ABSTRACT
Purpose. To evaluate the variations in macular thickness in young Chinese myopic persons and the association with axial length (AL), spherical equivalence refraction (SE), age, intraocular pressure, and sex. Methods. In total, 133 young Chinese myopic subjects between 18 and 30 years of age were selected. The macular thickness was assessed using third-generation optical coherence tomography. AL, intraocular pressure, and SE were also measured. Results. The mean central foveal thickness was 191.1 ± 15.3 µm. The macula was consistently thinner in women than in men. Central foveal thickness had a significant positive correlation with AL and a negative correlation with SE. In the inner and outer regions, the macular thickness had a positive correlation with SE and negative correlation with AL. Conclusions. The retina was thinner in women than in men. Associated with myopic progression and AL extension, the central foveal thickness increased, while the retinal thickness of the inner and outer regions decreased.

Macular map, automatically divided into nine Early Treatment Diabetic Retinopathy Study (ETDRS) sectors. F, foveola; TI, temporal inner sector; SI, superior inner sector; NI, nasal inner sector; II, inferior inner sector; TO, temporal outer sector; SO, superior outer sector; NO, nasal outer sector; and IO; inferior outer sector. Areas TI, SI, NI, and II form the inner region; areas TO, SO, NO, and IO form the outer region.

fig1: Macular map, automatically divided into nine Early Treatment Diabetic Retinopathy Study (ETDRS) sectors. F, foveola; TI, temporal inner sector; SI, superior inner sector; NI, nasal inner sector; II, inferior inner sector; TO, temporal outer sector; SO, superior outer sector; NO, nasal outer sector; and IO; inferior outer sector. Areas TI, SI, NI, and II form the inner region; areas TO, SO, NO, and IO form the outer region.

Mentions: The mean retinal thicknesses were determined for nine sectors, as defined by the Early Treatment Diabetic Retinopathy Study (ETDRS) (Figure 1). The ETDRS areas included three concentric circles with diameters of 1, 3, and 6 mm; a central 1 mm circle represented the foveal area and inner and outer rings of 3 and 6 mm diameter, respectively. Each ring was divided into four quadrants: superior, nasal, inferior, and temporal. In this study, only the scans with signal strengths of at least six were analyzed. All measurements were taken by a single, trained examiner.
