Resumen
Fecha de inicio: 1 de junio de 1996
Fecha en la que se inscribió al primer participante.Roughly a quarter of people in the United States have myopia, or nearsightedness, which commonly begins in childhood and progresses rapidly until around age 16. This condition can increase the risk of retinal detachment due to excessive eye growth. Previous studies have shown mixed results about the effectiveness of bifocals in slowing myopia progression. However, there is some evidence to suggest that bifocals may be beneficial for children with near-point esophoria, a condition where the eyes tend to turn inward when focusing on close objects. This study aims to further investigate the potential benefits of bifocals for myopic children with near-point esophoria. Over 80 children with this condition will be randomly assigned to wear either single-vision glasses or bifocals with a +1.50 D add. Participants will visit one of two sites every 6 months for 30 months, for a total of six visits. During these visits, measurements will be taken to assess changes in myopia and eye growth. Questionnaires will also be administered to gather information about the amount of close work, such as reading or using electronic devices, that the participants engage in.

Criterios
Boys must have been between 6 and 12 years of age; girls between 6 and 11 years of age. All children must have had at least 0.5 diopters of myopia in both eyes, near-point esophoria, at least 20/25 acuity in each eye, and 40 seconds of stereopsis and must have been free of ocular disease or systemic disease that may have altered refraction. All subjects were willing to wear bifocal spectacle lenses for 30 months.
