Figure 4.

Histopathological findings in all study groups at post-op day 7. (A) Group A shows a bundle of densely packed collagen fibres interspersed between the fibroblasts, indicating a cellular response. (B) Group B, with haphazardly arranged collagen fibres with increased density of fibroblasts. (C) Group C, with predominantly loose collagen fibres (pink eosinophilic stain) with loose subconjunctival stroma. The fibroblasts are reduced in density and have fewer inflammatory infiltrates. (D) Group D shows a reduced number of fibroblasts. Dense collagen fibres are noted in the area near the lumen cannula with a cluster of inflammatory cells. Blue and black arrows indicate the labelling of the specific cells. (H&E staining, 400× magnification).
