Purpose: The evaluation of choroid becomes possible after the developments in the technology of optic coherence tomography (OCT). In this study we aimed to evaluate central macular and choroidal thickness in myopic subjects with spectraldomain optical coherence tomography (SD-OCT). Materials and Methods: After complete ophthalmological examination, a hundred and seventy six eyes of 88 subjects with no retinal or choroidal disease except myopia, underwent scanning with SD-OCT for the measurements of central macular and choroidal thickness. Five groups were formed according to the spherical equivalent calculations of the refraction as follows: Group 1 (Controls): Between 0.00 and -0.75 D; Group 2: -1.00 and -3.00 D; Group 3: -3.25 and -6.00 D; Group 4: -6.25 and -10.00 D and Group 5: over -10.25 D. Results: The evaluation of anterior segment and the measurement of intraocular pressure were within normal limits in all of the subjects. When the mean central macular thickness measurements were analysed, there was a statistically significant difference between group 5 compared with the other four groups. However, when the mean central choroidal thickness measurements were analysed, we found a statistically significant difference between all of the groups (p<0.05). Conclusion: Central macular and choroidal thickness may vary in some ocular pathologies. In this study, the thickness of the macula and choroid were found to be decreased with the increasing degree of myopia. The degree of myopia should be considered when evaluating macular and choroidal thickness in the studies.
