The association of cataract and depression score was not solely driven by ageCataract was also associated with lower cognitive function in unadjusted analysis at baseline and at follow-up two years later, but this association was removed after adjustment for covariates. “Pseudophakic, versus phakic, status of study participants did not show strong evidence of association with depression, or cognitive function. Unfortunately, we could not determine an effect of cataract surgery, as we did not follow depression score in participants before and after surgery. This could be an area for further research,” said Dr Quigley. "Interestingly, we found that the association of cataract and depression score was not solely driven by age, there are other factors underlying the association, vision-related quality of life may be an important," The fact that the presence of cataract was lower than previous studies may be due to self-reported nature of the data, said Dr Quigley. “The strengths of the study were a large sample, and that multiple variables were assessed, while the weaknesses were the likely underestimation of cataract incidence, and the lack of visual acuity data or slit lamp examination,” she said.
