Randomized Controlled Trial Multicenter Study Comparative Study
Visual Acuity and Over-refraction in Myopic Children Fitted with Soft Multifocal Contact Lenses.
Practitioners fitting contact lenses for myopia control frequently question whether a myopic child can achieve good vision with a high-add multifocal. We demonstrate that visual acuity is not different than spectacles with a commercially available, center-distance soft multifocal contact lens (MFCL) (Biofinity Multifocal "D"; +2.50 D add). ⋯ Children achieved BCVA with +2.50 D add MFCLs that was not different than with spectacles. Children typically required an over-refraction of -0.50 to -0.75 D to achieve BCVA. With a careful over-refraction, these +2.50 D add MFCLs provide good distance acuity, making them viable candidates for myopia control.

Communication Predicts Medication Self-Efficacy in Glaucoma Patients.
Medication self-efficacy, or patients' confidence that they can perform medication-related behaviors, is associated with better glaucoma medication adherence. Little is known about how to enhance glaucoma patients' medication self-efficacy. Our purpose is to examine whether patient-provider communication increases glaucoma patients' medication self-efficacy. ⋯ When providers educate glaucoma patients and assess patient views about glaucoma and its treatment, patients report higher medication self-efficacy. Providers should be aware that patients who ask more medication questions may have less confidence in their ability to overcome barriers to adherence.

Poor stereoacuity among children with poor literacy: prevalence and associated factors.
Population-based studies on abnormal binocular vision and low literacy are rare. The aim is to determine the prevalence of poor stereoacuity among children with low literacy; to identify the characteristics associated with poor stereoacuity among children with low literacy; and to determine the agreement between poor stereoacuity as measured by graded stereocircles with a computerized assessment. ⋯ In this low-literacy sample, one-sixth had low stereoacuity. The associations reported require further investigation.
