Relationship between Anterior chamber volume, angle, depth with myopia by Oculyzer

Clinical observations and previous studies have shown an inverse relationship between refractive error and anterior chamber depth. The aim of this study is to assess the relationship between the amount of myopia with anterior chamber parameters such as volume, angle, depth and the difference in these parameters between genders.

In this descriptive-analytic study, 83 refractive surgery candidates (-0.5 to -9) aged between 20-40who have undergone Oculyzer photography were investigated. Statistical analysis of data extracted from patient's files performed using spss18 and relation between variables were assessed by Pearson or Spearman correlation coefficient. T-test for comparison of variables or the nonparametric equivalent (Mann-Whitney) was used.

In this group there was no statisticaly significant correlation between anterior chamber volume(P=0.611, r =0.057), angle(P= 0.780, r=- 0.031), depth(P= 0.944, r=0.008) and refractive error. In comparison between genders, correlation between anterior chamber volume and depth mean differences was statistically significant (P<0.0005) but there was no statistical significant correlation between anterior chamber angle mean differences(P= 0.064)

This study shows that in myopic patients aged 20-40 years, there is no significant correlation between anterior chamber volume, angle, depth and amount of refractive error.
