A practical remedy, which we call artificial perturbation, is to treat grid nodes very near the boundary as boundary points.
The two eyes which exhibited retinal ischemia in less than two quadrants and macular oedema were treated with grid laser and focal laser on the macroaneurysms, but did not undergo PRP.
Among the three eyes with macular oedema that were treated with grid laser (cases 1, 7, 8), the mean central foveal thickness (CFT) measured by optical coherence tomography (OCT) at initial visit was 276 μm (range, 267 to 285 μm) and at final visit was 224 μm (range, 218 to 228 μm) (Table 2).
For example, the randomized controlled branch vein occlusion study (BVOS) revealed that patients treated with grid photocoagulation showed a greater visual improvement than did untreated patients [ 2].
The simple fact that only 11 of the 738 patients with RVO had their edema treated with grid laser photocoagulation monotherapy shows a major shift in treatment philosophy of RVO.
Alternatively, hazardous samples may be inactivated after they are mounted on the grid by treating the grid with fixative, by subjecting stained preparations to ultraviolet irradiation (UV) for 5 min before removing them from the biological safety cabinet, or both.
This method treats a grid cell in D2T as dry if it was touching a dry grid cell in D1.
The collected data were coded in MS Excel grids, treated in an aggregate manner and processed with the aid of SPSS statistical software version 20.0 for Windows 2010.
Controls consisted of specimens on grids treated in the same manner, except that primary antibodies were omitted.
Samples were placed on 100-mesh formvar-coated copper grids treated with poly- L-lysine for 1 h.
