Abstract Details

Purpose:

to determine the correlation between the degree of myopia and axial length (AL) with choroidal thickness (CT).

Setting:

Hasanuddin university hospital, Makassar, South Sulawesi, Indonesia

Methods:

The participant examined with retinoscope to obtained the best corrected visual acuity based on spherical equivalent. The degree of myopia was classified into low, moderate, high respectively. AL measured using A-scan Ultrasound, and was divided into short, moderate and long, respectively. CT was measured perpendicularly from the outer edge of the retinal pigment epithelium (RPE) to the choroid-scleral interface in 9 areas according to early treatment diabetic retinopathy study (ETDRS) using spectral domain optical coherence tomography (SD-OCT).

Results:

Multivariate analysis for the degree of myopia and the axial length obtained insignificant correlation in temporal (p=0,076) and superior (p= 0,074) respectively. However, univariate analysis revealed significant correlation in all areas for the degree of myopia (r= -0,230 – (- 0,407), p= < 0,001 – 0,004) and also the axial length (r= -0,270 – (- 0,453), p=<0,001 – 0,003).

Conclusions:

Axial length had a greater correlation with the choroidal thickness compared to the myopia degree
