  • Title: Enhanced non-contact examination of the vitreous and retina.
    Author: Cavallerano AA, Gutner RK, Semes LP.
    Journal: J Am Optom Assoc; 1994 Apr; 65(4):231-4. PubMed ID: 8014363.
    Abstract:
    BACKGROUND: Fundus biomicroscopy is the clinical standard for comprehensive stereoscopic examination of the posterior segment of the eye. METHODS: Double aspheric hand-held condensing lenses provide excellent stereopsis and a uniformly illuminated wide-field image of the vitreous, retina and choroid. Although there is adequate visualization of vitreous structure, reflectance, and optical lens aberrations, including pupil aberrations, impose limitations on the resolving capabilities of the observation system. RESULTS: Fundus biomicroscopy using the Volk Superfield NC lens provides a superior view of the vitreous structure and a stereoscopic, wide field of view of the structures of the retina and choroid, including a detailed view of the optic disc and macula. CONCLUSIONS: This paper describes the new Volk Superfield NC lens and presents an overview of the high quality imaging capabilities and clinical application of the lens especially with respect to vitreous examination.
