Following preliminary studies on human optic nerve head lesions in the aged, 109 optic nerve heads were examined to determine the frequency, localisation, and time of appearance of the two types of senile degenerative lesions described in these initial studies. Frequency curves are presented, and results discussed and compared with data reported in the published literature.

Risk factors for visual loss after excision of orbital cavernous venous malformations: a systematic review.
Br J Ophthalmol
January 2025
Department of Ophthalmology, Royal Adelaide Hospital, Adelaide, South Australia, Australia.
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.
