CVSS

Also written as: CVSS — Cortical Visual Impairment Severity Scale

Cortical Visual Impairment Severity Scale, a standardized assessment tool for cortical vision dysfunction in children.

Full Definition

The Cortical Visual Impairment Severity Scale (CVSS) is a validated clinical instrument used to assess the severity and characteristics of cortical visual impairment in pediatric patients. The scale evaluates multiple domains including visual attention, visual field defects, visual crowding, and behavioral responses to visual stimuli. CVSS provides a systematic approach to documenting cortical vision dysfunction and tracking changes over time. It is particularly valuable in children with neurological conditions affecting the visual cortex, helping clinicians distinguish cortical visual impairment from ocular causes of vision loss.

Usage

Usage note: Always spell out on first use; distinguish from general CVI terminology.
