Abstract Details

Purpose:

To report the scores of a Portuguese translated version of the Quality of Vision (QoV) questionnaire in a sample of subjects attending an ophthalmic examination.

Setting:

CEORLab - Center of Physics, University of Minho, Braga, Portugal

Methods:

The QoV questionnaire was translated into Portuguese and the translated version was reviewed by a linguistic specialist. One hundred and ninety-eight consecutive subjects underwent a comprehensive ophthalmic examination including history taking and refractive error determination, contrast sensitivity followed by the application of the QoV questionnaire. QoV scores were calculated for the three subscales of the questionnaire were calculated and the distribution of individual symptoms were evaluated.

Results:

Median QoV scores were 38.5 for frequency (95%CI: 36.9 to 42.4; interquartile range: 27), 32.0 for severity (95%CI: 30.4 to 35.0; interquartile range: 22) and 34.0 for bothersome (95%CI: 32.5 to 38.0; interquartile range: 27). No significant correlation was observed between each of the subscores (Rho <0.100; p>0.05). Frequency, severity and bothersome sub-scales were significantly correlated with high (Rho=0.332, 0.307, 0.409, respectively) and low contrast (Rho≥0.235, 0.277 and 0.306, respectively) visual acuity (p≤0.040).

Conclusions:

QoV scores were higher (worse) in this cohort of patients attending for routine eye examination compared to previous reports following surgical interventions including laser refractive surgery and cataract surgery. The results act as a reference range for future comparisons. There was no correlation between QoV scores and refractive error, visual acuity and contrast sensitivity.
