Kadhum A, Simonsz‐Tóth B, van Rosmalen J, et al. - In the present study, the researchers sought to determine the change in visual acuity (VA) in the population of a previous amblyopia treatment study (Loudon 2006) and evaluate risk factors for VA decrease. Regression analysis was performed to determine the impact of clinical and socioeconomic factors on changes in InterOcular VA Difference. Of the 303 participants from the original study, 208 were successfully approached, 59 were denied, and 15 were omitted due to non-amblyopic causes of visual impairment. According to the findings, long‐term outcomes of occlusion therapy were good. Long‐term VA decrease was associated with high or increasing anisometropia, eccentric fixation, and non‐compliance during occlusion therapy. Despite little patching, patients with poor initial VA had a larger increase but also showed long‐term VA decrease.
