The three most common ocular abnormalities were follicular conjunctivitis (55.8%, 153\/274 eyes), cataracts (27.4%, 75\/274 eyes), and multifocal chorioretinopathy (\u201cbullet holes\u201d; 19%, 52\/274 eyes). The prevalence for ERU among Icelandic horses aged \u201ceight years and older\u201d was 8% (6\/75\u00a0horses). The \u201cinsidious ERU\u201d type was found in 83% of the ERU cohort (5\/6\u00a0horses), while \u201cclassic ERU\u201d was found in 17% (1\/6\u00a0horses).
