Screening for depression in older persons with low vision. Somatic eye symptoms and the Geriatric Depression Scale.
The authors compared the sensitivity and specificity of a somatic eye symptoms question with the Geriatric Depression Scale (GDS) to detect depression in older patients with low vision. The sample was 70 patients (65+ years) attending a low-vision clinic. A geriatric nurse-practitioner examined all patients, diagnosed major depression by DSM-III-R criteria, and completed the GDS and an eye symptoms (ES) questionnaire. Twenty-seven patients (38.6%) met criteria for major depression. Although the sensitivity of the ES and GDS were identical (63%), the GDS was more specific (77% vs. 54%) and had higher positive predictive value (63% vs. 46%). Both measures identified patients who were more functionally disabled than patients without ES or depression, but with similar vision. Depression frequently accompanies visual impairment in this population. Inquiring about ES appears to be less specific than the GDS, although neither method is highly sensitive. However these screening tools identify distressed persons whose disability is high relative to the severity of their vision loss.
