Diabetic Retinopathy: Science vs. Alternative
Between the waiting room of eye clinics and the corridors of social media, an incessant debate rages between a patient clinging to the hope of natural healing and a doctor racing against time to preserve what remains of their patient's vision.
In recent years, the “Al-Tayebat System” proposed by Dr. Diaa Al-Awadi has sparked widespread controversy, dividing the medical community between proponents and opponents. Parallel to this, traditional practices such as medicinal leech therapy and herbal remedies have also gained traction. In this comprehensive awareness article, we will place the claims of this system and alternative medicine practices under the scrutiny of impartial scientific research: what are its merits, what are its drawbacks, and when does theoretical debate turn into a danger that threatens the safety of your eyes?
The Claims of the “Al-Tayebat System” Verbatim: A Scientific Review and Critique
To be fair to the claims, we must review the basic principles advocated by Dr. Diaa Al-Awadi and analyze them against the scale of evidence-based medicine:
First Claim: “Diabetes is not a chronic disease; it is merely a symptom of food poisoning and intestinal irritation, and eliminating triggers completely cures the disease.”
Scientific Analysis:
Positives: Eliminating hydrogenated oils, processed foods, and white sugar is something all doctors worldwide agree on. Reducing inflammatory triggers in nutrition significantly reduces insulin resistance and helps noticeably lower HbA1c.
Negatives: Reducing diabetes (especially type 2) to mere “food poisoning” is an oversimplified explanation for a complex disease involving genetic factors, pancreatic function, and hormonal imbalances. Dietary control manages the disease but does not “erase” genetic predisposition and the damage already done to blood vessels.
Second Claim: “Al-Tayebat specific prohibitions and allowances (prohibiting leafy green vegetables and legumes, and relying on specific foods such as rice, tea, coffee, and figs).”
Scientific Analysis:
Positives: Focusing on easily digestible foods may alleviate irritable bowel syndrome symptoms in some patients.
Negatives: Banning leafy green vegetables and legumes deprives diabetic patients of potent antioxidants (such as lutein and zeaxanthin), which are vital elements for protecting retinal cells from oxidative stress. This strict prohibition lacks scientific support and is not documented by any accredited clinical study.
Third Claim: “If blood sugar is controlled through diet, all body organs will automatically recover, and complications, including those in the eye, will recede.”
Scientific Analysis:
This is the pivotal and most dangerous point in the debate. Blood sugar control prevents the occurrence of “new” damage, but it cannot “turn back time” regarding existing damage. If the retinal blood circulation has been blocked, or if blood vessels have leaked and macular edema (DME) has occurred, blood sugar control alone cannot seal the existing leak, absorb trapped bleeding inside the eye, dissolve retinal fibrosis, or reattach a detached retina.
Medicinal Leech Therapy: Does it Absorb “Bad Blood” from the Retina?
Among the practices frequently discussed in alternative medicine circles for treating eye problems is the use of medicinal leech therapy, which is promoted as secreting “hirudin” (a blood thinner) and extracting toxins from the area around the eye.
The Scientific Debate on Leech Therapy:
Traditional Concept: Based on an old idea that drawing blood from the skin around the eye relieves pressure and stimulates sluggish blood circulation within the retina.
Medical and Anatomical Reality:
Blood-Retinal Barrier: The eye is a closed organ protected by very delicate barriers. Applying leeches to the outer skin or cheek has no physiological mechanism that allows it to “extract” fluids or bleeding present within the vitreous humor or under the retina.
Risks of Severe Bacterial Infection: The living leech contains bacteria called Aeromonas hydrophila in its digestive system. Placing this organism near the eye carries high bacterial risks that can lead to periorbital cellulitis or even panophthalmitis, a nightmare that can cause total vision loss.
Risk of Coagulopathy and Bleeding: The blood-thinning substance secreted by the leech may worsen the situation and increase the risk of fresh bleeding within the vitreous humor for a diabetic patient.
Retinal Conflict: Why Does Tissue Damage Precede Nutrition?
In the context of discussing the ocular complications of diabetes, it is crucial to highlight one of the most serious of these complications: diabetic vitreous hemorrhage, which can lead to vision loss if not managed correctly and promptly.
Since diabetes affects many parts of the eye, understanding all potential complications is essential. Diabetic macular edema is one of the most serious of these complications, causing severe vision deterioration and requiring urgent medical intervention.
To understand why direct medical treatment cannot be replaced, let's look at what happens inside the eye as a mechanical conflict:
Leakage and Swelling: Diseased capillaries in the macula become like a "clogged and punctured water pipe," leaking fluid into the macula. No matter how excellent the diet, it cannot seal these microscopic holes.
Oxygen Deprivation and Abnormal Vessel Growth: When the retina is deprived of oxygen, it releases a protein called (VEGF). This protein creates haphazard blood vessels like "brittle straw," which immediately rupture and fill the eye with blood, or turn into scar tissue that pulls on the retina, causing severe retinal detachment.
Medical treatment here does not fight nutrition; rather, it immediately intervenes in this mechanical conflict to stop it.
Therapeutic Confrontation: International Guidelines (ADA) and Modern Medicine
With the progression of diabetic retinopathy, advanced interventions may be required to preserve or restore vision. To learn about one of the most important of these treatments, you can read more about intravitreal injections used to treat various retinal diseases.

While doctors agree on the importance of blood sugar control to prevent complications, ocular changes may require precise medical intervention. In some advanced cases, surgical intervention may be necessary to preserve vision, as in diabetic vitreous hemorrhage which may necessitate surgical vitrectomy.

The American Diabetes Association (ADA) and global retinal surgery societies do not ignore nutrition, but they set a firm roadmap:
First Line of Rescue - Intravitreal Injections (Anti-VEGF): Directly targeting the (VEGF) protein with very precise injections into the eye to stop leakage and promote reabsorption.
Retinal Laser (Argon Laser): Cauterizing atrophic areas to stop the secretion of hemorrhage-inducing substances and protect the retinal periphery.
Advanced Surgery (Vitrectomy): Surgical removal of the vitreous, blood, and tractional scar tissue through delicate procedures.
The integration of these options with a healthy, balanced diet is the only formula proven by data and studies to protect patient vision.
Conclusion: Not Conflict, But Wisdom in Decision-Making
We do not attack the desire for healthy nutrition, nor do we deny that reducing oils and sugars is an excellent lifestyle. However, the fatal risk is replacing proven medical intervention with illusions.
Always remember: nutrition controls blood sugar to prevent future damage, while injections, laser, and surgery treat existing damage. Preserving your eyes requires combining both wisely and without delay.
