Article Synopsis
- The study investigates visual impairments in individuals with albinism (PwA) compared to matched controls, focusing on the early and late stages of the visual pathway.
- Researchers used advanced psychophysical methods to measure various visual functions, such as acuity, contrast sensitivity, color detection, and motion detection in both PwA and controls.
- Results indicated PwA exhibited significant impairments across most visual functions, with distinct functional clusters identified; however, some midlevel vision aspects were comparable to controls.
Significance: Angular Indication Measurement (AIM) is an adaptive, self-administered, and generalizable orientation-judgment method designed to interrogate visual functions. We introduce AIM Visual Acuity (VA) and show its features and outcome measures. Angular Indication Measurement VA's ability to detect defocus was comparable with that of an Early Treatment of Diabetic Retinopathy Study (ETDRS) letter chart and showed greater sensitivity to astigmatic blur.
