Abstract

Objectives: This study investigated the retinal layer thickness, choroidal thickness (CT), and retinal nerve fiber layer (RNFL) parameters in 3 refractive groups.

Methods: A total of 201 eyes of 201 subjects were enrolled in this prospective and comparative study. The patients were divided into 3 groups according to refractive status: Group 1 consisted of 60 eyes of myopic subjects, Group 2 comprised 72 eyes of emmetropic subjects, and 69 eyes of hyperopic subjects were categorized as Group 3. The retinal layer thickness, CT, and RNFL parameters were measured using optical coherence tomography and compared between groups.

Results: The mean age of the patients was 22.33±10.11 years in Group 1, 21.55±8.3 years in Group 2, and 23.73±11.08 years in Group 3 (p=0.741). Group 1 consisted of 34 women and 26 men, Group 2 contained 44 women and 28 men, and Group 3 was made up of 45 women and 24 men (p=0.124). The mean spherical equivalent value was -6.16±2.01 D in Group 1, 0.13±0.5 D in Group 2, and 5.48±1.32 D in Group 3 (p<0.001). The RNFL and macular thickness values were lower in the myopic patients compared with those of the other groups (p<0.05). The CT measurement was lower in the myopic patients and higher in the hyperopic patients compared with the emmetropic patients (p<0.05).

Conclusion: The myopic patients had a lower CT and RNFL thickness measurement than the emmetropic and hyperopic patients, whereas the hyperopic patients had a higher CT than the other patient types.

Keywords: Choroidal thickness; emmetropia; hyperopia; myopia; retinal nerve fiber layer.
