Vision‐related quality of life in patients with glaucoma before and after trabeculectomy.

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.
