dc.description.abstractPurpose: To investigate the age related changes on the retinal nerve fiber layer thickness (RNFL) and the effects thereof on the standard parameters of Scanner Laser Polarimeter (GDx). Method: 100 cases, examining to the Department of Ophthalmology, School of Medicine, Trakya University, with a refractive error less than 1 diopters in spheric equivalent and a cup/disc rate of less than 0.4, who did not have medii opacity or history of retinal disorder and glaucoma, were included into the study. Following the ophthalmologic examination of all cases, GDx images of both eyes were taken. One eye of each case was selected randomly and the integral values for the total and four quadrants of 100 eyes of the 100 cases were investigated along with the age-related changes in the standard parameters of GDx. Results: Based on the findings from the GDx images of the cases with an age average of 40.68+ 13.08; the quadrant with the thickest peripapillary RNFL was the inferior quadrant, which was followed by the superior, nasal and temporal integral values. Moreover, a negative correlation was determined between age and the'total, superior and inferior integral values (p= 0.008, p= 0.005, p= 0.002). A negative correlation was determined between age and the GDx parameters of maximal modulation (p= 0.044), average thickness (p= 0.008), ellipse average (p= 0.004), superior average (p= 0.002) and inferior average (p= 0.001), and a positive correlation was determined with the number parameter (p= 0.015). Conclusion: The area with the thickest RNFL in the peripapillary area is the inferior quadrant, and the integral values of the total, superior and inferior quadrant are decreased with age while the number parameter is increased.en_US
