摘要
Purpose: To study the relationship between age-related maculopathy (ARM)/age -related macular degeneration (AMD) and phakic refraction and between ARM/AMD a nd axial length. Methods: The study was a point prevalence study that included 6 63 randomly selected persons aged over 65 years. We measured axial length and re fraction. Fundus images were graded for ARM according to a modified Wisconsin Ag e-related Maculopathy Grading System standard. Data from both eyes were availab le from most participants. We analysed the results for both individual eyes and pairs. Results: The mean axial length was 23.22mm for right eyes and 23.21mm for left eyes. Women had a 0.57-mm shorter mean axial length than men. The mean re fraction was +1.0 dioptres (D) for right eyes and +0.9 D for left eyes. At 70 years of age women were more hypermetropic than men by 0.66 D. There was no sign ificant difference in refraction or axial length among the groups with different ARM stages. Conclusion: We found no statistically significant relationship betw een axial length/refraction and AMD/ARM. There was a statistically significant s ex difference in axial length and refraction, where women had shorter axial leng ths and were more hypermetropic than men.
