Brief summary
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.
Detailed description
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.
Interventions
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The best-corrected visual acuity (BCVA) | 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 | 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. |
| M-charts | 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. |
| Central retinal thickness | 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 | 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. |
