Abstract: Objective To measure the normal macular thickness of the healthy people with the optical coherence tomography (OCT), and analyse the difference among the left eye and right eye, male and female, and the different age. Methods The macular thickness of 80 healthy people were measured with OCT and analyzed statistically. Results and Conclusion The thickness of fovea was (173±13) μm, 95% reference value 148～198 μm. The thickness of region 1 mm arround fovea was (193±13) μm, 95% reference value 168～218 μm. There was no significant difference among left and right eye, male and female, and different age. The thickness of inner ring is thicker than that of outer ring. The thickness of nasal is thicker than that of the temporal side.

Key words: retinal, macula lutea, optical coherence tomography (OCT)
