Cognitive biases, systematic errors in thinking that impact a person's choices and judgments, can influence decision making at various points during patient care provision. These biases can potentially result in misdiagnoses, delayed clinical care, and/or patient mismanagement. A range of interventions exists to mitigate cognitive biases. There is a need to understand the relative efficacy of these interventions within the context of eye care practice. ⋯ Given that cognitive biases can significantly impact the accuracy of clinical decision making and thus can have major effects on clinical care and patient health outcomes, the lack of studies identified in this systematic review indicates a critical need for research within the area of cognitive bias mitigation for decision making within eye care practice.

This first report of the use of objective measures of disparity vergence as outcome measures for symptomatic convergence insufficiency in children provides additional information that is not accessible with clinical tests. The study results also demonstrate that objective measures of vergence could be used in future randomized clinical trials of binocular vision disorders with children. ⋯ In this prospective study on the treatment of symptomatic convergence insufficiency in children in which both clinical and objective eye movement measurements were used to evaluate the results of treatment, significant changes were found in symptoms and both clinical and objective measures of disparity vergence after completion of OBVAT in children with symptomatic convergence insufficiency.

Comparative Study
Ranibizumab versus Dexamethasone Implant in Macular Edema Secondary to Branch Retinal Vein Occlusion: Two-year Outcomes.
We compared the 24-month outcomes of ranibizumab and dexamethasone implants in treatment-naive branch retinal vein occlusion patients. Ranibizumab was effective in improving visual outcomes, whereas the dexamethasone implant was not. ⋯ Ranibizumab was effective in the treatment of macular edema secondary to branch retinal vein occlusion in both visual and anatomical outcomes; however, dexamethasone implant was effective only in anatomical outcomes.

The response of the pupil to a flash of light, the pupillary light reflex (PLR), is an important measure in optometry and in other fields of medicine that is typically evaluated by qualitative observation. Here we describe a simple, portable, iPhone-based pupillometer that quantifies the PLR in real time. ⋯ There is excellent agreement between pupil responses recorded using the Sensitometer test and IR camera. The Sensitometer test provides a highly promising approach for simple, portable, inexpensive pupillary measurements.

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.
