NEW OPPORTUNITIES OF MONITORING PATIENTS WITH MYOPIA

Abstract

Purpose: to study the changes of axial length and distension of the posterior pole retina of the eye in patients with myopia, using two optical methods: contactless biometrics and optical coherence tomography (OCT). Material and methods. We conducted a combined clinical and instrumental examination of 83 patients (166 eyes) with low and moderate myopia aged 10-19 (ave. 13.8 ± 2.5 years). The examination included the measurement of axial length, using a Lenstar contactless laser biometer Lenstar, and retinal nerve fiber layer (RNFL) thickness using optical coherent tomography (OCT Stratus). 32 patients (64 eyes) with emmetropia aged 7 to 18 (ave. 11.7 ± 2.6 years) served as control. Results. The analysis of contactless biometrics and OCT results collected for 1 year helped specify four clinical groups: Myopia progression, Latent myopia progression, Myopic refractogenesis, and Stable myopia. It was also found that RNFL thickness in different retinal sectors is decreasing unevenly in latent myopia progression. To facilitate the evaluation of myopia progression, a structural indicator of progression was proposed. Conclusion. Progressing myopia monitoring by two modern optical methods: biometrics (for AL) and OCT (for RNFL thickness) enables the detection of changes in the fibrous eye capsule and identification of individual features of myopic progression.
