    Clinical review of retinotopy - 10 month(s) ago

    Two observations made 29 years apart are the cornerstones of this review on the contributions of Dr Gordon T. Plant to understanding pathology affecting the optic nerve. The first observation laid the anatomical basis in 1990 for the interpretation of optical coherence tomography (OCT) findings in 2009. Retinal OCT offers clinicians detailed in vivo structural imaging of individual retinal…

    Decussating axons segregate within the anterior core of the primate optic chiasm - 10 month(s) ago

    Background The axons of ganglion cells in the nasal retina decussate at the optic chiasm. It is unclear why tumours cause more injury to crossing nasal fibres, thereby giving rise to temporal visual field loss in each eye. To address this issue, the course of fibres through the optic chiasm was examined following injection of a different fluorescent tracer into each eye of a monkey. Methods…

      Why do #sellar #tumors tend to lead to temporal visual field loss? A study by #USCF #ophthalmology proposes that compressed decussating axons within the #optic #chiasm by these tumors may provide an explanation in primates.

    Vascular supply of the optic nerve head: implications for optic disc ischaemia - 10 month(s) ago

    The vascular supply of the optic nerve head is complex and remains incompletely delineated. Over the past 50 years, various investigators have attempted to clarify the relative contributions of the choroid, the short posterior ciliary arteries and the central retinal artery to the vascular beds of the inner retinal, prelaminar, laminar and retrolaminar segments of the nerve head. Conflicting…

      Happy Monday! We continue our #neuroophthalmology series this month with Dr. Anthony Arnold's discussion on the vascular implications of #ischemic #optic #neuropathy. What role does vascular density play in eye diseases like #NAION? Read more here: https://t.co/hDjBSldEAY https://t.co/DonlbD0PnN

    Red Desaturation Prevalence and Severity in Healthy Patients - 2 year(s) ago

    Background and Objectives To determine the percentage of the healthy population that responds asymmetrically to the red desaturation test and to approximate the degree of red desaturation in those individuals. We also sought to elucidate any correlation between demographic variables and red desaturation prevalence and severity. Methods Adults aged 18 years and older with a normal eye…
