To evaluate the vision-related quality of life and visual function following vitrectomy for macular hole (MH) using the 25-item National Eye Institute Visual Function Questionnaire (VFQ-25).
The VFQ-25 was self-administered by 23 patients with MH (age 66.3 ± 5.0 years, mean ± SD) preoperatively and at 3 months postoperatively. Clinical data were collected including logMAR best corrected visual acuity (BCVA), letter contrast sensitivity and the severity of metamorphopsia. Letter contrast sensitivity was evaluated by CSV-1000LV (Vector Vision Co.), and metamorphopsia was evaluated by M-CHARTS (Inami Co.). The preoperatively macular hole index (MHI) was calculated using optical coherence tomography (Stratus OCT 3000, Carl Zeiss Co.).
The preoperative VFQ-25 composite score significantly correlated with the preoperative logMAR BCVA (p < 0.05). The VFQ-25 composite score and the subscales associated with general vision, near activities, social functioning, mental health, role difficulties, and dependency were significantly improved by surgery (p < 0.05). Changes in the VFQ-25 composite score significantly correlated with changes in the severity of metamorphopsia (p<0.01). The MHI significantly correlated with preoperative severity (p<0.05) and the improvement (p<0.05) of metamorphopsia.
MH surgery improved VFQ-25 composite score, and improvement of the VFQ-25 composite score was significantly associated with improvement of metamorphopsia. Metamorphopsia plays an important role for the vision-related quality of life of patients with MH.
