Electrophysiologic Testing in Disorders of the Retina, Optic Nerve, and Visual Pathway

Disorders of Optic Nerve and Visual Pathways

the role of visual aids and translation in teaching vocabulary in est

the present study investigated the effect of the two vocabulary teaching techniques in est, namely the use of translation and the use of visual aids as two separate vocabulary teaching techniques. to answer the question of the study, a pretest (michigan test) was administered to the 58 randomly selected est students at khajeh nasiredin tusi university, faculty of mechanics. after the homogeneit...

Development of the retina and optic pathway

Our understanding of the development of the retina and visual pathways has seen enormous advances during the past 25years. New imaging technologies, coupled with advances in molecular biology, have permitted a fuller appreciation of the histotypical events associated with proliferation, fate determination, migration, differentiation, pathway navigation, target innervation, synaptogenesis and ce...

Anterograde Degeneration along the Visual Pathway after Optic Nerve Injury

PURPOSE To investigate anterograde degenerative changes along the visual pathway in a rat model of optic nerve axotomy. METHODS Optic nerve transection was performed in adult Sprague-Dawley rats. Animals were sacrificed at regular time intervals and tissues harvested. Immunoblotting followed by densitometric analysis was used to determine the phosphorylation profile of Akt in the dorsal later...

High-Resolution Imaging of the Optic Nerve and Retina in Optic Nerve Hypoplasia

PURPOSE To investigate the optic nerve and macular morphology in patients with optic nerve hypoplasia (ONH) using spectral-domain optical coherence tomography (SD OCT). DESIGN Prospective, cross-sectional, observational study. SUBJECTS A total of 16 participants with ONH (10 female and 6 male; mean age, 17.2 years; 6 bilateral involvement) and 32 gender-, age-, ethnicity-, and refraction-ma...
