简要总结
To examine morphological and functional results after pars plana vitrectomy (PPV) with SF6 gas tamponade due to macula-on and macula-off rhegmatogenous retinal detachment (RRD) during six months of the follow-up.
详细描述
Background:
To examine morphological and functional results after pars plana vitrectomy (PPV) with SF6 gas tamponade due to macula-on and macula-off rhegmatogenous retinal detachment (RRD) during six months of the follow-up.
Methods:
The study included 62 eyes that underwent successful PPV with SF6 tamponade with macula-on (34 eyes) and macula-off (28 eyes) RRD preoperatively. The best-corrected visual acuity (BCVA), Amsler test, M-charts, optical coherence tomography (OCT) and microperimetry were performed at 1, 3 and 6 months postoperatively.

结局指标
主要结局
M-charts
时间窗: 1 to 6 months
The M-charts consist of 19 dashed lines with increasing distance between points in the range of 0.2 ° to 2.0 ° viewing angle. Matsumoto developed M-charts for quantitative metamorphopsia evaluation in macula diseases in 1990. M-charts provide more information than Amsler chart in regard to the horizontal and vertical lines.
The best-corrected visual acuity (BCVA)
时间窗: 1 to 6 months
Acuity is a measure of visual performance. The eye exam seeks to find the prescription that will provide the best corrected visual performance achievable.
Amsler test
时间窗: 1 to 6 months
The standard Amsler test performs with black lines on the white background. The Amsler grid has been used so far for the qualitative assessment of the metamorphopsia since 1947.
Central retinal thickness
时间窗: 1 to 6 months
Quantitative thickness measurements derived from the "fast macular scan" algorithm report retinal thickness at several locations including the center point, central subfield, and 4 inner and 4 outer zones of the macula.
Microperimetry
时间窗: 1 to 6 months
Microperimetry is a procedure to assess retinal sensitivity while fundus is directly examined; it enables exact correlation between macular pathology and corresponding functional abnormality.
