with no light perception.

Risk factors for visual loss after excision of orbital cavernous venous malformations: a systematic review.

Background: Orbital cavernous venous malformations (OCVMs) are the most common primary orbital mass lesion and presenting symptoms are usually secondary to a mass effect. Surgical excision presents unique challenges and vision loss is a rare, but devastating, complication. This review aims to identify risk factors for vision loss with excision of OCVMs.

Purpose: To evaluate the safety and efficacy of fibrin glue in preventing early recurrence of vitreous haemorrhage following surgery for proliferative diabetic retinopathy (PDR).
Design: Single masked randomized-controlled clinical trial SUBJECTS: Consecutive patients with vitreous haemorrhage due to PDR undergoing primary vitreoretinal surgery were screened. After completing all vitreoretinal manoeuvres including endo-cautery to bleeders, infusion pressure was gradually reduced to 5 mmHg.

Despite tremendous progress in characterizing the myriad cellular structures in the nervous system, a full appreciation of the interdependent and intricate interactions between these structures is as yet unfulfilled. Indeed, few more so than the interaction between the myelin internode and its ensheathed axon. More than a half-century after the ultrastructural characterization of this axomyelin unit, we lack a reliable understanding of the physiological properties, the significance and consequence of pathobiological processes, and the means to gauge success or failure of interventions designed to mitigate disease.

A 45-year-old healthy African-American man experienced 2 months of right-eye soreness followed by acute onset of right painful vision loss with binocular, oblique diplopia. Visual acuity was count fingers OD and 20/20 OS. He had a partial, right, pupil-involving cranial nerve III palsy with a right relative afferent pupillary defect and optic disc edema with tortuous vessels.

Objective: Elevated intracranial pressure (ICP), a common complication in traumatic brain injuries (TBI), can lead to optic nerve sheath diameter (ONSD) enlargement and flow spectrum changes from the internal carotid artery (ICA) to middle cerebral artery (MCA). This study will investigate the use of Cervical-Cerebral Arterial Ultrasound (CCAU) for non-invasive ICP assessment and evaluating the related indices' clinical utility in TBI patients with decompressive craniotomy (DC).
Methods: ONSD and flow spectrum changes were measured within 24 h after DC in 106 patients via ultrasonic ONSD measurement and CCAU, simultaneously.
