Factors associated with axial length elongation in high myopia in adults

AIM: To investigate the association of axial length (AL) and ocular factors on AL elongation. METHODS: A retrospective chart review patients who underwent two or more examinations for than years. Totally 4 groups were divided according to initial (<24 mm, 24-26 26-28 ≥28 mm). Initial fundus photograph was used find risk associated RESULTS: The mean age 47.21±7.79y. remained almost unchanged in with AL<24 mm 24≤AL<26 mm. On contrary, increased by 0.011 mm/y group 26≤AL<28 0.035 AL≥28 (P<0.001). In high myopia, elongation eye longer (r=0.003, P=0.024), female gender (r=0.014, P=0.019), larger peripapillary chorioretinal atrophic area (r=0.002, smaller vascular arcade angle (r=-0.004, P=0.006). 0.03 myopia (P=0.040), gradually large atrophy (P<0.01). CONCLUSION: elongate significantly AL, gender, photography.
