Figure 10. Choroidal vascular casts. Frontal view of choroidal casts showed that 30 days after injection of triamcinolone acetonide (TA), the avascular areas were increased (B, red double-headed arrow) as compared to the control PBS-treated eyes (A). Cross-sectional cuts of pericentral choroidal corrosion cast (C, D) showed a reduced thickness of the choriocapillaries in TA-treated eyes. Scale bar represents 10 µm. E: Quantification of the avascular areas in the choriocapillaries confirmed a significant increase in TA-treated eyes, and (F) mean vessel diameter was significantly reduced. Results are expressed as mean±standard error with *p<0.05 when consideringTA versus PBS. Six animals were used in this study.
