Characterization of Bangerter filter effect in mild and moderate anisometropic amblyopia: predictive factors for the visual outcome

Abstract

Bangerter filters are useful for treating mild or moderate amblyopia due to anisometropia, but ocular dominance inversion should be maintained during treatment for obtaining an optimized outcome.

Optical treatment of amblyopia: a systematic review and meta‐analysis

“…Twenty papers are included in the meta‐analysis. Fourteen of the papers included the data necessary to be able to calculate an ES, with four of those requiring data extraction from graphs using WebPlotDigitiser . Sixteen authors responded to our requests for information, with three of them providing data and one providing clarification about the study.…”

“…Data from a further five papers were made available through personal communication (C Birch in emails to L Asper, 14 and 19 April 2017; Xi Yu in an email to L Asper, 9 April 2017; and Raymond Kraker, Director, PEDIG Coordinating Center, in emails addressed to L Asper, 10 April 2017 and 31 May 2017). Table summarises the 20 papers in the meta‐analysis that investigated a total of 1,346 amblyopic eyes …”

The Effect of Bangerter Filters on Binocular Function in Observers With Amblyopia

“…One technique for partial occlusion is to adhere a Bangerter filter to the spectacle lens in front of the nonamblyopic eye. 30,31 These filters are made up of microelements that produce localized image distortions. The distortions reduce optotype acuity, vernier acuity, and contrast sensitivity to mid-high spatial frequencies in the filtered eye.…”
