The Nasal Coastline of Traquair’s Island: The Influence of Gaze Direction on the Recorded Nasal Visual Field
Journal Title: Journal of Ophthalmology and Advance Research - Year 2020, Vol 1, Issue 1
Abstract
Objective: In a pilot study to evaluate the importance of the nose for the definitive size and shape of the nasal visual field. Methods: Six eye-healthy individuals aged 12-59 years volunteered for regular bilateral assessment by kinetic Goldmann perimetry, which was compared with recordings performed after changing access from visual space by monocular horizontal shifts of fixation. Results: Despite increased visual access at lateral fixation the nasal visual span uniformly maintained its size. Conclusion: Establishing the definitive visual field seems to be part of a toddler’s development of full visual function, as apparently based on an interplay between visual input and functional maturation. A scant literature supports it as being close to adult norm already from the age of 6-12 months, and not restricted on its way to full field by periocular facial contours, as often forwarded in literature of the past.
