Abstract:
To measure the subfoveal choroidal thickness ( SFCT ) in myopia using Cirrus HD optical coherence tomography ( OCT ), and to explore the relationship between the SFCT, axial length and myopic refractive spherical equivalent.
● METHODS: One - hundred thirty - three eyes of 70 healthy volunteers were recruited, and were divided into emmetropia group, low- degree myopia, middle- degree myopia and high - degree myopia group. SFCT were measured by Cirrus HD OCT, and the relationship between the SFCT, axial length and myopic refractive spherical equivalent were evaluated.
●RESULTS: 1) Average SFCT was (275. 91±55. 74)μ m in normals, that in emmetropia group, low-degree myopia, middle- degree myopia and high - degree myopia group were (290. 03± 34. 82) μ m, (287. 64 ± 51. 51) μ m, (274. 95 ± 56. 83)μ m, (248. 37 ± 67. 98) μ m; 2) the SFCT of high -degree myopia group was significant thinner than that of emmetropia group (P< 0. 05); 3) There was a significant negatives correlation between the SFCT and axial length (P<0. 01), a significant positive correlation between SFCT and myopic refractive spherical equivalent (P<0. 01).
● CONCLUSlON: the SFCT is inversely correlated with increasing axial length and myopic refractive error.
