Diabetic Retinopathy
消渴内障 · xiāo kě nèi zhàngDiabetic retinopathy in TCM is understood as a progression through distinct patterns - Yin deficiency, Qi and Yin depletion, and blood stasis - and treatment shifts with each stage. Early, consistent care can help stabilize the retinal vessels and reduce the frequency of invasive procedures.

Diabetic retinopathy is a complication of diabetes that damages the light-sensitive tissue at the back of the eye. Over time, elevated blood sugar weakens and blocks the tiny blood vessels that nourish the retina, causing them to leak fluid or bleed. In later stages, the eye tries to grow new vessels, but these are fragile and can lead to severe vision loss.
Symptoms often develop gradually - blurred vision, dark floaters, difficulty seeing at night, and eventually blank spots. An ophthalmologist diagnoses it through a dilated eye exam and imaging that reveals hemorrhages, exudates, and abnormal vessel growth. The condition is staged from mild non-proliferative changes to advanced proliferative disease with a high risk of blindness.
Conventional treatments
Standard care focuses first on tight blood sugar, blood pressure, and cholesterol control to slow progression. When the disease advances, treatments include laser photocoagulation to seal leaking vessels, injections of anti-VEGF drugs into the eye to block abnormal vessel growth, and in severe cases, vitrectomy surgery to remove blood or scar tissue. These interventions can preserve vision but do not reverse existing damage or address the underlying susceptibility that allowed the condition to develop.
Where conventional treatment falls short
Conventional treatments are remarkably effective at preventing severe vision loss in advanced stages, but they are reactive - they intervene after significant damage has already occurred. They do not actively rebuild the fragile retinal vessels or correct the internal environment that makes them leak and bleed.
Many patients feel caught between monitoring and invasive procedures, with few options to actively support their eye health in the earlier stages. TCM steps into this gap by aiming to nourish and stabilize the retina's blood vessels from within, potentially slowing progression and complementing the high-tech interventions when they become necessary.
How TCM understands diabetic retinopathy
TCM views diabetic retinopathy not as an isolated eye problem but as a late-stage consequence of Xiao Ke, the broader wasting-and-thirsting disorder that corresponds to diabetes. The root lies in years of high blood sugar consuming the body's Yin - the cooling, moistening, nourishing foundation - especially in the Kidneys and Liver. When Yin is too weak to anchor the body's Yang, empty heat rises along the channels to the eyes, where it scorches the delicate retinal vessels, making them brittle and prone to leakage.
This is why early signs often include dry eyes, mild redness, and tiny dot hemorrhages.
As the condition deepens, the Spleen's ability to produce Qi from food also falters, leading to a dual depletion of Qi and Yin. The energy that should hold blood within the vessels grows too weak, while the nourishing fluids that keep vessels supple run dry - a combination that produces cotton-wool spots, more widespread bleeding, and fatigue.
At any stage, sluggish blood flow can congeal into Blood Stagnation, a pattern of sticky, congealed circulation that blocks nourishment to the retina and fuels the growth of fragile new vessels. This is why hard exudates, large hemorrhages, and abnormal vessel growth are seen as blood stasis complicating the underlying deficiency.
In advanced disease, the body's reserves are so drained that even the warming Yang of the Kidneys becomes depleted. The retina then suffers from a lack of both nourishment and warmth, leading to severe ischemia and a pale, puffy tongue with cracks - a sign of deep exhaustion.
TCM's strength is that it sees this progression not as one monolithic disease but as a sequence of shifting patterns, each needing a different treatment focus: nourishing Yin early, then supplementing Qi and moving blood, and later warming and restoring both Yin and Yang.
「其病变多发痈疽，或为目疾，至甚则盲。」
"When the disease lingers, it often produces abscesses and deep-rooted sores, or becomes an eye disorder, and in severe cases leads to blindness."
How a TCM practitioner diagnoses diabetic retinopathy
Inside the consultation
A practitioner starts by looking for the root pattern of Empty-Heat or Fire caused by Yin Deficiency, which typically appears in the early background stage. You might notice dry, slightly red eyes, occasional blurring, or tiny floaters. The tongue is red with a thin or absent coat, and the pulse feels thin and rapid, confirming that Yin is too weak to anchor the body’s warming function.
As the condition moves toward the preproliferative stage, Qi and Yin Deficiency becomes more prominent. You may feel unusually tired and short of breath, and your vision might decline more noticeably, sometimes with dark spots. The tongue appears pale and puffy with tooth marks, and the pulse is thin and forceless, showing that both vital energy and nourishing fluids are depleted.
Blood Stagnation is a key complication that can develop at any stage, but becomes more obvious when there are visible retinal hemorrhages, hard yellowish exudates, or abnormal new vessel growth. The tongue often turns dark purple or shows stasis spots, and the pulse may feel choppy and uneven. This pattern rarely stands alone - it usually overlays one of the underlying deficiency states.
In the advanced proliferative stage, long-standing Yin damage eventually weakens Yang, leading to a combined Kidney Yin and Yang Deficiency. This pattern is associated with severe ischemia, neovascular glaucoma, and a high risk of vitreous hemorrhage. You may feel cold, experience frequent night-time urination, and notice swelling. The tongue is pale and puffy, and the pulse is deep, slow, and weak.
TCM Patterns for Diabetic Retinopathy
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same diabetic retinopathy can come from several different patterns, each treated differently. The quickest way to find yours is the quiz below.

Which signs match your experience?
It is very common to see yourself in more than one pattern, because Blood Stagnation often accompanies any of the deficiency states. For example, you might have the fatigue and pale tongue of Qi and Yin Deficiency while also noticing retinal bleeding that points to Blood Stagnation. This overlap is normal and reflects the way diabetic retinopathy progresses over time.
To narrow things down, focus on what feels most dominant right now. If dryness, heat sensations, and thirst are strongest, the Yin Deficiency with Empty-Heat pattern is likely primary. If overwhelming tiredness and breathlessness stand out, Qi and Yin Deficiency may be the bigger piece. When you notice new bleeding or dark spots, Blood Stagnation is actively driving the picture.
Because diabetic retinopathy can lead to permanent vision loss, a professional eye exam and a TCM tongue-and-pulse diagnosis are essential. An ophthalmologist can stage the retinal changes, while a TCM practitioner can identify the precise pattern and tailor herbs or acupuncture to support your eyes and overall health. Self-treatment is not recommended.
If you experience any sudden vision change, a shower of new floaters, or eye pain, see a professional immediately. These can signal a vitreous hemorrhage or retinal detachment that needs urgent care. Even without alarming symptoms, regular check-ups are your best protection, because early-stage changes are often silent.

Formulas traditionally used for diabetic retinopathy
5 formulas across the patterns above. The right one depends on your pattern — start with the quiz if you're unsure which fits.
A classical formula that nourishes the body's cooling Yin fluids while clearing excess internal heat. It is commonly used for symptoms such as hot flashes, night sweats, tinnitus, sore throat, dry mouth, and low back aching that arise when the Kidneys become depleted and the body overheats from within. It builds on the famous Liu Wei Di Huang Wan (Six Ingredient Rehmannia Pill) with two additional cooling herbs.
A classical three-herb formula used to restore vitality when both Qi and body fluids have been depleted. It addresses fatigue, shortness of breath, excessive sweating, dry throat, and weak pulse caused by heat exhaustion, chronic illness, or prolonged coughing that has weakened the Lungs. In modern practice, it is also widely used as supportive treatment for heart conditions including heart failure and irregular heartbeat.
A classical formula designed to nourish the Liver and Kidneys in order to support eye health. It is used for symptoms such as dry or gritty eyes, sensitivity to light, blurred vision, and watery eyes caused by Wind, all stemming from an underlying deficiency of Liver and Kidney Yin. It builds on the well-known Liu Wei Di Huang Wan (Six-Ingredient Pill with Rehmannia) by adding herbs that specifically benefit the eyes, nourish the Blood, and calm overactive Liver Yang.
A classical formula that both nourishes and invigorates the Blood, used to address menstrual irregularities, period pain, and other conditions caused by Blood stagnation combined with Blood deficiency. It builds on the famous Si Wu Tang (Four-Substance Decoction) by adding Peach Kernel and Safflower to strengthen its ability to move stagnant Blood and promote healthy circulation.
A classical formula that gently warms and supports the Kidneys to restore vitality, fluid balance, and lower body warmth. It is used for people with Kidney weakness who experience lower back soreness, cold legs, frequent urination or difficulty urinating, and general fatigue. Unlike strong warming formulas, it uses a small amount of warming herbs alongside a larger base of nourishing ingredients, working gradually to restore the body's natural balance.
In early non-proliferative stages, many patients notice less eye dryness and clearer vision within 4-8 weeks of consistent herbs and acupuncture. Retinal changes visible on exam take longer - typically 3-6 months for stabilization of hemorrhages and exudates when the pattern is primarily Yin deficiency or Qi and Yin deficiency. Advanced proliferative disease with Blood Stagnation and mixed deficiency patterns requires a longer commitment, often 6-12 months, to support the eye while working alongside conventional care.
Treatment principles
Across all patterns, the treatment of diabetic retinopathy rests on two pillars: nourishing what has been depleted and clearing what has accumulated. The underlying depletion is almost always Yin, often spreading to Qi and eventually Yang, so formulas center on herbs that moisten, cool, and rebuild the body's reserves - like Shu Di Huang, Gou Qi Zi, and Mai Dong.
At the same time, the heat and blood stasis that complicate the picture must be gently cleared using herbs like Dan Shen, San Qi, and Zhi Mu, so the retina's tiny vessels can heal.
What changes from pattern to pattern is the emphasis. In early Yin deficiency with Empty-Heat, the priority is cooling and moistening. When Qi and Yin are both low, treatment adds Spleen-strengthening herbs like Huang Qi and Shan Yao to lift the energy that holds blood in place.
When Blood Stagnation dominates, blood-moving herbs take center stage, always supported by enough nourishment to avoid further damage. This layered, adaptable approach is what makes TCM uniquely suited to a condition that evolves over many years.
What to expect from treatment
Most patients begin with weekly acupuncture and daily herbal formulas, taken as teas, powders, or easy-to-swallow granules. You may notice subtle shifts first - less eye dryness, better sleep, more stable energy - often within 2-4 weeks. The retinal changes that matter most take longer to stabilize, typically 3-6 months, and your ophthalmologist will track these through regular eye exams.
Progress is rarely linear. You might have a period of clear improvement followed by a plateau, which is normal as the body integrates deeper healing. The key is consistency, because TCM is gradually rebuilding the internal terrain that allowed the retinopathy to develop, not just suppressing a symptom.
General dietary guidance
The best diet for diabetic retinopathy from a TCM perspective is one that cools and moistens the body while supporting stable blood sugar. Favor Yin-nourishing foods: steamed leafy greens, goji berries, black sesame, cucumber, pear, and moderate amounts of fish or duck. These help replenish the fluids that long-standing diabetes has consumed.
At the same time, avoid foods that add heat or dampness - spicy peppers, deep-fried dishes, excessive alcohol, and greasy meats. Eat at regular times, chew thoroughly, and don't overload the stomach, because the Spleen's ability to transform food into usable Qi is already compromised. Small, warm, cooked meals are more supportive than large, cold, raw ones.
Combining TCM with conventional treatment
TCM treatment for diabetic retinopathy is designed to complement, not replace, your conventional medical care. Continue all prescribed medications, eye injections, and regular ophthalmology appointments. Herbal formulas that contain blood-moving herbs like Dan Shen or San Qi may have a mild blood-thinning effect, so if you are taking anticoagulants or antiplatelet drugs, both your TCM practitioner and your prescribing doctor must be aware.
Because some herbs can gently lower blood sugar, monitor your levels when starting treatment and share your full herbal list with your endocrinologist. With open communication, TCM and Western medicine can work hand in hand - one stabilizing the eye from within, the other intervening with precision when sight is acutely threatened.

Safety & special considerations
-
Sudden loss of vision in one eye — may indicate a major hemorrhage or retinal artery occlusion; requires immediate ophthalmological evaluation
-
A sudden shower of new floaters or flashes of light — often signals a retinal tear or detachment, which can lead to permanent vision loss if not treated urgently
-
A dark curtain or shadow moving across your field of vision — classic sign of retinal detachment; go to an emergency room or eye casualty immediately
-
Severe eye pain with redness and headache — could be acute glaucoma, especially if accompanied by nausea; requires urgent pressure-lowering treatment
-
Any vision change that occurs suddenly or worsens over hours rather than weeks — acute changes need prompt assessment to rule out sight-threatening events
Audience-specific guidance — open what applies to you
Pregnancy increases blood volume and can accelerate diabetic retinopathy, especially if blood sugar is poorly controlled. TCM treatment during pregnancy must be extremely cautious. Strong blood-moving herbs such as Hong Hua (Carthamus tinctorius), Dan Shen (Salvia miltiorrhiza), and San Qi (Panax notoginseng) are contraindicated due to the risk of miscarriage. Even gentle formulas like Zhi Bo Di Huang Wan should only be used under strict supervision, often with Zexie (Alisma) removed.
Acupuncture is a safer option, but points such as Sanyinjiao (SP-6), Hegu (LI-4), and any abdominal points are strictly avoided. Treatment focuses on gentle Qi and Yin tonics like Huang Qi (Astragalus) and Shan Yao (Dioscorea), along with dietary therapy to stabilize blood sugar.
Most TCM herbs used for diabetic retinopathy are compatible with breastfeeding, but caution is still needed. Very cold herbs such as Zhi Mu (Anemarrhena) may pass into breast milk and cause infant diarrhea or digestive upset.
Blood-moving herbs should be used in minimal doses. Gentle Qi and Yin tonics like Huang Qi, Shan Yao, and Gou Qi Zi (Lycium barbarum) are generally considered safe. Acupuncture remains an excellent option during lactation. Always coordinate care with your lactation consultant and TCM practitioner to ensure the safety of both mother and baby.
Diabetic retinopathy is rare in children, typically occurring only after many years of type 1 diabetes. When it does appear, the patterns are usually Yin deficiency with heat or Qi and Yin deficiency. Herbal dosages must be reduced to one-quarter to one-half of adult doses, and treatment must be closely integrated with endocrinology care.
Children may not articulate visual changes clearly, so regular eye exams are essential. Acupuncture is often poorly tolerated in young children, and gentle massage or dietary adjustments are preferred as supportive measures.
In the elderly, diabetic retinopathy often presents with advanced deficiency patterns, particularly Kidney Yin and Yang deficiency, layered with blood stasis. The treatment principle emphasizes gentle tonification and mild blood-moving. Herbal dosages should be lower - typically two-thirds of the adult dose - to avoid taxing a weakened digestive system. Polypharmacy is a serious concern; monitor for interactions with anticoagulants or antiplatelet drugs when using blood-moving herbs.
Acupuncture is well tolerated, but avoid strong stimulation. Treatment timelines are longer, and the realistic goal is often to slow progression and preserve remaining vision rather than reverse established damage.
Evidence & references
Acupuncture and Chinese herbal medicine show promise for diabetic retinopathy, but the overall evidence quality is moderate. A 2018 meta-analysis of Qi Ming granule, a widely used TCM formula, found significant improvements in visual acuity and a reduction in retinal microaneurysms when added to conventional treatment.
Several small randomized controlled trials suggest that acupuncture can improve retinal blood flow and visual function. However, many studies are limited by small sample sizes, lack of blinding, and short follow-up periods.
Preclinical research provides mechanistic support. For example, the formula Bie-Jia-Ruan-Mai-Tang has been shown to inhibit retinal neovascularization and induce apoptosis of retinal vascular endothelial cells in diabetic mice. While these findings are encouraging, well-designed, large-scale clinical trials are still needed to confirm efficacy and safety. Patients should use TCM as a complementary therapy alongside standard ophthalmologic and diabetic care.
Key clinical studies
This preclinical study demonstrated that Bie-Jia-Ruan-Mai-Tang significantly reduced retinal neovascularization in a mouse model of diabetic retinopathy by promoting apoptosis of pathological endothelial cells, providing a mechanistic basis for its traditional use.

Frequently asked questions
Common questions about using Traditional Chinese Medicine for diabetic retinopathy.
Acupuncture and herbs cannot regrow retinal tissue that has been destroyed, but they can improve the environment that allows the condition to progress. By reducing heat, nourishing Yin, and moving stagnant blood, TCM aims to stabilize fragile vessels, reduce leakage, and slow or halt further damage. Many patients find their vision stabilizes and that they need fewer invasive procedures over time.
Most herbs used for diabetic retinopathy are gentle and safe alongside standard diabetes drugs, but some - like Huang Qi (astragalus) and Shan Yao (Chinese yam) - can modestly lower blood sugar. You should monitor your glucose closely when starting herbs and inform both your TCM practitioner and your prescribing doctor. Never adjust your insulin or oral medications without medical guidance.
In the early stages, TCM may help delay or reduce the need for injections by calming the retinal vessels. In advanced disease, injections remain a critical tool to prevent vision loss, and TCM works alongside them - supporting the eye's healing environment and potentially reducing the frequency of treatments. Always follow your ophthalmologist's recommendations for sight-threatening changes.
You'll typically take herbs daily and receive acupuncture once or twice a week initially. Improvements in eye comfort and overall energy often appear within the first month. Measurable retinal stabilization usually requires 3-6 months of consistent treatment, with longer courses for advanced proliferative disease. TCM is a marathon, not a sprint - the goal is to shift the internal terrain so the retina becomes more resilient over time.
Yes, this is one of TCM's strongest contributions. By addressing the root deficiencies - nourishing Yin, supplementing Qi, and moving blood - treatment aims to create an internal environment where retinal vessels are less likely to leak and bleed. Early intervention when you first notice mild blurring or dry eyes offers the best chance of slowing progression and protecting your vision long-term.
Yes, when performed by a licensed and experienced practitioner, acupuncture near the eyes is very safe. Points like Jingming (BL-1) and Qiuhou (EX-HN-7) are needled with fine, single-use needles using gentle technique. You may feel a mild sensation but not pain. Always ensure your practitioner is trained in ophthalmic acupuncture and uses proper sterilization.
Focus on foods that nourish Yin and support the Liver and Kidneys: dark leafy greens, goji berries, black sesame, cucumber, pear, and moderate amounts of high-quality protein like fish or duck. Avoid spicy, deep-fried, and overly heating foods that can flare empty heat. Consistent meal times and avoiding cold, raw foods in excess help protect the Spleen's ability to produce Qi and blood for the eyes.
