Vision-related quality of life, metamorphopsia, and stereopsis after successful surgery for rhegmatogenous retinal detachment

Abstract

PurposeTo determine the relationship between vision-related quality of life, metamorphopsia, and stereopsis after successful surgery to correct rhegmatogenous retinal detachment (RRD).Patients and methodsData were obtained from 30 patients with RRD who had scleral buckle surgery or vitrectomy. Age, gender, duration of blurred vision, the best-corrected visual acuity (BCVA), extent of detachment, and the location of retinal tears were measured before surgery. Approximately 1 year after surgery, stereopsis was measured with the Randot stereo test, visual acuity (VA) was measured using a Snell VA acuity measurement at a distance of 5 m and was presented as a linear LogMAR value, metamorphopsia was examined using an M-chart, and vision-related quality of life was determined using the 25-Item National Eye Institute Visual Function Questionnaire (VFQ-25).ResultsAll of the patients achieved anatomical retinal reattachment. There was a significant difference between preoperative BCVA (0.78±0.72) and BCVA 1 year postoperatively (0.25±0.25) (P<0.05). Twenty-three patients had visual distortion postoperatively, including vertical metamorphopsia (0.53±0.52°), and horizontal metamorphopsia (0.48±0.53°). Twenty patients had no stereopsis. The composite score of VFQ-25 was 76.60 postoperatively. Significant differences in postoperative BCVA, metamorphopsia, and VFQ-25 were found between macula-on and macula-off groups (all P<0.05). There was a negative correlation between VFQ-25 composite score and metamorphopsia (P<0.005); there was no significant correlation between VFQ-25 composite score and BCVA or stereopsis.ConclusionVision-related quality of life correlated with metamorphopsia, but did not correlate with VA or stereopsis.
