• Here is some research I did for you to kick you off. To continue I would look into what mechanism the eye uses to: clear blood, protect cells, and repair damage. Look into the intracellular and extracellular routes for these mechanisms and find phytochemicals which modulate them.

• TLDR Subretinal hemorrhage (SRH) poses significant risks to vision. The retinal pigment epithelium (RPE) plays a critical role in retinal health, and its protection is vital for maintaining visual function. Phytochemicals such as curcumin and quercetin have shown promise in supporting RPE health and modulating the plasminogen system, which is crucial for fibrinolysis and the resolution of SRH.

Curcumin

• Mechanisms of Action:

1. Anti-Inflammatory Effects:

   • Curcumin inhibits nuclear factor-kappa B (NF-κB) and other inflammatory pathways, reducing inflammation in RPE cells.
   • It downregulates pro-inflammatory cytokines like TNF-α, IL-1β, and IL-6.

2. Antioxidant Properties:

   • Curcumin scavenges free radicals and enhances the activity of endogenous antioxidant enzymes (e.g., superoxide dismutase, catalase).
   • It reduces oxidative stress, which is implicated in the damage to RPE cells.

3. Fibrinolytic Activity:

   • Curcumin enhances the plasminogen-plasmin system, promoting the breakdown of fibrin clots.
   • It increases the expression of tissue plasminogen activator (tPA), facilitating fibrinolysis and potentially aiding in the resolution of SRH.

Clinical Applications:

• RPE Protection: Curcumin's anti-inflammatory and antioxidant effects protect RPE cells from damage, maintaining retinal integrity.
• SRH Management: By promoting fibrinolysis, curcumin may help in the clearance of subretinal hemorrhages, improving visual outcomes.

Quercetin

• Mechanisms of Action:

1. Anti-Inflammatory Effects:

   • Quercetin inhibits pathways like NF-κB and mitogen-activated protein kinases (MAPKs), reducing inflammation in RPE cells.
   • It decreases the production of pro-inflammatory cytokines.

2. Antioxidant Properties:

   • Quercetin directly scavenges reactive oxygen species (ROS) and upregulates antioxidant defenses.
   • It mitigates oxidative stress, protecting RPE cells from damage.

3. Fibrinolytic Influence:

   • Quercetin may modulate the plasminogen-plasmin system, though specific mechanisms in the eye require further research.
   • It has been suggested to enhance fibrinolysis, potentially aiding in the breakdown of clots.

Clinical Applications:

• RPE Protection: Quercetin's anti-inflammatory and antioxidant properties safeguard RPE cells, supporting retinal health.
• SRH Management: By influencing the plasminogen system, quercetin might assist in the resolution of subretinal hemorrhages, although more targeted research is needed.

Practical Considerations

1. Bioavailability:

   • Curcumin has low natural bioavailability; formulations with piperine (black pepper extract) or liposomal preparations can enhance absorption.
   • Quercetin also has limited bioavailability; liposomal quercetin or other advanced formulations can improve uptake.

2. Dosage:

   • Clinical trials typically use curcumin doses ranging from 500 mg to 2000 mg per day.
   • Quercetin doses in studies vary from 500 mg to 1000 mg per day.

3. Safety and Interactions:

   • Both curcumin and quercetin are generally well-tolerated, but potential interactions with medications (e.g., anticoagulants) should be considered.
   • Consult with a healthcare provider before starting supplementation, if you are on any blood thinners, as it could enhance them.
