Currently, no caregiver assessable scales are available, as a result, adults with ID are at high risk of delayed diagnose for common ocular conditions. Objectives: This is a one-year project. The objective of this study is two folds: 1. To develop an item bank of ocular conditions of adults with ID; 2. To develop a scale for caregivers to detect ocular conditions for adults with ID, and to validate the reliability, construct validity and responsiveness of the scale.

Inclusion Criteria: 1. Age 20 and above 2. Primary caregivers for at least one adult with ID (have disability identification or (and) certification). Exclusion Criteria: 1. Unable to communicate in Mandarin or Taiwanese.(Primarycaregivers) 2. Unable to cooperate with eye examination.(ID)
