Myopia Management in Hong Kong.

Objectives: We aimed to investigate how optometrists in Hong Kong are managing myopic and "pre-myopic" children. Methods: Clinical files for children aged 6 to 10 years old who had eye examinations from 2017 to 2021 were retrospectively reviewed. Children were grouped by the initial spherical equivalent refractive error (SER) as myopes or pre-myopes. The demographic data, refractive error, and myopia management recommended by the optometrists were analyzed. Results: A total of 1,318 children (859 myopes and 459 pre-myopes) from ten clinics in Hong Kong were included. Over 5 years, myopia management recommendations shifted significantly (p < 0.001). In 2017, only 18.4% of children were recommended to pursue myopia control (MC), increasing to 42.8% by 2021. The use of MC spectacle lenses increased from 7.3% in 2017 to 36.8% in 2021, becoming the most recommended option. Orthokeratology, MC contact lenses, and atropine remained stable at less than 5% over this period. Children recommended for MC approaches had significantly more myopia than those recommended single-vision lenses or monitoring (p < 0.05). Age of the first visit significantly correlated with SER change from the first visit to the next recommendation update for pre-myopes (r = 0.27, p = 0.013) but not for myopes. Conclusions: From 2017 to 2021, myopia management patterns in Hong Kong shifted significantly, with more children being recommended for myopia control. MC spectacle lenses emerged as the most commonly recommended method. Younger pre-myopes at their first visit were more likely to have earlier management updates.
