Abstract

Purpose: To determine vision-related quality of life (VR-QoL) and functional and structural parameters associated with VR-QoL in patients with glaucoma before and 12 months after trabeculectomy. 

Methods: Fifty-eight patients undergoing trabeculectomy were included. Participants completed the 25-item National Eye Institute Visual Function Questionnaire (VFQ-25) prior to and 12 months after trabeculectomy. Functional (visual acuity and visual fields) and structural (ganglion cell layer volume) parameters were evaluated for their association with VR-QoL using multiple linear regression of VFQ-25 subscale scores. Intraocular pressure and the number of glaucoma medications were also included in the analyses.

 Results: The VFQ-25 composite score did not change after trabeculectomy (before: 74.9; 12 months: 74.0; p = 0.512). The subscale mental health had a significantly higher score 12 months after trabeculectomy (before: 65.6; 12 months: 71.4; p = 0.017). The VFQ-25 scores for general health (before: 68.5; 12 months: 62.5; p = 0.009) and role difficulties (before: 78.9; 12 months: 53.7; p < 0.001) were significantly lower 12 months after trabeculectomy. No functional or structural parameters were associated with VFQ-25 composite score. 

Conclusion: Overall, VR-QoL in glaucoma patients was similar before and after trabeculectomy, reflecting the procedure's stabilizing effect on both objective and subjective visual function. The absence of correlations between VR-QoL and clinical parameters emphasizes the multifaceted nature of VR-QoL and highlights the limitations of depending solely on objective clinical metrics to evaluate patients' subjective experiences. Using both objective measures and VR-QoL, clinicians can better understand the challenges patients face due to glaucoma and trabeculectomy, potentially leading to better solutions.
