TGFB1 and wet macular degeneration: The aqueous humor concentration revealed that TGF-β2 concentrations decreased following anti-VEGF treatments, while TGF-β1 levels remained below the dose detectable and TGF-β3 concentration was unchanged, thus suggesting a role for TGF-β2 in the homeostasis of the eye under physiological conditions and under pathological conditions in wet AMD patients [189].
