Abstract Details
Purpose:
To determine the relationship between contrast sensitivity, ocular dominance and macular pigment optic density in healthy young adults.
Setting:
Ophthalmology Clinic of Afyon Kocatepe University Hospital
Methods:
39 patients between the ages of 18-30 who applied to the Ophthalmology Clinic of Afyon Kocatepe University Hospital; 78 emetropic eyes with complete visual acuity were included in the study.
In each case, the dominant eye was detected with the Dolman method (hole-in-the-card test).
Using the MonPackONE vision monitor system (Metrovision, Perenchies, France), macular pigment optical density (MPOD) test and dynamic photopic contrast sensitivity test (0.5, 1, 2, 6 and 12 cycles per degree) were performed.
Results:
The mean age of the 19 male and 20 female patients included in our study was 24.23 ± 1.67. The mean MPOD of the cases was found to be 5.41 ± 1.91 dB. Mean contrast sensitivity values were 18 ± 1.98 at 0.5 cpd, 20.42 ± 1.93 at 1 cpd, 20.92 ± 2.38 at 2 cpd, 18.05 ± 3.67 at 6 cpd, and 11.27 ± 3.66 at 12 cpd. In the photopic contrast sensitivity test performed in dominant eyes, the mean 1, 6, and 12 cpd values were statistically significantly higher than non-dominant eyes (respectively (p: 0.025), (p: 0.013), (p: 0.032)). No statistically significant difference was found between dominant and non-dominant eyes in terms of MPOD (p> 0.05). There was no statistically significant difference between male and female genders in terms of contrast sensitivity test parameters and MPOD (p> 0.05). No statistically significant correlation was found between contrast sensitivity parameters and MPOD (p> 0.05, Spearman).
Conclusions:
We think that the concepts of ocular dominance and contrast sensitivity are conditions that affect each other in humans.
