A review of patient-reported outcome measures used in uveitis

We review patient-reported outcome measures (PROMs) used to evaluate the quality of life (QoL) in uveitis and provide a quality assessment of the psychometric properties of the PROMs, making it easier to choose the best questionnaire for uveitis. Our review included 158 articles. A total of 98 PROMs were used to measure QoL in uveitis and the National Eye Institute Visual Function Questionnaire 25 (NEI VFQ -25) was the most frequently used PROM in these studies. There were 5 uveitis-specific PROMs, but they were meant for either birdshot choroidopathy or cytomegalovirus retinitis or paediatric uveitis. There are no PROMs developed explicitly for the more common, anterior uveitis, intermediate uveitis, panuveitis, and chronic uveitis. The uveitis-specific PROMs performed better in our quality assessment criteria compared to other PROMs. However, these PROMs were constructed using traditional classical test theory and have not been assessed using the modern family of psychometric assessment methods such as Rasch analysis. As new therapeutic modalities for uveitis such as the new biological agents and steroid implants, continue to evolve, a comprehensive PROM will be increasingly valued in clinical trial settings to compare the effects of treatments from the patient's perspective.
