The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

The peripheral and Central Humphrey visual field – morphological changes during agingRutkowski, Paul, May, Christian Albrecht 09 November 2017 (has links) (PDF)
Background: To define age-related changes in the visual field by comparing "standard" central and unique peripheral visual field measurements in healthy volunteers.
Methods:
In a single center, retrospective, Cross-sectional, observational study, 20 volunteers with no retinal diseases or risk factors, ranging in age between 30 and 94 years (four age groups: 30’s, 50’s, 70’s, 90’s) were measured in one eye (preferentially the right one) using a Humphrey visual field 24–2 and 60–4.
Results:
While the central visual field remained relatively well preserved during aging showing only a mild reduction in sensitivity, a profound loss of the peripheral visual field was observed beginning in the fifth decade of life and decreasing continuously up to the 90ies.
Conclusions:
The peripheral visual field declined substantially from the 4th decade onward while the central visual field remained quite stable.
