Study demonstrates the impact of fogging lens on refractive status in young patients, suggesting the need for careful screening protocols.
This study addressed the question: “Should both eyes be fogged during static retinoscopy?” Static retinoscopy measures were taken on young patients. (N=50; mean age=9 years, 4 months). Outcomes revealed no differences except with hyperopic patients, where the lack of a fogging lens over the partner eye resulted in a significant underestimate (p <.001) of the refractive status. This argues against the use of a lens bar for retinoscopy especially in vision screening programs involving young children.
