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.
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.

Microperimetry is a procedure to assess retinal sensitivity while fundus is directly examined; it enables exact correlation between macular pathology and corresponding functional abnormality.
The M-chart (Inami Co., Tokyo, Japan) is a diagnostic tool developed by Matsumoto to quantify the degree of metamorphopsia in patients with macular diseases.

The best-corrected visual acuity (BCVA)
Acuity is a measure of visual performance. The eye exam seeks to find the prescription that will provide the best corrected visual performance achievable.
Time frame: 1 to 6 months
Amsler test
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.
Time frame: 1 to 6 months
M-charts
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.
Time frame: 1 to 6 months
Central retinal thickness
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.
Time frame: 1 to 6 months
Microperimetry
Microperimetry is a procedure to assess retinal sensitivity while fundus is directly examined; it enables exact correlation between macular pathology and corresponding functional abnormality.
Time frame: 1 to 6 months
