COMPARISON OF ANTERİOR AND POSTERIOR SEGMENT PARAMETERS ACCORDING TO IRIS COLOR SPECTRUM

Abstract

Aim: Comparison of eye anterior and posterior segment parameters according to iris color Methods: 150 eyes of 150 patients who applied to Aksaray Training and Research Hospital between 2019-2020 were included in the study. 28 blue, 30 green, 29 light brown (light pigmentation), 31 medium brown (medium pigmentation) and 30 dark brown (heavy pigmentation)eyes, 5 groups of patients were included in the study. Biomicroscopy and fundus examination were performed on the patients. After measuring the refraction of the patients, corneal topography and optical biometry, Intraocular Pressure (IOP), Central Corneal Thickness (CCT), Anterior Chamber Depth (ACD), Anterior Chamber Angle (ACA), Lens Thickness (LK), Axial Length (AU) Retinal nerve fiber thickness (RSLK), central retinal thickness (CRC) and subfoveal choroidal thickness (SFKK) measurements were made with OCT. Results: The mean age of the patients was 33.4 ±5.5, 35.7±4.7, and 32.9 ±6.7 in patients with blue, green and brown eyes, respectively. There were 15 women and 13 men in the blueeyed group, 16 women and 14 men in the green-eyed group, and 47 men and 43 women in the brown-eyed group. In terms of anterior and posterior segment parameters, a difference was found between blue eyes and brown eyes in terms of CCT, ACD and LK (p=0.035, 0.004 and 0.012). A difference was found between blue eyes and green eyes in terms of ACD and LK (p=0.006 and 0.041). There was no significant difference between the anterior and posterior segment parameters of the green-eyed and brown-eyed patients. In addition, there was no difference between the groups in terms of other factors (p>0.05). As a result of the correlation analysis performed in terms of parameters according to iris pigmentation level, no positive or negative correlation was found with any parameter (p>0.05). Conclusions:When evaluating patients, it should be kept in mind that the normal values of some eye parameters may vary according to the differences in iris color.
