Objectives: To evaluate choroidal thickness in myopia and to correlate it with axial length, age and spherical equivalent.
Patients and methods: A prospective study of 40 eyes of 40 myopic patients was performed from July 2017 to February 2018 at Qena University Hospital. Choroidal thickness was measured using SD-OCT.
Patients were divided to two groups group A(<-6 D) and group B(>-6 D).
Results: Our study demonstrated differences between group A and group B, with respect to choroidal thickness, axial length and spherical equivalent. The mean SE was -3.2± 2.29 D (range,-0.25 to -6) in group A and -10.2±3.75 D (range,-6.5 to -16) in group B. The mean AL was 23.56±0.42 mm (range,22.6 to 24 mm) in group A and 26.56± 1.64 mm (range,23.7 to 28.8 mm) in group B. The mean CT was 190± 65.16 μm (range,107- 331 μm) in group A and 161.9± 97.338 μm (range, 40- 391 μm) in group B (P=0.00123). The mean SFCT was 206.7±66.7 μm (range,111-331 μm) in group A and 158.4± 39.16μm (range,43- 345 μm) in group B (P=0.0002). The BCVA was changed logMAR scale, with an average 0.858±0.35 and 0.65±0.287 in group A and B respectively.
Conclusion: Choroidal thickness was significantly lower in high myopic eyes at different locations. As age, spherical equivalent, and axial length increase the choroidal thickness decreases. |
