    Will children with hypermetropia still need glasses when they grow older?

    Dear Editor,

    Bonafede et al1 analyzed the change over time in hypermetropia in children from the USA with partially and fully accommodative esotropia. This study complements a previous long-term follow-up multi-center publication on 164 hypermetropic children from USA, Germany, and Israel2. The follow-up was comparable: ages 3.5-10.5 years in the previous article compared to 3-12 years in the current paper. The range of spherical equivalent refractive error in the previous paper was categorized as +1-3Diopters (D) (mild hypermetropes) and +5-8D (high hypermetropes). In contrast, the current study included also moderate hypermetropes, because it involved a group with less than +4D hypermetropes and a group of children with hypermetropia of +4D or more. Esotropia in the previous study was not present in any of the mild hypermetropes but was present in half (48%) of the high hypermetropes. Due to a decrease in hypermetropia over time beyond the age of 6 years old, mild hypermetropes in the previous study were weaned from glasses (-0.095 D/year), while the high hypermetropes remained in glasses (-0.037 D/year). Similarly, because of a mean decrease of -0.17 D/year that occurred only from age 7 to 15 years, subjects in the current study with a “smaller baseline” (i.e., mild) hypermetropia stopped wearing glasses. However, most moderate and high hypermetropes beyond the age of 12 years remained in glasses (-0.18 D/year).

    In conclusion, data derived from both...
