A family comprises two daughters and a son, were diagnosed with Peters' anomaly. Assessment included: visual and reading acuity, visual field, contrast sensitivity, and color vision. Different devices were employed based on each individual's visual needs and capabilities.

The second daughter had 6/60 visual acuity in both eyes, a restricted visual field, moderate contrast sensitivity, and abnormal color vision. Both girls were given a +12.00D binocular spectacle for near, and a telescope for distance, additionally, they were recommended to utilize a typoscope, felt pen, and reading stand for near tasks. The son had 6/75 vision at distance and near in both eyes, a restricted visual field, significantly reduced contrast sensitivity, and normal color vision. The son does not attend school; instead, he has been instructed in the use of a mobile phone application designed to magnify small print, and an 8x monocular telescope for distant viewing. He was also referred to a local organization that provides vocational training for young with disabilities.
