Evaluating the anterior chamber depth and axis length in high myopia.

Abstract

Objectives: to evaluate the anterior chamber depth (ACD), axis length (AL), and the relationships between ACD and AL in high myopia patients. Objects and methods: a descriptive study was conducted on 168 eyes (88 patients, ≥12 years old) diagnosed with high myopia (more than -6D). Results: the average myopia degree, ACD, and AL were -8.75±2.61D, 3.72±0.20 mm, and 27.33±1.49 mm, respectively. There was no statistical signification between ACD and myopia degree (r=0.044; p>0.05), strong correlation between AL and myopia degree (r=-0.762; p<0.001), and weak correlation between ACD and AL (r=0.165; p<0.05). Conclusion: myopia degree does not relate to ACD, but has a strong correlation to AL. Measuring the AL on high myopia patients is important for the diagnosis, prognosis, and treatment.
