Hypoplasia of the optic nerve.
Hypoplasia of the optic nerve is uncommon (Scheie and Adler, I94I; Somerville, I962; Whinery and Blodi, I963; Ewald, I967). It is usually due to a failure of development of the ganglion cell layer of the retina and results in a small but discernible optic disc with central vessels. The disc may be cupped with a peripapillary, mottled, yellowish halo corresponding to the size of the normal disc,...
متن کاملHigh-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...
متن کاملOptic Nerve Assessment Using 7-Tesla Magnetic Resonance Imaging.
PURPOSE The purpose of this study was to correlate high-resolution magnetic resonance imaging (MRI) and histologic findings in a case of juxtapapillary choroidal melanoma with clinical evidence of optic nerve invasion. METHODS With institutional review board approval, an enucleated globe with choroidal melanoma and optic nerve invasion was imaged using a 7-tesla MRI followed by histopathologi...
