ABSTRACT

Objective: To identify the distribution of the anterior chamber depth in phakic subjects using optical coherence tomography and compare it with the reported in our media (3.22 mm), considering the iridocorneal angle width. Design: non-experimental, descriptive, cross-sectional, prospective study. Ambit: population from Mexico City and its metropolitan area. Participants: phakic subjects aged 40 to 85 years, from any gender, who had a transparent cornea and accepted to participate in the study. Intervention: variable measurement with anterior segment optical coherence tomography. Main outcome variables: mean and 95% confidence intervals (C.I.) of the anterior chamber depth and iridocorneal angle width with optical coherence tomography; we compared the chamber depth between genders (Student’s t) and age groups (ANOVA). Results: 145 eyes, 108 from females (74.5%), mean age 50.9 ± 15.37 years. Mean anterior chamber depth was 2.72 ± 0.42 mm (95% C.I. 2.65-2.79), mean nasal iridocorneal angle width was 31.29 ± 6.6^o (95% C.I. 30.22-32.36) and mean temporal iridocorneal angle width was 32.25 ± 7.02^o (95% C.I. 31.11-33.39). The anterior chamber depth did not differ between genders or age groups. Conclusions: The anterior chamber depth is lower than the reported, although iridocorneal angles are wide as an average; both variables should be considered together to estimate their value as predictors in anterior segment pathology.
