Purpose
To investigate the relationship between visual acuity and central visual field on vision related quality of life (VRQOL) in advanced glaucomatous patients.
Methods
We conducted hearing investigation using the ‘Sumi questionnaire’ (Sumi et al. Opthalmol. 2003;110:332-339) on 50 advanced glaucomatous patients who had mean deviation(MD) less than -15dB (Humphrey 24-2 SITA Standard program) at least in one eye. VRQOL score in each task (Word/Walk/Move/Eat) was calculated as the sum of scores of all questions of the task,we have calculated total and itemized. Visual field (VF) was measured using Humphrey SITA Standard propram(10-2). The impact of MD of better eye (MD-bet), MD of worse eye (MD-wor), VA(LogMAR VA) of better eye (VA-bet) and VA of worse eye (VA-wor) were compared using the correlation coefficients. Furthermore, partial regression was used to estimate the direct impact of a variable, in relationship with another variable.
Results
The correlation coefficient of each VRQOL score (Total/Word/Walk/Move/Eat) was (-0.39/-0.42/-0.37/-0.34/-0.17(MD-bet)), (-0.24/-0.27/-0.35/-0.12/-0.11(MD-wor)), (0.57/0.40/0.37/0.21/0.17(VA-bet)), (0.34/0.28/0.37/0.11/0.02(VA-wor)), respectively. In the comparison between better and worse eyes, the partial correlation coefficient of each VRQOL score (Total/Word/Walk/Move/Eat) was (-0.34/-0.25/-0.32/-0.13/-0.32(MD-bet)), (-0.08/-0.21/0.05/-0.03/-0.07(MD-wor)), (0.32/0.25/0.18/0.18/0.50(VA-bet)), (0.12/0.24/0.01/-0.07/0.11(VA-wor)), respectively. In the comparison between MD-bet and VA-bet, the partial correlation coefficient of each VRQOL score (Total/Word/Walk/Move/Eat) was (-0.36/-0.31/-0.30/-0.13/-0.31(MD-bet)) and (0.34/0.31/0.14/0.13/0.53(VA-bet)),respectively.
Conclusions
The result of partial correlation analysis revealed the direct effect of worse eye on VRQOL was smaller than that of better eye, except for the task of Word. Both of MD-bet and VA-bet are closely related to VRQOL scores.
