Abstract

Purpose: To investigate vision-related quality of life (VR-QOL) in patients undergoing vitrectomy for various vitreoretinal disorders and to evaluate the relationship between VR-QOL and visual function.

Methods: We studied 100 normal controls and 299 patients with various vitreoretinal disorders including proliferative diabetic retinopathy (PDR), diabetic macular edema (DME), branch retinal vein occlusion (BRVO), central retinal vein occlusion (CRVO), macular hole (MH), epiretinal membrane (ERM), and rhegmatogenous retinal detachment (RD). The 25-item National Eye Institute Visual Function Questionnaire (VFQ-25) was answered by the patients with vitreoretinal disorders before and 3 months after pars plana vitrectomy, as well as by the normal controls. Clinical data were collected, including visual acuity, contrast sensitivity, and severity of metamorphopsia.

Results: Vitrectomy significantly improved VFQ-25 composite score in all vitreoretinal disorders. Preoperative VFQ-25 composite scores in MH and ERM were significantly higher than those in PDR, DME and BRVO. Postoperative VFQ-25 composite scores were significantly higher in MH, ERM and RD than in PDR, DME, BRVO and CRVO. Greater improvement in VFQ-25 composite score was observed in ERM than in DME. Multiple regression analysis revealed that changes in contrast sensitivity had a significant correlation with changes in VFQ-25 composite score in PDR and DME. Changes in metamorphopsia were significantly associated with changes in VFQ-25 composite score in MH and ERM.

Conclusions: Vitrectomy significantly improved VR-QOL in various vitreoretinal disorders. The largest improvement in VR-QOL was observed in ERM and smallest improvement in DME. The visual function parameters associated with VR-QOL are different depending on vitreoretinal disorders.

Key Words: vitreoretinal surgery • quality of life • visual function
